PLC's domestic and international situation and future prospects

In the industrial production process, a lot of switching sequence control, which in accordance with the conditions of the order to move a logical and controlled chain protection action in accordance with the logic of relations, and a large number of discrete data collection. Traditionally, these functions are controlled by pneumatic or electrical input output module plc system to achieve. 1968 American GM (General Motors) companies to replace the electrical control device, following the requirements of the second year, the United States Digital Equipment Corporation (DEC) developed a control device based on the integrated circuit and electronics technology, first applied to adopt procedural means electrical control, this is the first generation of programmable logic controller, called plc digital io module Programmable, is recognized as the world's first PLC. Limited to the level of development of computer components and conditions at the time, early PLC discrete components mainly composed of small and medium-scale integrated circuits that can perform simple logic control and timing, counting function. 20 in the early 1970s there has been a microprocessor. It will soon be introduced into the programmable controller, so that PLC increased computing, data transmission and processing functions, complete with real industrial control devices computer features. In order to facilitate the familiar relays, contactors systems engineering and technical personnel, and the relay circuit programmable controller uses a similar ladder as the main programming language, and will participate in computing and computer storage elements are processed to relay name.

PLC's IO module input sampling stage works

PLC works: When the PLC into operation, their work is generally divided into three stages, namely the input sample, a user program execution and output refresh three stages. Completion of the three phases is called a scan cycle. During the entire operation, PLC's CPU to a scanning speed of repeating the above three phases. (A) input sampling stage: input sampling stage, PLC scan mode sequentially reads all input status and data stored within them plc analog io module image area corresponding the unit.

Some of the role plc input output modules

Our automated industrial chain two - plc digital io module underlying field devices (especially transmitters and actuators), the upper integrated automation software is the weakest link. Our own design and manufacture of smart transmitters, only 9% of the domestic market. Top-level control software integration weak, partly because the process of industrial enterprise users do not understand the characteristics of the profound lack of experience accumulated, thereby constraining the top-level integration capabilities and quick access to intelligent micro china programmable logic controller plc market segments (industrial enterprises by the state's ability to design qualification prescribed threshold is one of the reasons). User market for their industrial technology / product does not agree, restricted independent research and development of industrial products, opportunities for improvement practices.
For these reasons, the control system made ​​it difficult to enter the critical major projects, core, major equipment, most of the analog output modules in this market is still a monopoly of foreign industrial control systems.
(B) PLC input output modules, for the majority of the discrete factory automation PLC system, the situation is not optimistic.
The current scope of application of PLC technology, in addition to covering a large chemical industry, power companies in almost all industries. However, the current application of the PLC market, more than 95 percent are from foreign products, domestic enterprises absolute disadvantage occupation.

 The main difference from other computers is that harsh conditions (such as dust, moisture, heat, cold), and a facility for extensive plc IO module arrangements PLC's armor. These PLC connected to sensors and actuators. PLC read limit switches, analog process variables (such as temperature and pressure), and a complex positioning system location. Some use machine vision. In the side of the actuator, PLC operation of the electric motor, pneumatic or hydraulic cylinders, magnetic relays, solenoids, or analog outputs. Input / output configuration can be built a simple programmable logic controller, or the PLC can be attached to a computer network to insert external PLC I / O modules.

input module plc Wiring

 During normal smart plc operation, different methods of connecting the field device wires to the I/O Modules offer no significant advantages over each other. Field devices can be wired differently to provide safety and protection in the event of failures in field devices, or faults in their electrical circuits.
"Backups" are field devices required to operate properly to provide safety in the event of a failure of another device or fault in a circuit. If the circuit for a backup is not affected, the backup should operate properly and continue to provide safety.
 The safety of input module plc sequentially controlled systems, industrial facilities, and even personnel frequently depends on field devices (especially the backups) operating properly.
  Sink and Source connections at a DC plc analog input module are defined by whether or not the field device DC power comes from a power supply external to the PLC. Neither connection has any fault protection advantage.

