PLC’s CPU Unit error is 1:
ON
Communications 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.
The relevant node is not in
the Network.
A communications error
has occurred as a result of
noise.
A communications error
has occurred.
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.
Enter the node in the Net-
work.
Conduct an echoback test
using the Controller Link
Support Software and if
this does not correct the
error, check the usage
environment.
Refer to page 274 Trouble-
shooting with RUN, ERC,
ERH and INS Indicators
and troubleshoot accord-
ingly.
