Notes:
1. I:000/00 is any application related conditioning logic.
2. MG20:0.EN is the “enabled” status bit from the message block.
3. B3/2 is a one-shot and causes the message to be resent each time the
message block completes or errors (as long as I:000/00 is true).
4. The DF1 address of the PLC-5 is the same as its DH+ address (set by
dip switch SW1 on the PLC-5).
5. Refer to Publication 6200–6.4.11, Instruction Set Reference, for
information on the MSG block.
6. Refer to Publication 1785–6.6.1, Hardware Installation Manual, for
information on configuring the PLC-5 Channel 0 hardware.
7. Refer to Publication 6200–6.4.6, Software Configuration and
Maintenance, for information on configuring the PLC-5 Channel 0
driver.
8. Only one message may be active to a Communications Module at any
time. This requirement must be ensured by the PLC program written by
the user.
