Xybernetics Wonderware - Unable To Open InTouch Application In WindowViewer

The source of this error is normally due to the existance of file “xtagnam.$$$”. The “xtagnam.$$$”” file is generated for the replication of “tagname.x” file and is used for NAD support (InTouch 7.1 and Later).

This error will pop up if your Wonderware application is running somewhere… maybe on another RDP session. Note that this file will not be created when you run the WindowsViewer using WindowMaker first. However, if you run the WindowViewer without opening the application in WindowMaker first this file will be created. If you shut down your running Windowviewer in that RDP session will remedy this problem.

Alternatively, your NAD process could have been stuck somewhere. In that scenario, you will have to undeploy all running InTouch managed applications on the terminal server node and delete the xtagnam.$$$ file and redeploy.

“tagname” File Anatomy
The definations are from “TechNote 145 – FactorySuite and ArchestrA InTouch® Application File List”.

“tagname.x” is a binary file for storing Tagname Database for the InTouch application. The backup has the extension .XBK and is created after a dbload is performed on the application. this file can be found in “C:\Program Files (x86)\ArchestrA\Framework\Bin\“”

“xtagnam.$$$” is a replication of the tagname.x created when an application is opened in WindowViewer without opening the application in WindowMaker first (Introduced with InTouch 7.11). This file is used by the Runtime database for the definition/configuration of the tagname dictionary. WindowViewer requires this file if there is no tagname.x (if the application is not first opened in WindowMaker). This file can be found in “C:\Program Files (x86)\ArchestrA\Framework\Bin\
