Error Error definition and causes
code
D245H The target station number of the dedicated
instruction is incorrect.
D247H When the dedicated instruction was
executed, response from the target station
was received twice.
D249H The target station CPU type of the dedicated
instruction is incorrect.
D24AH The arrival monitoring time specification of
the dedicated instruction is incorrect.
D24BH The number of resends specified in the
dedicated instruction is incorrect.
D24CH The network number specification of the
dedicated instruction is incorrect.
D24DH The channel specified in the dedicated
instruction is incorrect.
D24EH The target station setting in the dedicated
instruction is incorrect.
D24FH The dedicated instruction was executed
when the station number/IP address of the
own station had not been set yet.
D251H • At execution of a dedicated instruction, or
group specification or all stations
specification of the target station, the
execution type is set with arrival check.
• For the REQ instruction, the specified
request type is incorrect.
Action
• Execute the instruction again after correcting the target station number at
the request source of the dedicated instruction.
• If the request source is on another network, check if "Routing Settings" of
CPU parameters are set correctly, and take action.
• Check the network status using the CC-Link IE TSN/CC-Link IE Field
diagnostics of the engineering tool, and take action.
• Check if the switching hub and the Ethernet cables at the request source
are connected properly.
• If the request source is on another network, check if "Routing Settings" of
CPU parameters are set correctly, and take action.
• Execute the instruction again after correcting the CPU type of the target
station at the request source of the dedicated instruction.
• If the request source is on another network, check if "Routing Settings" of
CPU parameters are set correctly, and take action.
• Execute the instruction again after correcting the arrival monitoring time at
the request source of the dedicated instruction.
• When the own station, target station, or relay station detected an error,
identify the cause of the error and take action.
• Execute the instruction again after lower the transient transmission usage
frequency.
• Check if the switching hub and the Ethernet cables at the request source
are connected properly.
• Execute the instruction again after correcting the number of resends at
the request source of the dedicated instruction.
• When the own station, target station, or relay station detected an error,
identify the cause of the error and take action.
• Execute the instruction again after lower the transient transmission usage
frequency.
• Check if the switching hub and the Ethernet cables at the request source
are connected properly.
• Execute the instruction again after correcting the network number at the
request source of the dedicated instruction.
• If the request source is on another network, check if "Routing Settings" of
CPU parameters are set correctly, and take action.
• Set 1 to 2 for the target channel number in the control data when
executing the SEND instruction.
• Set 1 to 32 for the channel number when executing the REMFR/REMTO/
REMFRD/REMTOD instruction.
• Execute the instruction again after correcting the channel number used by
own station in the control data.
• The value set for the control block of the dedicated instruction is out of
range. Execute the instruction again after correcting the value.
• If the error occurs again even after taking the above, please consult your
local Mitsubishi representative.
• Specify the station number/IP address using the UINI instruction, and
execute the instruction again.
• If the error occurs again even after taking the above, please consult your
local Mitsubishi representative.
• Execute the dedicated instruction again after changing the execution type
in the control data to no arrival check.
• For the REQ instruction, execute it again after correcting request type.
• If the error occurs again even after taking the above, please consult your
local Mitsubishi representative.