plc IO module programming

PLC programs are typically written in a special application on a personal computer, then downloaded by a direct-connection cable or over a network to the PLC. The program is stored in the plc IO module either in battery-backed-up RAM or some other non-volatile flash memory. Often, a single PLC can be programmed to replace thousands of relays.[7]
Under the IEC 61131-3 standard, plc analog output module can be programmed using standards-based programming languages. A graphical programming notation calledSequential Function Charts is available on certain programmable controllers. Initially most plc logic controller utilized Ladder Logic Diagram Programming, a model which emulated electromechanical control panel devices (such as the contact and coils of relays) which PLCs replaced. This model remains common today.

input module plc choice

input module plc choice
 input module plc choices: 1. Select the power module power module choice is simple, just consider the power supply's rated output current on it. Rated current of the power module must be greater than the total current consumption of the CPU module, I / O modules, and other modules. input module plc select only the modular structure of the PLC, the PLC does Programmable Output Module  not exist for the monolithic power of choice. 2. input module plc programming choice for small control system or PLC system does not require on-line programming, generally used cheap simple programmer. For Chinese and complex systems composed of high-end PLC or need online programming PLC systems can be equipped with powerful, easy programming smart programmer, but a smart programmer expensive. If you have an existing personal computer, you can use the PLC programming software package for programming the function on a personal computer. 3. Writer's choice in order to prevent interference due to plc communication modules  voltage variations and other factors make lithium destruction RAM, users and programs can be selected EPROM writer, through which the user program solidified in EPROM. Now some PLC or EPROM programmer itself has written functions.

How to design output module plc in three-wire constant current source driver circuit

output module plc due to the temperature of the integrated operational amplifier parameters that affect not as a transistor or FET parameters affect significantly the integrated amplifier composed of a constant current plc communication modules  source with the stability better, more constant performance advantages. In particular, the need to ground at the load end of the occasion, received a wide range of applications. Dual op amp constant current source. UA1 amplifier output module plc which constitute adder, 1) load can be grounded; 2) When the op amp is a dual power supply, the output current is bipolar; 3) constant current size adjusted by changing the input reference datum reference resistor Rref0 size to achieve, it is easy to obtain a stable small current calibration and compensation.
Since the resistance of the mismatch, the  plc power supply module voltage across the reference resistor output module plc Rref0 will affect the load end of the driving voltage Vb. The same time as a constant current source, and will definitely change with load changes, which will affect the stability of the constant current source. Obviously, this high-precision constant current source is unacceptable. So R1, R2, R3, R4 selection principle which four resistors is to try a small mismatch, and every size of resistor mismatch direction to be consistent. In practice, a lot of the same batch can be screened precision resistors, where resistance is close to elect four resistors.

Some of the sequence output module plc

An automatic identification IO modules, IO consecutive numbers down by a physical connection. But the program even without the IO module may still running down. Because IO address is mapped to the cpu's memory, program memory operations generally.
2 software configuration and download it to the cpu to identify the IO module. Once the module occurs from such failure, cpu system plc communication modules  fault alarm can be issued immediately, the hardware must meet the configuration settings, and IO address mapping can also be freely allocated memory space.
I / O expansion bus, there are many, output module plc various PLC manufacturers are different, or look at the refresh rate. Slow, then you can use SPI and the like, and then a little faster, then you can do a physical interface with FPGA, there is one of the fastest Industrial Ethernet.
Simple application can even use the serial port to do. I / O port expansion is the I / O address to the CPU memory map, but  plc logic controller this map is a combination of software and hardware self-identification are defined manually or through assignment and allocation. May be in the exhaust line is whether there should be a line behind the front of the module has a successor in charge of the report module, if the module behind the successor state that level on this line, and when no module is not the same, so that they can be judged No follow-up module, CPU module communicates with other modules using the relay mode, the transmission down a level, that is, only the CPU module and from his recent communication module, output module plc and other modules if you want Communication would have to transit through  plc controller manufacturer other modules, so that modules are installed in accordance with the order of the address of the module can be determined, on power CPU perform a self-test program, each module to report their labeling information so that you can know the total CPU module the number of mounted modules, each module location and type of each module.

