PLC is developed from the traditional relay circuit. The initial PLC did not even have the processing capacity of analog quantities. Therefore, the PLC emphasized the logic operation ability from the beginning. There are many control products on the market, no matter DCS or PLC, there are many manufacturers in production and sales. For PLC systems, there is generally no or very little need for expansion, because PLC systems are generally used for equipment. Generally speaking, PLC also rarely has compatibility requirements. For example, two or more systems require resource sharing, which is also very difficult for PLC. And PLC generally adopts the network structure, such as the MPI bus network, even adding an operator station is not easy or very expensive.
