F ACTIVE (OK)
OFF ON Normal indication, Node Adapter

ON ON/OFF Node adapter board not properly
initiated, probable cause:
- Board faulty
- Incorrect I/O-type parameter
ON/OFF OFF No communication with host
processor, probable cause:
- Incorrect parameters for RIO-
board
- Incorrect wiring
- Host processor fault
ON/OFFBLINK Bad Communication, probable
cause:
- Host Processor in Program
mode
- Reversed connections
The RIO board is a wide board taking up two I/O slots.
When this board is configured it is always in the left of
the two slots being occupied by this board.
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.
