- Board faulty
- Incorrect I/O-type parameter
ON/OFF OFF No communication with host

The serial I/O interface, DSQC 239 (RIO), is intended
to be used for communication with Allen-Bradley PLC
equipment. The board is equipped with 32 yellow LEDs
(which indicate the status of the first 16 inputs and
outputs on the front panel), a red F-LED and a green
LED, "ACTIVE".
If the green LED is not lit and the red one goes OFF, the
board's special communication circuit is probably faulty.
If replaced, there are no adjustments or procedures
required.
