Error Error definition and causes
code
D253H A response timeout has occurred when
the dedicated instruction was executed.
D254H A dedicated instruction which the target
station does not support was executed.
D255H The target station number of the dedicated
instruction is incorrect.
D256H The execution or error completion type of
the dedicated instruction is incorrect.
D257H The request type of the REQ instruction is
incorrect.
D258H The control station did not exist when the
dedicated instruction was executed to the
specified control station or current control
station.
D25AH The dedicated instruction was executed
with a channel in use specified.
D25BH The dedicated instruction was executed
with a channel in use specified.
D25DH The transient data is incorrect.
Action
<When using the Simple Motion mode>
• Check the network status using the CC-Link IE TSN/CC-Link IE Field
diagnostics of the engineering tool, and take action.
• For the IP address specification, it is not possible to target stations beyond
a relay station. Execute the dedicated instruction by specifying the network
number/station number.
• Execute the instruction again after increasing the number of resends at the
request source of the dedicated instruction.
• Execute the instruction again after lowering the transient transmission
usage frequency.
• When "Dynamic Routing" in "Application Settings" is set to "Enable",
check the 'Communication path determination status' (Un\G2860544 to
Un\G2860559) and check if communication to the target network number
is possible.
• Execute the dedicated instruction for a target station that supports the
executed dedicated instruction.
• For the RECV instruction, execute it again after correcting the own station
storage channel in the control data.
• For the RECV instruction, check that 'RECV execution request flag CH1'
(SB0030) to 'RECV execution request flag CH8' (SB0037) are on.
• For the SLMPSND instruction, execute it again after checking if the
destination port number set in the control data is the available port number
using the manual of the external device.
• Correct the network number and station number/IP address of the target
station of the dedicated instruction.
• Check if the Ethernet cable is connected properly.
• For the REMFR/REMTO/REMFRD/REMTOD instruction, increase
'REMFR/REMTO instruction resend count' (SW001A) or 'REMFR/REMTO
instruction response wait timer time' (SW001B) at the request source and
try again.
• If the request destination is for another network, check if the CPU module
serving as the relay station supports the routing settings, and take
corrective actions.
• If the error occurs again even after taking the above, please consult your
local Mitsubishi representative.
• Change the target station at the station that executed the SEND
instruction.
• If the error occurs again even after taking the above, please consult your
local Mitsubishi representative.
• Execute the instruction again after correcting the target station number in
the control data.
• If the error occurs again even after taking the above, please consult your
local Mitsubishi representative.
• Execute the instruction again after correcting the execution or error
completion type in the control data.
• If the error occurs again even after taking the above, please consult your
local Mitsubishi representative.
• Execute the instruction again after correcting the request type in the
request data.
• If the error occurs again even after taking the above, please consult your
local Mitsubishi representative.
• Execute the instruction again after correcting the target station number in
the control data.
• If the error occurs again even after taking the above, please consult your
local Mitsubishi representative.
• Retry the operation after a while.
• Change the channels used by the own station or the target station storage
channel in the control data.
Change the channels used by the own station or the target station storage
channel in the control data.
• Execute the instruction again after correcting the transient data at the
transient request source.
• If the error occurs again even after taking the above, please consult your
local Mitsubishi representative.
