Status Area and Troubleshooting Section 9-2
Other Status
Receive area insufficient
(short) is 1: ON
The send area at the rele-
vant node is larger than the
receive area and some
data cannot be received.
When the intention is not to
receive all data, use as is
(data that cannot be
received will be read and
discarded.)
When it differs from the
intended data link, check
the number of send words
at the relevant node, the
number of receive words at
the local node and the off-
set, then reset the data link
table correctly.
Receive area remaining is
1: ON
The send area at the rele-
vant node is smaller than
the receive area and some
of the area will be unused.
When the intention is to
leave some space in the
receive area, use as is (the
surplus receive area will be
cleared to 0.)
When it differs from the
intended data link, check
the number of send words
at the relevant node, the
number of receive words at
the local node and the off-
set, then reset the data link
table correctly.

Error log exists (IR 19015)
is 1: ON
Error information on the
Controller Link Unit (an
error log) has been
recorded.
Using the Controller Link
Support Software or an
FINS command, read the
cause of the current error.
Alternatively, use past error
log records to troubleshoot
the problem.
Communications controller
send error (IR 19011) is 1:
ON
The Controller Link Unit is
faulty.
Replace the Controller Link
Unit.
Inconsistent network
parameters (IR 19010) is 1:
ON
Indicates that the network
parameters recorded in the
CPU Unit’s EEPROM differ
from the values of the Net-
work in use.
Check the network param-
eters on the Network in
use using the Controller
Link Support Software, and
reset necessary parame-
ters.
Node address duplicate
setting error (IR 19009) is
1: ON
The same node address
has been used more than
once.
Reset so that each node
address is used only once
within the same Network.
EEPROM error (IR 19007)
is 1: ON
An error has occurred
while writing data to the
CPU Unit’s EEPROM.
Check the status of bits
IR 19000 to IR 19002 and
correct any problems
found. If the error occurs
again, replace the CPU
Unit.