How to select plc IO module manufacturers

Domestic production plc IO module manufacturers are said to have many thousands, how can choose their own power supply module manufacturers do?
1, for the size of their own requirements. Some foreign brand quality is really good, but the price is not every user can programmable plc  accept, plc IO module and delivery compared to domestic brands, is very long. For some of the larger domestic supplier of power modules also have this problem, if you set its main ship models of non-models, delivery is also not guaranteed. If you own custom made a special power, for small customers, is simply unthinkable. Because SMEs did not like Huawei, ZTE delivery platform choice, to choose their own scale enterprises, is very important. VST such as power companies, specifically for SMEs to provide power solutions, to provide customized services.

Select the output module plc switch output module

The output module is required for the internal drive signal to PLC low voltage signal is converted to an external output device. The main selection should consider the type and size of the load voltage, the system latency requirements, whether state and frequent load changes.
1. Select the output mode
Digital output module has three output modes: output module plc relay output, thyristor output and transistor output. Relay outputs are cheap, both to drive an AC load, but also for the DC load, but  Programmable Output Module also for a wide range of voltage magnitude, a small voltage drop, and the ability to withstand strong transient over-voltage and over-current. But it belongs to have contact elements, its movement is slow, short life, poor reliability, and therefore, does not only apply to frequent on-off occasions. When used to drive inductive load, output module plc operating frequency does not exceed its contacts 1Hz.
For frequent load off, you should use triac output or transistor output, they are non-contact components. But only for analog output module  Triac output AC load, and transistor output can only be used for DC load.
2. Select the output wiring of different output wiring of the PLC, are generally grouped outputs and two separate outputs, outputs are grouped several output points as a group, sharing a common terminal between the groups are separated , respectively, using a different power. And each output point delimited output has a common, mutual isolation between the outputs, each output point may use a different power source. The main species Programmable Output Module  should be based on how much power the system load may be. General Integral PLC outputs both groups, there are also separate output.

Selection of low-cost analysis of the input module plc

PLC because of its high reliability , simple programming , versatility , small size, compact structure, convenient installation and maintenance , etc. , and in the industrial control has been widely used . PLC modules are generally divided into the following categories : switch input modules , digital output modules , analog input module , analog output modules. Industrial  plc digital input output module control, especially in the field of process control and control need to collect more than analog , input module plc thus PLC analog input and output modules require more, and analog input and output modules are more expensive, increase the analog input and output modules increases the cost and reduces the cost of the entire system , input module plc limit the application of PLC. This paper presents a communication -based analog input and output modules extension method seeks to solve this problem based  Programmable Input Module on analog communication input, output module extension methods

MAX187 is a 12-bit serial A / D, has a high conversion rate , the sampling frequency is 75kHz, suitable for high precision here all the way 12-bit analog output , for example, the design will be  plc intelligent controller using 12 D / A converter chip MAX531 to achieve the number of touch conversion. We MAX531 op amp output termination , the analog output is adjusted to 0 ~ 5V, the output part of the hardware circuit shown in Figure 3 . Here , MAX531 is a 12-bit serial D / A, has a higher conversion rate...

output module plc connect to 4G network test

In the end how fast network speeds of 4G? Prior to this, have repeatedly reported that several times faster than 3G networks to 4G, output module plc only a few minutes to download several G movies, etc. These  plc digital input output module reports, many of which are advertising in business, few real The person tested and the test results posted for your reference. In Baidu Encyclopedia, also known as 4G systems capable of speeds of 100Mbps download 2000 times faster than dial-up Internet access, upload speed can reach 20Mbps. At present, many of my friends like to watch videos online, I also watch movies with China Mobile TD-LTE 4G network, watch the whole video is  industrial automation plc very smooth, output module plc no obvious lag, the test results show that the speed of 4G is expected to exceed the current 3G network, but the key will have to see after the commercial price. While China Mobile 4G network Declaration on how high rate, but I was in the People's Square, whether on foot or in a moving vehicle test, there will be a few corners no 4G network, which is only a question of my own discovery.
Here I can only say that network optimization is plc analog io module  not achieved overnight, the majority of users are direct witnesses, let us speak with the facts!

