Hello folks,
I am a rookie, self-training in PLC programming.
I have written an SFC exercise (attached ACD file). I also try to call STL written subroutines and add-on instructions, from within the SFC main program.
Calling the created subroutine works fine, but calling the add-on instruction fails from a reason which is above my level. I tried, tried and tried different solutions, with no avail. I am either wrong in writing the add-on (perhaps some missing but missing tag ?), or wrong is calling it.
Can someone please give me a hint on what I do wrong ?
Thank you, Radu
PS . I use Studio 5000 v24, combined with RSLogix 5000 Emulator.
