PLC developed from the traditional relay circuit, the initial PLC did not even have analog processing power, therefore, the PLC from the beginning to emphasize the logical computing power. There are many control products on the market, whether DCS or PLC, there are many manufacturers in the production and sales. For PLC systems, there is generally no or little need for expansion, because PLC systems are generally used for equipment. In general, there are few compatibility requirements for PLC, such as two or more systems that require resource sharing, which is also very difficult for PLC. And the network structure that PLC generally uses, such as the MPI total linear network, even adding an operator station is not easy or costly.
DCS in the process of development is also the manufacturer’s own system, but most of the DCS system, such as, ABB, Honeywell, GE, Schneider, etc., although the internal system (process level) of the communication protocol is not the same, but the operational level of the network platform is the same choice of Ethernet network, using standard or deformed TCP/IP protocol. This provides very convenient scalability. In this kind of network, the controller and the computer exist as a node, as long as the network reaches the place, you can arbitrarily increase or decrease the number of nodes and arrange the node position. In addition, based on windows OPC, DDE and other open protocols, the system can also be very convenient communication, in order to achieve resource sharing.
DCS generally provides a unified database. In other words, in a DCS system once a data exists in number