output module plc, which has several outputs in the form of general

Common plc output module, which has several outputs in the form of general PLC switch output interfaces commonly used by the output of the switching device, there are three different types: output module plc is a relay output, transistor output and bidirectional thyristor output, output module plc. PLC relay output is to use the relay contacts and coils internal  plc sequence of events recording module circuitry with an external load circuit is electrically isolated from the PLC. Transistor output type PLC via opto-coupler transistor is turned off or turned on allows to control an external load circuit, while PLC internal circuit and transistor output circuit is electrically isolated. Relay outputs can drive AC or DC loads, but the long response time, low operating frequency, but the load capacity of the strongest; while the response speed of the transistor output and bidirectional thyristor output interface, high plc input module  operating frequency, but the former can only be used to drive DC load, which can only be used for AC load. Digital output generally two types: type transistors, relays sex. Analog output generally two kinds: voltage, current type.

output module plc introduce some other

Inductance coil , you are fully enclosed inductors , in order to avoid electromagnetic interference between the coils and the coil is enclosed in an iron box, the CPU power supply module is pulse input module plc  used to compensate for current limitations and to provide a stable current to the CPU , safeguard its stable job, it can be initially identified by the motherboard power phase , output module plc has several boxes is several -phase power supply , independent of each phase current power supply provides all the way , because the CPU is a high- power hardware into multiple power power lines can reduce the burden on every road , output module plc reduce the heat every road in order to have better stability in CPU overclocking or running, it 's the number the better , because there is a large current through the plc input output modules  high temperature is normal, as long as your computer using a no-show, do not ignore the problem , which is why high-end motherboard on which you want to increase the heat sink block and Northbridge heat pipe and connected , you can add . That is the cpu power supply modules, three on a 3 -phase power supply , said cpu , high-end motherboards come with yo radiator at the top, there is no low-end motherboard heatsink is exposed . Best to make  plc modular your cpu fan blowing where , if it is not on the blow does not matter. Should not burn unless your motherboard is the second line of low-end motherboard.

Numerical plc IO module reads always changing, what is the reason

Roughly divided into the digital input DI, digital output DO, analog input AI, analog output AO. Digital inputs and outputs are generally of 24V. Class 2 4 kinds of analog quantity, category 2 are voltage-and current-mode. There are 0-10V Voltage and -10 to 10V. Current  plc communication module type mainly 4-20MA ,0-20MA. plc IO module and the module through the A / D converter to convert analog into digital +32767 to -32768 between then under control. If there is an alarm relay on the meter, then set the alarm temperature on the instrument, the output relay is directly connected to the digital inputs plc and public clients. If there is no alarm relay on the meter (meter is no such general alarm relay), direct access to analog values ​​plc to make their  plc analog input module own alarm in the program. And direct access to the analog case plc, and because plc and instrumentation wiring different models differ, analog signal inputs can be 4-20mA, it can be 0 - (5) 10V, can also be thermal resistance and the like, the situation is more, the need for specific models can be. Potentiometer is actually sliding rheostat, string a fixed value resistor, calculate resistance. If you do the experiment, find a 24v power supply, and then take analog output module  the fixed value resistor voltage or voltage across the potentiometer input into the AI, they have to be considered a good range. I remember before the first experimental range card transferred to the correct location. The best add isolation (barrier like), to protect AI point.

What input module plc automatic control system

input module plc is equivalent to the machine 's brain , we compiled the program is equivalent to the knowledge of people hold grip and rules .
The machine equivalent to the human body, used to  pulse input module plc perform various operations of the PLC .
Electricity, gas, liquid, etc. is equivalent to human muscle and nerve , PLC issued a directive by electricity, gas, liquid , such as the energy to the machine , the machine will perform .
The external sensor feedback to PLC, equivalent to the human eye , nose , etc., will be back to things outside the brain .
That is to take a person or animal analogy , PLC is the brain , PLC combined with the machine equivalent combination of the  Programmable Output Module human brain with the body , but inside the human brain is much more complex process than the PLC , but the people sensitivity and accuracy of the brain is not as PLC. PLC application in China is growing very rapidly. With the rapid development and continuous improvement of basic automation level of China's economy over the next period of time PLC in China will maintain high growth momentum.
When applied to generic PLC equipment can think of it is an embedded controller, but relatively general embedded controller plc IO module  and PLC side has higher reliability and better stability. Some users had encountered in practical work with embedded controllers , is now being gradually replaced by embedded controllers PLC with generic or customized PLC.

