ERROR CODE LIST
This chapter shows the codes for errors occurred in the dedicated function library and the corrective actions.
4.1

Common Error Codes

The following table shows the common error codes for the dedicated function library.
*1
Error code Description
Decimal Hexadec
imal
Driver not started
1 0001H
The driver is not started.
Timeout error
2 0002H
• A timeout occurred while waiting for the response.
• During CC-Link communication, the request was issued to
other stations when the station number of the own station is
'64'.
• The module specified as the communication target is not
supported.
66 0042H Already opened error
The specified channel has already been opened.
Already closed error
67 0043H
The specified channel has already been closed.
69 0045H Unsupported function performing error
An unsupported function in the target station was performed.
Station number error
70 0046H
• The specified station number is incorrect.
• The request for other stations was issued to the own station,
or the network number was not '0' even though the station
number was the own station (FFH).
77 004DH Memory reservation error
Resource shortage error
Task over error
• Reserving sufficient memory failed, or there are too many
tasks using the dedicated function library.
• A function other than the C Controller module dedicated
function for the interrupt service routine (ISR) is executed in
ISR.
Network channel number error (When a SEND/RECV request
85 0055H
is issued.)
Channel number error
Data send error
102 0066H
Restart error
Sending data failed, or an attempt was made to send data
during restart.
103 0067H Reception error
Receiving data failed.
Corrective action
• Check the channel number.
• Correct the error that occurred when the driver is started.
• Check the status of the system drive of the C Controller
module.
• Check if the operating system is running normally.
• Review the operating status and mounting condition of the
access target station.
• Retry on the user program.
• Increase the timeout value of MELSEC data link function.
• When issuing a request to other stations during CC-Link
communication, set the station number of the own station
other than '64'.
• Check if the module specified as the communication target is
supported.
The open processing is required only one time.
(If this error occurred, the path of the correct channel will be
returned to the argument.)
The close processing is required only one time.
• Check the path of the channel, network number, and station
number.
• Check if the function performed in the target station is
supported.
Correct the network number and station number specified in the
user program.
• The memory may be insufficient. End another running task or
reduce the access size.
• Check if the C Controller module is running normally.
• Reset the C Controller module, or turn the power OFF and
ON.
• Reduce the number of tasks which use the dedicated function
library and retry the operation.
• To execute other dedicated functions synchronously with an
interrupt, implement the notification processing in a user
program and perform the processing in a task.
• Review the size or number specified to the arguments of the
user program.
Check the specified channel number when the SEND/RECV
request is issued.
• Retry.
• Retry after completion of the restart.
• Check if the C Controller module is running normally.
• Reset the C Controller system.
• Retry.
• Check if the C Controller module is running normally.
• Reset the C Controller module, or turn the power OFF and
ON.
