DCS usually uses a two-layer network structure. The first layer is a process-level network. Most DCS uses their own bus protocols, such as Profibus of Siemens and ABB, CAN bus of ABB, Modbus of Schneider, etc. These protocols are based on the standard serial port transmission protocol RS232 or RS485 protocol. The field IO module, especially the analog sampling data (machine code, 213/scan cycle) is very large, and there are many field interference factors, so the network standard with large data throughput and strong anti-interference ability should be adopted. The bus structure based on RS485 serial port asynchronous communication mode meets the requirements of field communication.

The sampling data of IO is converted into shaped data or real data by CPU and transmitted on the operation level network (layer 2 network). Therefore, the network standard of moderate data throughput, fast transmission speed and convenient connection can be adopted for the operation level network. At the same time, because the operation level network is generally arranged in the control room, the requirements for anti-interference are relatively low. Therefore, standard Ethernet is the best choice. TCP/IP protocol is a standard Ethernet protocol. Generally, we use a communication speed of 100Mbit/s.

The task of PLC system is relatively simple, so the amount of data to be transmitted is generally not too large, so the common PLC system is a layer of network structure. Either the process-level network and the operation-level network are combined, or the process-level network is simplified into the internal connection between modules. The PLC does not or rarely uses Ethernet.
