Write set value of BOOL directly to hardware

Write set value of BOOL directly to hardware

Hi all,

I am trying to solve an error in Zenon for one of our machines. When loading a recipe, via a reaction matrix a function is called. The last function in the script of this called function is to reset a BOOL to FALSE, through a Write Set Value with the selection to write it directly to hardware.

In one of our versions this value is not written to the PLC, but for another version where the functions and scripts are identical it does work. When I do not write directly to hardware, but change it to a Dialog I can change the BOOL to FALSE.

Does anyone know why writing directly to the hardware fails?

Thanks in advance!
