![]() ![]() And in project 2, Client connects to PLC, then send data to Server.Īnd if so, is there any difference in the configuration? For example, in project 1, I connect the PLC to Client, are there any changes I need to make it work? So as I understand, the roles of Server and Client in those 2 projects are reversed, right? I mean in project 1, Server connects directly to PLC, why Client access data through Server. In the one I asked above, the problem is that: the client writen by C# has to read data from PLC, then send it to Cloud.And because of the OPC UA connection, the client laptop can display data, and also send some control signal to PLC. Then I got a PLC, connect it to the PLC Server laptop, so that the Server read and write data from and to PLC. I have done a project: using Citect SCADA as SCADA software, 2 laptops as Server and Client, and using Kepware to config an OPC UA connection between them. ![]() It's quite ridiculous, I think, but I don't really understand about how the system work. This console client should connect to the KepServer if you give it the proper URL:Īnd thank you very much for the sample program above, it's much easier for me to carry out my project now. ![]()
