Motion in SCL or keep it in ladder so maintenance can still read it?
The question
S7-1500, two axes, cam table. SCL is cleaner. The night tech reads ladder. If I hide the motion in an FB with a ladder wrapper, is that a peace treaty or a mess?
TS ControlsThe answer
Peace treaty. Motion math in SCL inside an FB. Interlocks, permissives, and the 'why is it stopped' bits in ladder on the face of that FB. Comment the in/out. Night shift should not have to parse a cam polynomial at 2 a.m. They should see the permissive that is false.
