Hi Nursultan Check the follow issues: 1. Are the computer in work group or domain. If the computer are in a work group the windows user from the server station must be also user in the client station and the windows user from client station must be user from server station. The windows user from client station must be in admin group of the server station 2. Pleas check the DCOM settings on bot computers if the opc server and client are on different computer. Which DCOM settings must be checked for WinCC (V7 and Professional) with OPC DA if the connection between server and client does not work? https://support.industry.siemens.com/cs/ww/en/view/109768431 Why can you no longer connect the WinCC OPC DA Client to third-party servers after upgrading to WinCC V7.3? https://support.industry.siemens.com/cs/us/en/view/109483815 3. Are the settings of firewall correct? For testing switch of the firewall. If you use any router open the ports Ports für DCOM (135,445) Start the Simatic Security Control and repeat the settings. Restart the computer 4. Please check with OPC-Scout from Simatc Net or any other OPC_Client if the OPC connection works SIMATIC NET: Industrial Communication Commissioning PC Stations - Manual and Quick Start https://support.industry.siemens.com/cs/ww/en/view/13542666 Best regards schufri |

Dear schufri, Thanks again for your time. About points listed: 1. Both computers on workgroup named "Workgroup " 😄 no problem there. 2. The DCOM settings are alright. 3. Generally, firewall is switched off. However, the router needs configuration I guess. Also, could you tell more about Simatic security control? 4. I am checking the connection with Matrikon application, it's working fine. Best regards, Nursultan Nurzhanuly |
