Configuring and Interfacing
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.
Refer to Publication 1785–6.6.1, Hardware Installation Manual,
for information on configuring the PLC-5 Channel 0 hardware.
Refer to Publication 6200–6.4.6, Software Configuration and
Maintenance, for information on configuring the PLC-5 Channel
0 driver.
Only one message may be active to a Serial Communications
Module at any time. When you write the PLC program, you must
ensure this requirement.
