Hello
Have problem with communication between Wago PLC and SCADA software through CoDeSys OPC DA.
PLC is programed in CoDeSys v2.3.9.61, OPC DA server is installed from CODESYSV35SP10Patch2.
The problem is that after a few weeks communication stops working and can't automatically rebuild. Killing manually process WinCoDeSysOPC.exe helps to rebuild communication. I noticed that when communications works process WinCoDesysOPC.exe, day by day increasing sligtly memory consumption and stops working when reach about 2GB (screen in attachement).
When problem exist, I am seeing also in CoDeSys log (C:\ProgramData\CoDeSysOPC) such errors:

How can I could fix this problem? Thank you for any suggestions

Did you find the solution for this issue? i'm having the exact same issue with a new machine at the moment....

Yes. I bought license and installed latest CoDeSys OPC DA version.
