Hello all, We are in the process of doing final pre-deployment testing on a PCS7 V9.1 SP2 UC04 system and recently came across Windows Application event viewer errors on 2x OS redundant servers and 1x ES station, both of which are running Windows Server 2019. We have a mixed number of other Server 2019 and Windows 10 machines, but they are not showing these errors. The computers are generating OPCF Bonjour Service, EventID 100, "Cannot create another system semaphore". The errors happen at different time of day/night, while the project is running but no one is even accessing the machines. We were able to find an Entry ID on the forums: How do you disable the "OPCUA Local Discovery Server" service for WinCC V7 and Wi... - ID: 109749461 - Industry Support Siemens but its associated products are TIA Portal and WinCC, rather than PCS7. By following this article we can disable the OPCUA and stop these errors, but this is just a workaround with unknown implications. If anyone has suggestions to potential solutions, or implications of following this article in PCS7 then please advise. Thank you for any assistance. |
