Digital Output - Motor Relay 41
Note:
One of the three motor contact relay output
must be mapped as a contactor (value 1
thru 5).
When any motor contact relay is mapped as
a contact then the rest of the output relays
can be treated as a signal output and set to
any value.
Signal output can be dual mapped (first byte
mapped to operation1, and 2nd byte mapped
to a different operation)
Example of mapping output 3 as a signal
output relay
Identification Feedback Status = 23 (first
byte)
Main Contactor 2 Feedback Status
Flashing = 38 (second byte)
Convert 3823 to HEX = 0x0EEF.
Convert 0x0EEF to decimal - 3823
Place 3823 in the output 3 register
Note: second byte has the highest priority
when both are present
