The BECKHNG Driver do not import the Variables from the .tpy File

The BECKHNG Driver do not import the Variables from the .tpy File

Summary

Changes in the TPY file format can lead to circular references in the BECKHNG driver. Variables with circular references cannot be imported. 

Description

The BECKHNG driver refuses to import variables from the TPY file. This happens because of a changed TPY file format from TWINCAT version 3.1.4024.20 to 3.1.4024.22 that leads to circular data type references.

This circular reference is now resolved:

  • If a circular reference is detected, the import stops at this point for this structure. The variable is not imported. A LOG entry is written. 
  • Then the process continues with the next variable. 
  • All variables that can be imported are imported. 
  • For all other variables this LOG entry is created:  “File is not valid! Sub-Datatyp” <xxxxxxxxx> already exits in this structure <xxxxxxxxx>."

To take advantage of this fix:

  • Update to the latest build of zenon 8.20 or later
