WinCC Unified Connection OPC UA
With the new version of WinCC Unified, for now we have three types of connections for our PLC.
Here we can see the different drivers, today we are going to try the OPC UA, as it would allow us to connect another type of PLC that is not Siemens. Did you know that you can create an OPC UA server to, for example, have it on a PC, where it acquires data from a card, etc.... Well, that would be another tutorial.
Having selected the driver that interests us, the only thing we need to define is the URL. Here I have defined the URL with the IP address, but in some cases, you need to specify the name.
If we want to use the embedded discovery here, where it specifies <<Add new Computer>>, we need to define the name of the PC, just the name!!!, but here we will not be able to explore the server.
This is when we define the variables that interest us, where we are going to explore the Server.
We just need to use the tags where appropriate and simulate our process to transfer to Runtime :-)
