5.3 CONTROL BYTES FOR OPTO 22
The OPTOMUX APB Setup Bytes, PLC Control and Status Bytes, Digital I/O Control Bytes, and
OPTOMUX Analog I/O Control Bytes are presented in Tables 5-1 through 5-4. If any Control
Byte is changed during operation, it takes up to 10 seconds to become effective (there is a
10 second interval between PCS checks for setup changes.)

fault
Mode It indicates the APB communications functionality as
follows:
0 = Off, 2 = OPTO 22 Mode
This datapoint should be left at 0 and configured to
a 2 after all of the other control bytes are
configured because setting this datapoint causes
the OPTO-22 PLC Interface functionality to start.
