Program Description
RUNG000 comprises of a Manual input which may be a toggle button or sensor output by which operation is
performed.
Until I:1/0 is pressed, JMP does not energize, that means program is being scanned rung by rung and it
does not affect program or process at all.
When I:1/0 is pressed, program is directly jumped to the LBL and scans RUNG004.
If Sensor Input I:1/4 is true, it energizes O:2/3 turning ON Output 3.
As long as JMP is energized, all the output between JMP and LBL rungs are skipped and Input I:1/1 to I:1/3
do not affect O:2/0 to O:2/2 at all.
Important thing to note here is that if Latch Output is used between JMP-LBL rungs and is active then it is
not unlatched when JMP energizes.
