Terminating Resistance Status: IR 95

Error Log
The error log records errors that occur in the Controller Link Unit and the time
they occur. The error log can be read or cleared by using Programming
Devices, such as the Controller Link Support Software, the CX-Net, or Sup-
port Software for the CPU Unit (SYSMAC Support Software), or by using the
message service (FINS commands for the Controller Link Unit.)
9-3-1
Error Log Table
Errors are recorded in an error log table in the Unit’s RAM, with one record for
each error and a maximum of 64 or 39 records.
Errors of significance are also recorded in the Unit’s EEPROM so that when
the power to the Unit is turned OFF or reset, a record of the error will remain.
(The error log table in EEPROM automatically reads the Unit’s RAM when the
power is turned ON again.)
Note
The maximum number of records that can be stored in EEPROM is 39.
Network parameter error
(IR 19000) is 1: ON
The CPU Unit’s EEPROM
data link tables or the net-
work parameters are cor-
rupted.
Refer to
and reset the
data correctly. If the error
occurs again, replace the
CPU Unit.
Either set the EEPROM
Clear Bit in the DM Param-
eter Area to ON, or use the
Initialize network parame-
ters operation on the Main-
tenance Menu of the
Controller Link Support
Software to initialize the
network parameters and
then cycle the power sup-
ply.
There is an error in the net-
work parameter settings, or
node address of the local
node is larger then the
maximum address set
within the network parame-
ters.
Refer to
and reset the
network parameters or the
node address.
