OPC Server Issues with Lookout 6.1

[JBlaser]

Hello All,

I have an application, using Lookout V 6.1.  I have copied the files from a Lookout V 6.0 application that all ready works.  The Lookout package is communicating using the Helmholz Step 5/Step 7 OPC Server to a Siemens S7-414H processors (a redundant system).

The previous application worked fine, but it was done by another engineer who is no longer with our company.  The new application, I keep getting the following message:

"PC/OLE error (1): Configuring OPC server (10): The item ID is not defined in the server address space or no longer exists in the server address space. (C0040007): Item (PRO1.HMI.PCV_PB_CLOSE_12)."

I have checked this item out using the Helmholz OPC Test Client, the tag does exist inside the PLC and the OPC Test Client can read the data just fine, however Lookout does not appear to be communicating with the OPC server.

Any help would be greatly appreciated.  Like I said, I can get the OPC Test Client to communicate, but not the Lookout project.

Thanks for the help.

Best Regards,

Have a look at the OPCClient object, as well as some expressions on the panel in the previous application. Did the previous application use any customized Access Path for the items like the attachments?

Also try "Flat", instead of "Hierachical" for browsing option. After you change to Flat, refresh the object in Object Explorer.
