0x800401F3 DCOM Error

Symptom

The usual symptom is an inability for an OPC client to establish an initial connection with the OPC server.

 

Cause

0x800401F3 is an error that occurs when the function CLSIDFromProgID is unable to determine an OPC Server Class ID (CLSID) from the given Program ID (ProgID). The ProgID is used to identify the name of an OPC server. This is usually due to the fact that the OPC server fails to correctly register itself.

 

Repair Procedure

If the OPC server installation was performed correctly during the setup, you have to register the OPC server as follows to fix this problem:

  1. In the Windows search box, enter Run.
  • The Run dialog box displays.
  1. Enter the name of the Desigo CC OPC server with the complete path (for example, [Installation Drive]:\[Installation Folder]\GMSMainProject\Bin\[company name].Gms.OPCServer.exe) or drag the file from Windows Explorer.
  1. After the OPC server name, enter –RegServer.
  1. Click OK.
