PLC communication network
Rely on advanced industrial network technology can be quickly and effectively to the collection, transmission, production and management data. Therefore, the importance of networks in automation systems integration projects are increasingly significant, and even been suggested that the network controller is the "point of view to say.
PLC communications networking functions, it makes between the PLC and the PLC between the PLC and the host computer and other intelligent devices to exchange information, to form a unified whole, to achieve decentralized to centralized control. The majority of PLC with RS-232 interface, there are some built-in interface to support their respective communication protocols.
PLC communications interoperability has not yet been realized, the IEC provides for a variety of fieldbus standard PLC manufacturers have adopted. (Especially in large-scale control system) is concerned, select the network is very important for an automation project.
First, the network must be open to facilitate the integration of different devices and the future expansion of system scale.
Second, transmission performance requirements for different network layers, select the form of a network, this must be a more in-depth understanding of the standard protocol of the network under the premise of the mechanism; again, considering the system cost, device compatibility, on-site environmental applicability, used to determine the different levels of network standards.
