Hi all,
I’m new to mappView and therefore followed the getting started which you can find in the help.
I’m able to open the visualization (see image below) but not any tag is shown. when i check the logger i get the following errors (see image below).
the strange thing is that when my colleague opens my project at his laptop, everything is working fine.
I already tried several port numbers without any luck.
I hope anyone can help me out.
Hello and welcome to the Community,
Try connecting to the OPC UA server with UaExpert.
Hello Niek,
the OPC UA server is used to exchange process variables between the PLC and the mappView visualization. If mappView visualization opens in the browser then the mappView port is ok. The logger indicates that the mappView Server can’t connect to the OPC UA server so the tags don’t work. If the same project with the same settings works fine for your colleague on other PC then sounds like it’s a local issue. Try changing the port on which the OPC UA Server is started from 4840 to something else (for example 4841) - maybe some other program is using/blocking this port on your computer.
In Automation Studio 4 you can do that in PLC Configuration → OPC-UA System → Network Settings → Port number
In Automation Studio 6 you can do that in Configuration View → Connectivity → OpcUaCs → UaCsConfig.uacfg → Network → TCP Port number
If you change the default port on which the PLC starts the OPC UA Server then you’ll also need to change the target OPC UA Server to which the mappView Server tries to connect when it starts. You can do that by adding a “OPC UA remote server configuration file” (OpcUaServer.uaserver) from Toolbox to Configuration View → mappView folder and change the target OPC UA Server port number there.
