The difference between the microcontroller and PLC

PLC program can be changed. Now most of the microcontroller (internal FLASH ROM) are available online-burning program, change the program so that it functions with PLC is the same. Of course, there is a curing process. You can no longer change the program like this.PLC chip, its main advantages:1: stable photoelectric isolation due to I/O … Continue reading The difference between the microcontroller and PLC
