SA(210) in AC0020 When subchart ST0400
(i.e., the subchart with step ST0400) is active,
SA(210) changes the status of ST0500 in the subchart
to execute status. (Subchart ST0400 is executed
while ST0130 is active.)
SP(211) in AC0020 SP(211) changes the status
of ST0500 to pause.
SR(212) in AC0020 SR(212) changes the status
of ST0500 back from pause to execute.
SF(213) in AC0020 SF(213) changes the status
of ST0500 to halt. Execution of action AC0500 will
continue because it has an “S” AQ.
SE(214) in AC0500 SE(214) changes the status
of ST0500 to inactive. Execution of action AC0500 will
continue because it has an “S” AQ.
SOFF(215) in AC0500 SOFF(215) changes the sta-
tus of ST0500 to inactive. The action in the step is
stopped and reset even though is has an S-group AQ.
