Cpu modules plc

plc cpu module having a microprocessor digital electronic devices for digital logic controller automation and control, control commands can be loaded at any time within the memory storage and execution. By an internal programmable controller CPU, instruction and data memory, input and output units, power modules, modular plc, combined into a modular unit.
Widely used in the current field of industrial control. Prior to the programmable logic controller appears generally to be used hundreds of relays and automation systems in order to form a counter with the same functionality, but now, after the programming of simple programmable logic controller module has basically replaced these large devices. programmable plc controller system program is generally at the factory initialization is complete, users can edit their own according to their own needs appropriate user program to meet different requirements for automated production.
