Compiler crashes when parsing a LD program

Compiler crashes when parsing a LD program

Description

zenon Logic is terminated unexpectedly when building an LD program. The cause is the handover of a two-dimensional array to a UDFB that expects a one-dimensional array as input. This cannot work and leads to an error. It is expected that this error is displayed.

This behavior has been changed. zenon Logic is no longer terminated unexpectedly. The program remains open and, as expected, a corresponding error message is displayed.

To benefit from this fix:

  • Update your zenon Software Platform to the latest build of zenon 14 or higher.
