Error Code List (Continued)
Error No. Description of error Corrective action
FD08 Send failure (in the case of bus)
Check for the coaxial cable connection and its loose, the connection
of terminating resistors, and the cable faults.
FD09
Loop status change in the middle of the operation
(offline loop test)
Retry a test. (Do not switch the loop in the middle of the operation.)
(If the error frequently occurs, check the line and the wiring status.)
FD0A Unstable communication (offline loop test)
Retry a test.
(If the error frequently occurs, check for faulty cables, faulty
hardware, noises, absence of terminating resistors (in the case of
bus), and incorrect wirings.)
FD0B Wiring error (offline loop test) Check the wiring.
FD11 Error occurred during test execution Execute after the completion of the test from other stations.
FD12 Disconnecting error Review the cause for why the station is being disconnected.
FD13
Station number error
The online diagnostic is executed by parameter
designation during no parameter receiving.
The online diagnostic is executed with station
number is lower than host station number with
station number designation.
Set the total number of link stations with a common parameter.
Set the station number that is equal to the host station number or
larger.
FD1A Station with a duplicated station number Check the duplicate station number, and correct it.
FD1B Test abort error
The ongoing test was interrupted due to the resetting of the test
executing station.
Fix a faulty station on the networks.
FD1C Interruption error due to loop switching during test
Retry a test. (Do not switch the loop in the middle of the operation)
(If the error frequently occurs, check the lines and the wiring status.)
FD1E Bus topology, test disabled error Perform a test that can be executed in the bus topology.
FD31
Duplicate online diagnostics request error
(The online diagnostics error is outputted at the same
time)
Execute another online diagnostics again after one is completed.
FD35 Response wait timeout
FD36 Action wait timeout
FD38 Duplicate message error
Retry after a little while.
Check the status of the relevant station and of the line.
FD39 Host station is test requested (communication test) Change the test request destination.
FD3A
Communication test request destination error
(communication test)
A station to which a test request is not available was specified.

FE20
Data error
(Received data cannot be processed. Other than
AnUCPU is designated as relay station.)
Correct the routing parameters, or replace the relay station with
AnUCPU.
FE21 ZNRD/ZNWR device range error Review the device range of the target CPU module.
FE22 Request error Data length error of general data, etc.
FE23 Message error
Retry.
(If the error frequently occurs, check for the faulty cables, faulty
hardware, noises, absence of terminating resistors (in the case of
bus), and incorrect wirings.)
FE24 CPU error occurred
Review the installing of the CPU modules and network modules,
and retry.
FE25 Base power supply error
Confirm the power supply status (insufficient voltage, instantaneous
interruption, overvoltage, etc.) of the target station for transient
transmission and the relay station.