Analog input and output modules at different points plc cpu modules Module

You say that your sensor with analog output, analog input, (meaning the module is to convert your voltage or current value to digital, then the table can be calculated by the slope of your current temperature or pressure.)
If you want to read when the temperature or digital input plc  pressure values, plc cpu modules that you have a sensor with analog output and analog output. So if you buy an analog module, connect the analog module with PLC, analog output and input with sensor modules connected (of course there are a wiring diagram so you do not have to worry about the module). When through the power after the sensor module automatically checks the current value after converting it into digital, it you calculate the slope of the  micro smart plc slope according to the formula sheet, so that you will be able to know a current value of the temperature or pressure. Digital input and output signals that switch signal, 1 or 0, analog signals, there are two kinds of voltage or current signal, typically pass over the transmitter  plc module signals, such as pipe pressure detected by the pressure transducer, it will output an analog signal 4 - 20ma or 0-10V signal to the PLC, PLC for data processing.

output module plc analog input and output modules

Central Standing Committee in the position control system uses servo motors and stepper motor as the drive unit. To adopt open-loop control , closed-loop control can also be used . For stepper motor, we can use to adjust the speed of change in the mechanical transmission pulse operating speed . Use FX series PLC, positioning plc ethernet module  pulse output in the form of units or modules , you can achieve positioning point or points . Here pulse output module and positioning control module FX2N series .
( A ) the pulse generator pulse module to complete a positioning unit independent axis , which is specified by the number of pulses to provide a servo or stepper motor drive amplifier to achieve. Only for the FX2N sub-series , with the industrial plc  FROM / TO instruction set various parameters , positioning readout value and speed . The module occupies 8 I / O points . The output pulse train up to 100KHZ 's .

( 3 ) positioning controller can control two axes. Perform linear interpolation, circular interpolation , or a separate two-axis positioning control , the maximum output pulse train is 200KHZ ( During interpolation, up to 100KHZ)

output module plc analog input and relay output modules problems

Upper and lower limits of analog input values ​​are set to 20 and 0 , had  plc analog io module everything normal, in the absence of the analog signal access , the software displays a value of 0 , there is signal access , they also have a normal display, but under normal use two or three days , the upper and lower limits remain unchanged, the analog input value in the absence of wiring is 6.8 , all the channels I have tried are 6.8 , then the company gave me a new simulation input module , installed after the beginning is normal, but it is the same problem in a couple of days later , I ask an expert what causes ? Urgent
Also this PLC as well as a relay output module , 2, 3 and 4-channel connection of solenoid valves, found often there will be a problem , sometimes when I start solenoid valve, status lights all of a sudden relay plc cpu modules  output modules are extinguished , the network does not pass if the output has an inductive load , inductive load at the moment there pass off thousands fleeing negative voltage power module and power module fleeing after each power unit , causing damage to electrical components . So best to separate inductive load power . I had always felt that the problem is not , then burned two PLC know, sometimes it is really necessary to separate power supply.

How to choose the output module plc input and output interface module type

PLC is an industrial control system, it is the object of industrial production control equipment or industrial processes , industrial work environment field . Its links with the industrial production process  digital output plc is through I / O interface module to achieve.Through the I / O interface module can detect various parameters controlled production process , and these field data as control information on the controlled object . While the I / O interface module of the processing result to the controller or industrial processes controlled device , thereby driving the various actuators to achieve control. PLC information collected from the scene and outputs a control signal to external devices are required to go through a certain distance , in order to ensure that the information is correct , PLC 's I / O interface module has better anti-interference ability . According to actual needs , under cpu modules  normal circumstances , PLC has a number of I / O interface modules , including digital input module , digital output modules , analog input module , analog output modules as well as some other special modules should be used according to their selected features .

