PLC Remote Monitoring and program download


   PLC serial port -- remote monitoring through DTU
  • Remote monitoring of PLC based on Modbus RTU protocol
  • As long as the computer can access the Internet, it can cooperate with the Scada software to realize data communication
  • PLC and PLC (point-to-point), multi-point communication can be realized between PLC and multiple devices

   PLC ethernet port - which realizes remote monitoring and program download based on VPN network through DTU
  • Realization of PLC Remote Monitoring based on VPN network through Modbus TCP protocol
  • As long as the computer can access the Internet, it can cooperate with the Scada software to realize data communication
  • PLC remote download program can be realized based on VPN network

   DTU establishes data communication with OPC server software
  • The field serial port equipment establishes communication with OPC server through Comway virtual serial software
  • The field Ethernet port equipment establishes communication with OPC server through VPN network
  • WINCC and Scada software realize data communication through OPC server
