Siemens 200 SMART series PLC direct connection with WinCC communication

  1. Requirements description: Siemens S7200 SMART PLC can be connected to WinCC through PC Access SMART OPC software to realize data communication. By using the NET50-PN bridge module, 200 SMART PLC can be directly connected to WinCC for communication. In addition, the module also supports IP address cross-segment conversion and ModbusTCP communication functions, without the need to write PLC programs.
  2. Network topology: Connect the LAN1 port of the bridge module to the Ethernet port of the Siemens S7-200 SMART PLC, and connect the LAN2 port of the bridge module to the computer's Ethernet port.

  1. Function description:
  2. The IP address of the S7-200 SMART PLC and the computer can be in different network segments, realizing network segment crossover and isolation.
  3. The WinCC software can directly communicate with the S7-200 SMART PLC without the need for OPC intermediate software.
  4. DCS or upper-level software can communicate with the PLC through the standard ModbusTCP protocol, without the need to write communication programs for the PLC.
