I’ve been using the OPC UA server for months now with a virtual controller setting up communications. Today I’m getting error messages “Error creating monitored item on server.” I tried updating the OPC UA server and RobotStudio. Using Softing DataFEED client as the manual recommends. Any ideas?
Uninstalled and reinstalled everything. It’s working now!
Good day! I have been using virtual controller IRC5 and OPC-UA server in RS2021 actively for the last few months. This is a task for students to do connection with UAExpert client. We have a lot of issues for controller tags of Rapid variables and I/O signals not showing up on the opc client side. Usually this works only after several re-starts and recreation of robot alias in the server.
Is this somewhat related to the virtual controller? Othervise this is a production-like setup.
Thanks for sharing your issue and updating. I’m trying the IOT Gateway against an older version of robotware (6.05.02) and only get PERS variables (no VAR or CONST) – perhaps I need to try some re-installs.
Hello,
user_matiss After creating a persistent variable on the controller, you have to restart the IoT Gateway for it to show up in the client. Same goes for when you delete a variable from the controller.
XNOR According to the manual https://robotapps.blob.core.windows.net/apps/ApplicationManual%20IoT%20Gateway%20v1.1.pdf:
I.e. only persistent variables are available from the RAPID domain.
