When the first data link status word is set to the default (0000) for either the
manually set data link tables or automatically set data link tables (In the first
data link status word parameter), the data link status is stored in the above
area (CIO 1500 + 25 × (Unit No.) (+ 7 to +22)).
When a different area has been set for the first data link status word, the sta-
tus is stored in the specified area. The status storage format is the same as
the one shown in the above diagram.
PLC’s CPU Unit error is 1:
ON
Bit status
Remaining receive area
0: Not remaining
1: Remaining
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.