PLC controller works

Although the ladder program used by many PLC often use such as relays, timers and counters name, but not the internal PLC entities have the hardware , but in the memory and logic control programs do programmatically edit and output elements borrowed from the connect an external china industrial automation plc entity controlled mechanical device to do . So can greatly reduce the space required for hardware controllers . PLC ladder program execution actually works is the first progressive ladder code to scan and read into the CPU and finally perform control operations. Throughout the scanning process includes three steps , "Input status check ", " run " , "Output status updates " as follows:Step one " input status check ": PLC First check the status of each point switch or sensor inputs connected components of ( 1 or 0 for on or off ) , and its status is written in the corresponding memory location Xn. Step two " running " : progressive ladder program will take into the CPU operation , if the program is running you need to enter the contact state , CPU direct inquiries removed from memory. Operation result is stored in the output coil plc analog output modulesmemory location corresponding to withhold response to the output Yn. Step Three "Output status update " : the step two of the output status update to the PLC output unit contacts , and return to step one . This third step is called the PLC scan cycle , and the time required to complete the PLC called the reaction time ,the time of the PLC input signal if the reaction time is less than this , there is the possibility of misreading . After each run the next time the program before execution , output and input status will be updated once, so this mode of operation as an output , said input of " the end of the regeneration program ."

output module plc plc domestic market due mostly occupied by foreign products

The first is technology, in the rapidly evolving international situation plc, the majority of our plc manufacturers also do not own independent intellectual property rights, to participate in international competition PLC products, one of which is the development of strength is not plc digital input output module  enough. Although capital investment, production and quality management and other factors also account for a very large proportion, but the quality of the product plays a decisive role in the R & D investment, R & D results and products of the production process and so on. The technology is permeated with which every aspect of the development of core technologies plc, the follow-up product development, technological level of the production process is to determine the quality of products, how to  output module plc further enhance their strength in technology, domestic brands will gain market key to competitive advantage.
Followed by the competition, because most of the domestic market plc occupied by foreign products, large and medium-sized plc products, almost all monopolized by a few big foreign companies, as China continues to expand the use of plc market, several major foreign companies almost every year for the market introduction of new products, once the user using the new product, they plc analog output  will gradually raise the market price, if the country does not own independent intellectual property rights, competition in the economy can only be in a passive position. So domestic plc manufacturer must have their own independent research and development of products, the only way to compete in an invincible position in the market.

The main job of the output module plc

SCM can be used to direct the development of control systems, but very demanding for the developer (not the general level capable of ) , long development cycles, high costs ( for some large decency you need to Nanda plc power supply module  do a little experiment , a printed circuit board requires a considerable the cost , you can say you use the emulator to develop experimental board , but I have to tell you , do you just verify the feasibility of hardware and software , does not mean that can be used in industrial control systems, industrial control systems because Immunity requirements for very high stability first , rather than the performance of the first , so you must constantly  Nanda plc input output modules test the circuit board design , improvement ) when you solve these problems, you will find that you have done a PLC , of course, If you need to use someone else can easily use the software you'll need a set , so you may not need to tell others about your circuit ( you can not tell anyone ) .
       Many people feel very mysterious PLC , PLC is actually very simple , in addition to its internal CPU speed , the Nanda Programmable Output Module  other functions not as common microcontroller . PLC usually uses 16 or 32-bit CPU, serial communication with the outside world with a channel or two , and has an internal timer can , to improve the reliability plus a watchdog timer is enough .

