Thank you diat150 for your respond.
I tried MatrikonOPC Explorer on the Ignition Gateway machine for connection to our PLC host with PLC vendor’s OPC Server.
It connected immediately (only entered host IP address and name of the OPC Server), but when attempting to add Tags popup error window appeared:
[b]"An error was encountered while communicating with this server.
The server will be disconnected and no further communication
attempts will be made. To prevent dicsonnection, show details.
The error may indicate a non-compliant server.
If the problem persists, contact the server vendor."
“[Name of the OPC Server] caused COM/OPC error 0x8001011B on IConnectionPoint.Advise()
Error string: Unknown error.
Additional: Could not establish data callback connection on group ‘Group1’
Interface address is 0x00B5D1EC
Vendor detail: [Vendor Company Name and Address]”[/b]
When I ignored the error popup window, everything works and I can add all Tags and see live data in MatrikonOPC Explorer pane, seems that everything works OK.
UPDATE: We managed to connect Ignition to the PLC’s OPC Server this way:
- enter not only OPC Server Name, but also CLSID (maybe Ignition then overrides some Win7 DCOM security settings and allow for incoming “data” from remote OPC Server? - don’t know).
Is there some way not to specify CLSID (GUID) and make connection to remote OPC Server DA2 from Windows7/Ignition Gateway? I mean OPC Server directly in PLC.
