DP_PPI to fiber optic module connects 200PLC Kingview fiber optic communication in cooling tower control system case [Copy link]

Background introduction:

Siemens 200 CPU226PLC uses Xingda Easy Control DP to fiber optic module to convert PPI to fiber optic in 200PLC system to realize PCL and Kingview 2.5km PPI communication data collection and monitoring. Since the original distance between 200plc and Kingview was relatively close, PPI communication was adopted. Due to civil engineering reasons, the host computer collected data centrally in the central control room 2.5km away.

Network expansion diagram below:

Since the communication after the transformation is changed from PPI to optical fiber , the communication mode is still PPI, so the configuration screen and address parameters of the host computer are not allowed to be changed, so the purpose of installation and use is achieved, saving manual debugging costs
