95u - Condition for Arithmetic Operations in LAD

Hi plcspace

don't have Step5 handy, but attached Step 7 logic example will functionally do in LAD what your S5 STL logic does and you are hopefully able to program it in Step 5.

UPDATE:

Bad news, Step5 does not allow a conditional call of the "Move" instruction (aka L/T instruction in Step5) so the above Step7 logic can not be directly translated into Step5. All up, simplest way is to stick with STL.
