“Variable ‘<name>’ in the variable configuration isn’t updated in any task”

The top level instance of the variable is not referenced by a call in any task. Thus it will not be copied from the process image.

Example:

Variable Configuration:

VAR_CONFIG

END_VAR

plc_prg:

index := INDEXOF(aprg);

The program aprg is referenced but not called. Thus plc_prg.aprg.ainst.in never will get the actual value of %IB0.
