Notes:
•
I:000/00 is any application–related conditioning logic.
•
MG20:0.EN is the enabled status bit from the message block.
•
B3/2 is a one-shot that causes the message to be resent each time
the message block completes or errors (as long as I:000/00 is
true).
•
The DF1 address of the PLC-5 is the same as its DH+ address (set
by DIP switch SW1 on the PLC-5).
•
Refer to Publication 6200–6.4.11, Instruction Set Reference, for
information on the MSG block.

Only one message may be active to a Serial Communications

ensure this requirement.
