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.

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.