How to use the input module plc 's multi- segment level setting , display, alarm and automatic level control

In many production areas , it is often necessary to tanks , storage tanks, pools and other containers of liquid level monitoring to the usual traditional relay -contact control , multi- use hard-wired electrical  plc manufacturer appliances , poor reliability, high degree of automation , has there are many enterprises to adopt advanced controller to transform the traditional exposure control , greatly improving the reliability and automation level of the control system , providing a more reliable production guarantee. This paper describes a programmable controller (PLC) A method for monitoring liquid level , its simple circuit structure and low investment ( Available renovation of existing facilities ) , not only a high degree of automation control systems , but also has online modify the function , flexibility, suitable for Nanda cpu module plc  multi- level monitoring applications.
1 . Control requirements
The control system can be based on the needs of production is divided into multi- level set , and segment display , when the minimum level to start automatically when you add liquid feed pumps , liquid level reaches the set value audible alarm and stop the pump ; the operator can turn plain by the OK button to lift the alarm sound , flashing lights ; system with manual / automatic control modes , and a test function.
2 . PLC Selection
In this case , select the PLC PLC should consider the cost performance , high reliability, choice , quite , load capacity suitable , affordable PLC. This article introduces the four level control object , for example, according to analysis and comparison of a variety of plc input output modules  factors and control system input and output points requirements.
3 . System hardware configuration
To achieve the level of manual / automatic control, you need to enter the mouth 12:00 , 8:00 outlet , use C20P 20点PLC I / O unit , optically isolated input and output isolation relays , load capacity ; liquid level detection using Reed tube sensor , manual / automatic conversion , run / test conversion and level settings using double- knob manually start the pump , the pump stops and confirmation test using normally-open button ; selection of electronic sound alarm output and 24V DC lights, relays . See Figure a hardware configuration diagram

output module plc in control system

Programmable controller (Programmable Logic Controller) referred to a PLC or PC, is developed from the early relay logic control system, which constantly absorbing micro- computer technology to  Nanda analog output plc continuously enhance the functionality gradually suitable for complex control tasks.
 PLC viable reason is that it is more suitable for industrial field and market requirements : high reliability , simple and strong anti- interference of various programming installation, low price and long life. Than the microcontroller, its input and output ports closer to the field devices , without adding too much of the middle part or need more interfaces , so saving the plc input output modules  user time and cost. PLC lower end (input side ) of the relay , a transistor and thyristor control means for the user while the upper end is usually a microcomputer . When people use it , you can not carry out specialized training in computers , programmable controllers can be operated and programmed. Used to perform a variety of different levels of complexity of industrial control tasks. It began with a wire connected to it subtly with switching devices constitute or use different logic control sequence control . So far, the PLC programming languages ​​- Ladder can also see the shadow of the wiring . Until the late 1960s , early 1970s, the advent of the programmable controller , with the rapid development of microelectronics technology, computer technology and data communications technology, and the emergence of the  plc soe module microprocessor , PLC products towards small and ultra- miniaturization conducted a leap , and finally to the early PLC from the initial logic control, sequence control , PLC has developed into a modern logic, timing, counting , memory and arithmetic operations , data processing, communications and networking functions such as PID loop controller .

input module plc simple classification

PLC switch input and output modules can be roughly divided into two types:
One is connected to the host using the flat line, there is a cable

connected to the host using communications.
The latter is actually a complete switching measurement and control

modules, communication cables used to plc analog output module  obtain input switch status and

control commands issued by the control switch output. Contains an internal

microprocessor to achieve more complex, if you are familiar with the

microcontroller, you can try.
The former is relatively simple, its measurement and  lc soe module control are actually

done in the host, input and output modules essentially completed only two

things:
1, the input switch signal conditioning
Switch conditioning is the easiest conditioning circuitry, easy to

implement.
2, the output switch driver
Switch output driver is basically relay driver  plc programmable circuit, but also easy to

implement.
PLC is now mainly used mostly imported, not the actual complexity and

digital input and output modules are relatively simple modules, encourage

yourself or with a domestic brand!

output module plc and core have to do with the thread

Logical processor is threaded, is called a logical processor should he processor is not complete, as you can understand the basic structure of the execution unit of the processor.
Dual-core 4 thread is hyperthreading, his plc analog input output module  understanding is not dual-core simulation into four core, he is to be a core integrated two logical processors that two execution units. So that he can be like four-core processors in addition to four-threaded task, overwhelmingly in support of multi-core tasks are to support Hyper-Threading, but the dual-core 4 thread is always a dual-core processor.
Here to explain the core is there a more complex combination consisting of multiple parts, he does not just consist of the plc soe module  processing unit, the core processing unit contains something + L1, L2 + + instruction processing unit clock generator and so on. Hyper-Threading is to integrate the two core execution units.
Also you say FX6100 is a 6 core 6 threads, the plc manufacturer  current AMD processors do not use hyperthreading.

