Hi OziOzi Are you sure you have followed the steps for creating and adding the remote OPC user to SIMATIC HMI user group on your local OS so that DCOM will work? You might need to adjust other DCOM settings as well on the 3rd party system as is normal for OPC DA. |
If my post helped you, please rate. Thanks. |

There is a lot of information on OPC DA and DCOM also available in the WinCC Forum it is mostly all applicable obviously since WinCC is used in PCS7. You can start with these articles, should hopefully get you working or closer: Why are the DCOM settings of the WinCC OPC server reset after activating the OS Runtime? After that, you might have to restart machines and if its still not working you will have to dig deeper into other DCOM config settings which may be custom to your 3rd party OPC Server. |
