Unable to access data on a Vista OPC Server that reside on Xenta Server (I/NET or 3rd Party protocols)

Issue

When adding points to your OPC Client from a Schneider Electric Vista OPC Server that contains points from Xenta Servers error "The item definition does not conform to the server syntax".

Environment

Vista 5.x

Vista OPC Server 1.6.x

Xenta Server 511-B, 731, 527, 913

Cause

There are certain characters that are invalid in an OPC Server environment which are allowed in the Vista Server database.

Invalid names include I/NET, RS232/485 A, and TCP/IP.

Resolution

Create a folder in the Vista database and create shortcuts for the points that are suffering this problem. This avoids any invalid characters, but grants full functionality for the data in question.
