Rifet Posted July 26, 2019 Report Share Posted July 26, 2019 Hi guys. I need help. Does any of you has experience of connecting wincc flexible 2008 to unitronix plc (visilogic 1210). This is my first time trying and I don't know where to start from. In wincc flexible I have option of "OPC" and "Modicon MODBUS TCP/IP" communication. What is procedure for reading tags from visilogic using wincc flexible? What is easier to use? Maybe OPC? Do I need to use UniOPC to read tags from visilogic plc and than connect that to wincc flexible? Btw I have no experience with OPC and this would be my first time. Thank you all Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted July 30, 2019 MVP 2023 Report Share Posted July 30, 2019 Modbus TCP/IP will probably be easier. Do you have a link on how to configure this driver in WinCC? Look at the Unitronics Help on Slave Addressing Tables to see how Modbus addresses translate to MIs and MBs. Joe T. Link to comment Share on other sites More sharing options...
