link. Confirm that the Local Data Link Active Bit is ON before referencing the
data link status.
When the first data link status word is not set or is set to the default (0000) for
either the manually set data link tables or automatically set data link tables,
the data link status is stored in the following words for nodes 1 to 6 only.
PLC’s CPU Unit error is 1:
ON
Bit status
1: Local node data link participating
0: Local node data link not participating or data link
Remaining receive area
0: Not remaining
1: Remaining
inactive
Insufficient (short) receive area
0: Sufficient
1: Insufficient
Offset error
0: Normal
1: Error
A fatal PLC error, non-fatal
PLC error, or a watchdog
timer error has occurred.
The Unit is mounted to a
non-compatible PLC.
Data link participation
0: Not in data link or data link inactive
1: In data link
Probable cause
Communications error (data link reception)
0: Normal
1: Error
PLC's CPU Unit error
0: Normal
1: Error
PLC status
0: Inactive (user program not running)
1: Active (user program running)
Error: Offset exceeds
number of send words.
Remaining: Receive
area is larger than send
area. Data is received
and remaining words
are cleared.
Insufficient: Receive
area is smaller than
send area. Excess data
is truncated; other data
is received.
Refer to the PLC’s opera-
tion manual and correct
the error. If the error occurs
again, replace the PLC.
Refer to 1-2-4 Controller
Link Unit Models and PLCs
and mount onto the correct
PLC.