some simple instructions output module plc 's

You say that your sensor with analog output , analog input , ( meaning the module is to convert your voltage or current value to digital, then you can calculate the slope of the current form of the temperature or pressure . )
If you are asked to read the temperature or plc analog input  pressure values ​​, you must sensors with analog outputs and analog outputs. So you buy a simulation module , connect the analog module with PLC, analog output and input sensor is connected with the module ( module wiring diagram of course you do not have to worry about this ) . When the pass on the power after the current value of the module automatically detects the sensor and then convert it to digital, you calculate a formula based on its slope slope table , so plc analog io module  you can know the current value of the temperature or pressure . The same output is a voltage or current signal wiring relationship with you , then the output current is the current line , then the line voltage is the output voltage. Temperature can be equipped with PT100, if needed pressure with pressure transmitter (4-20mA output ) , then select the range to be based on the meter .
What is the analog of the PLC are the same, as long as the project based on the amount of data can be transformed .
In addition , many of the instruments have a plc temperature module  communication function or frequency output, which could save an AD module connection is also convenient.

plc IO module status of the industrial sector in general and the reasons behind

Our automation industry chain two - the underlying field instruments (especially transmitters and actuators), the upper integrated automation software is the weakest link. Our own design and manufacture of PLC micro smart plc  smart transmitters only 9% of the domestic market. Top-level control software integrated weak, partly because the characteristics of the process of industrial enterprise users do not understand the profound lack of accumulated experience, thereby constraining the top-level integration capabilities and the ability to quickly enter the market segments (industrial enterprises subject to state on design enterprise qualifications prescribed threshold is also one reason). User market for their industrial technologies / products do not agree, restricted the practice of self-developed industrial product PLC plc digital input output module  improvement opportunities.
For these reasons, domestic control system is difficult to enter the critical major projects, the core, the main equipment, the majority of this market is still a monopoly of foreign industrial control systems.
(B) for the majority of discrete factory automation PLC system, the situation is not optimistic.
 The current scope of application of PLC technology, in addition to covering a large chemical, electric power companies in almost all PLC plc cpu modules  industries. However, the current application of PLC market, more than 95% are occupied by foreign products, domestic enterprises absolute disadvantage.
Three) PLC system hard-reliance, industry, research and development platform is missing.
First, their enterprises and institutions, small scale, decentralized operations, not thrive.

Trends in embedded plc IO module

A developmental path is the development of PLC and HMI combination of hardware / software integration for the target platform , taking advantage of CASE tools, combined with various types of embedded chip development platform and a variety of input / output channels of the hardware circuit library , designed for the development of customized electromechanical equipment , with a special nature ODM PLC. This indicates that the embedded PLC has much Nanda Programmable industrial controller plc  room for development . Embedded PLC has a broader space for development in our country, first of all it is very conducive to the development of China's two major characteristics play automation industry : There is a very strong market for the electrical and mechanical equipment for the foundation , and has enough global optimal cost design and development team . We can at the lowest cost , high quality, according to custom requirements of the design , production and electromechanical equipment for embedded PLC, instead of the generic PLC.
Meanwhile, the various aspects of functional embedded PLC hardware , software, human-machine interface , communications, design  Plc logic controllers flexible, easy to cut , closer to the requirements of various grades of electrical and mechanical equipment . Embedded PLC technology based entirely on the basis of embedded systems can be used with . SoC chip , embedded operating systems and compliance with IEC61131-3 programming language standard programming environment and other advantages, making it very easy to find on the market .
In the current environment is not difficult to develop a common PLC technology breakthrough, but to seize the market requires a lot of financial and human resources invested . In the market has been one of the few large companies to carve solid today, go this route seems to be less effective. Our small PLC gratifying progress in recent years, there are practical , too, proved this judgment.
