JMP plc shows tutorial for you to inspect out and learn more about plc programs
PLC shows JMP and LBL instructions
Often in plc shows you wish to control how the plc scanner acts. You may desire to enable it to relocate to various portions of the ladder diagram. For this we use JMP and LBL. LBL enables us to label a specific sounded left wing and hand side and JMP allows us to define a label which we want to jump to. This is extremely much like how it operates in assembly language. It is essential to keep in mind that any rung which has a label and does not include some kind of jmp guideline somewhere might never ever be carried out. So these rungs generally will be totally ignored. It's always great practice to try and avoid this scenario as jmp and lbl can make your ladder program truly untidy and hard to debug if things are jumping around all the time.
