plc as general industrial control computer
PLC as general industrial control computer, industrial and mining-oriented industrial equipment. It is easy interface, output module plc the programming language is easy for engineering and technical personnel to accept. Ladder language graphic symbol and expression and relay circuit is very close, with only a small pulse input module plc switch on the PLC logic control instructions can easily achieve the function relay circuit. Is not familiar with the electronic circuits, computers do not understand the principles and assembly language people use computers in industrial control Plc high speed counting modules to open the door. System design, construction workload is small, easy to maintain, easy to transform PLC logic instead of using store-wired logic, greatly reducing the external control equipment wiring, the control system design and construction period is much shorter, but also becomes easier to maintain. More important is to change the program of the same device has been possible to change the production process. It is suitable for many varieties, small batch production applications.
