Hi Mikhail,

Sorry to bother you again. It seems that my OpcEnum configuration has been changed once more. The connection is working fine now.

Best regards,

Hi Mikhail,

I am performing the same task with another OPC DA server running on a different machine.

DCOM configuration has already been completed.

Using the “MatrikonOPC Explorer” OPC DA client, I am able to successfully connect to the remote OPC DA server. However, when attempting to access the server using Rapid SCADA, I encounter an error: “CoCreateInstanceEx denies access.”

Both machines have installed the following components:
OPC Core Components Redistributable (x64) 3.00.108
OPC Core Components Redistributable (x86) 3.00.108

Could you please advise on how to resolve this issue?
Thank you very much for your help in advance. Wishing you a great day!

Best regards,
Jiujing Xu

Hi Mikhail,

Thanks a lot for your reply. My DCOM configuration was reset by accident. I’ve now managed to get everything working again.

Many thanks for your support and guidance.

Best regards
