cfffuong Posts: 3 Rating: (0)	Hi everybody, Can anyone help me? When I did WinCC Unified V18 as OPC client connecting to Kepserver as OPC server, got a few problems. Some tags lost connection to the OPC server, some tags didn't. I have checked my OPC server and the tags are still working fine. Sorry for my bad english ! Thank !

However, it does not hurt to review the manual: V18 Unified manual - WinCC Unified OPC UA client On the other hand, I would recommend updating both the TIA Portal (engineering software) and the Unified PC V18 (Runtime) to the latest Update available. Below are the download links: Updates for STEP 7 V18, S7-PLCSIM V18 and WinCC V18 - Update 1 Updates for SIMATIC WinCC Unified PC Runtime V18 - Update 1 SR2
	A rating will be well appreciated.
