Posted 19 Dec 2019 Hi All, I am undergoing a project that requires me to connect a siemens s7-1200 with a Mitsubishi FX-3GE PLC using OPC UA. I was under the impression that Kepserver ex could do this, you ca install a 'mitsubishi suite' and a 'siemens suite' which will allow the kepserverex server to choose the drivers and connect the two plcs. Siemen's support however have told me that the s7-1200 CPU cannot function as an OPC client, and just as a server? If true, I do not understand how to get the mitsubishi FX to be a client to the siemens server, as kepserverex seemed to provide a solution. Share this post Link to post Share on other sites
Posted 19 Dec 2019 (edited) Your OPC UA server needs to be able to be the server and client. Why the second post? Edited 19 Dec 2019 by Gambit Share this post Link to post Share on other sites
Posted 20 Dec 2019 (edited) Well the picture would be the normal setup. But in your case if the OPC UA server is also a client than they would be able to comm between them Server A with Client B Server B with Client A Edited 20 Dec 2019 by Gambit Share this post Link to post Share on other sites
