Note:
Do not add normal coil after WAIT instruction in XD/XL series PLC sequence
BLOCK, and add XD, XL series PLC special signal SEM bit(SEM0~SEM31); SEM cannot
be controlled by set or reset. It can only be set by POST instruction and reset by WAIT SEM
instruction. Or output via OUT instruction. The difference between them is that the POST
command needs to be triggered by the pulse edge to keep the state of SEM; the OUT
command needs to be triggered by the normally open coil, and the SEM is reset when the
triggering condition is disconnected.
