MVP 2021 kratmel Posted March 27, 2022 MVP 2021 Report Share Posted March 27, 2022 Hi, It is clear that SСADA is a master of the network. Then tell us which Unitronics PLC you want to connect and which communication channel. Possible variants of physical communication channels RS232, RS485, Ethernet, CAN, GPS. Accordingly, the communication protocol is possible MODBUS, MODBUS TCP. Maybe I missed something else. Clarify your task and I think the forum participants will be able to help.

Fernando Castro Posted March 27, 2022 Report Share Posted March 27, 2022 Also, I remember seeing an example for communicating visilogic controllers with citec scaada, on unitronics web site. It may work for you. If you are not still able to do it please share more information to give more advice on how to do. it Quote Link to comment Share on other sites More sharing options...
