I have a problem with the communication of the ctrlX CORE PLC App with WinStudio via OPC UA.
With default settings communication is established correctly, (without encryption). Browse variables also works well. But when I map the variable, and put on the screen, I don't see the value update but only ??????. The reading counter doesn't change either. However, the publishing works fine.
As far as I understand, subscription mode doesn't work for me.
Because if I add a trigger, e.g. BlinkFast, the reading starts working, but it behaves strangely. Sometimes ?????? symbols will appear, or variables fall into exchange loops.
Is there an option to establish communication using a subscription?
ctrlX CORE RM22.11
PLC App, OPC UP,... v18
HMI VR3 WinStudio(IndraWorks 14V22 P12) - I don't use indraworks v15 because Latest WinStudio Remote Agent has a problem with custom windows shell.
Thank you in advance for your help!
