We are trying to use a remote OPC server with Ignition via an OPC-DA COM Connection. The remote server is running RSLinx. I was originally able to connect to the remote server successfully, however we could not actually obtain data from any of the PLCs. After searching through the forum, i thought that it could be the CLSID needed curly braces around the number, and after editing this i was unable to connect to the remote server again - even after changing the settings back and re-adding the server to Ignition.
I have gone through and fixed the DCOM security settings, as per the MatriconOPC “Establishing OPC Communication on Windows XP SP2 and Windows 2003 SP1” guide from their site as was recommended in another thread. This is not been able to fix the issue either.
The error code we are getting is:
com.jniwrapper.win32.com.ComException: COM object method returns error code: 0x8007000E; E_OUTOFMEMORY (Not enough storage is available to complete this operation.)
So there are two issues (or maybe fixing one will fix both):
[ul][li]We can not connect to the remote server[/li]
[li]When we can connect, we can not obtain data from it[/li][/ul]
Thank you for any help with this issue.
EDIT: I forgot to mention that we are currently running version 7.0.4 (b4594).
