LD: confusion between FB input and global variable

LD: confusion between FB input and global variable

Summary

In zenon Logic, the global variable is used instead of the local parameter in certain constellations in the Ladder Diagram (LD). This has been fixed.

Description

In zenon Logic, a user-defined function block has an input parameter. This has the same name as a global variable. The user-defined function block was programmed in the LD language. The compiler in the LD diagram takes the values of the global variables instead of the values of the local input parameter.

This error has been fixed. Now, as expected, the value of the local input parameter is used.

To benefit from this fix:

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