I am using a 1769-L33 ERM CompactLogix 5333 Controller.
how long does an energized coil stay on after the routine that the coil is
in stops execution?
In this case the coil is used to stop the JSR to it.
--------[ not error]----------------------JSR A ->called first
------- ------------------------------------JSR B -> called 2nd
many other JSR's are executed here.........
Subroutine A
------[valve did not open]--------------------------( error) -> not latched, it is an OTE
Subroutine B
--------[error ?]-------------------------------------(set system fault)
I know the answer is usually one scan. Is one scan the beginning of the
ladder to the end of the ladder. The JSR occurs first in the sequence of execution, then Subroutine B, then a bunch of other routines. Will the error coil still be energized when Subroutine B is executed?
