How does pcs7 communicate with other systems? Thank you. Wait around
OPC, PROFIBUS, MODBUS
If it is merely about displaying communication status on the upper-level computer, then the WINCC OPC interface can be used. If data communication with the CPU is required, then a communication module is needed; Profibus DP and Modbus RTU are commonly used for this purpose
Not long ago, Siemens representatives were here, and PCS7 primarily uses DP communication.
Siemens’ PCS7 uses Y-LINK to communicate with other systems via PROFIBUS. If it is another SCADA system, it can communicate with PCS7 via OPC; PCS7 has its own set of OPEN PCS7 components used as an OPC SERVER.
