Hello tiger; The screesghot below is taken from the WinCC v7.2 Communication manual. It shows the available communication protocols supprted by your version of WinCC. Notice that it supports Modbus TCP, but not Modbus RTU (serial, RS 232C) that your LS PLC can handle. https://support.industry.siemens.com/cs/us/en/view/73568736 You would have 2 choices to communicate between your LS PLC and WinCC v7.2: - purchase a specialized Modbus RTU driver for WinCC, such as this one from Allmendinger Ingeierburo:(the webpage title is erroneous, but the product discussed is for serial Modbus to WinCC comms). WinCC will act as a Modbus master, your PLC must be able to respond as a slave. https://www.allmendinger.de/Products/WinCC-Communication/Modbus-Protocols - purchase n OPC server for Modbus serial PLCs and use the WinCC OPC channel to connect to it. For example: https://www.matrikonopc.com/opc-drivers/1984/index.aspx Hope this helps, |
