Error Error definition and causes
code
D653H Parameter error (transient transmission
group setting)
D654H Parameter error (dynamic routing setting)
D655H Network addresses of the master station and
slave stations are incorrect.
D656H Parameter error (CANopen communications)
D657H Parameter error (station sub-ID)
D658H Parameter error (multidrop number)
D659H Parameter error (CANopen communication)
D65AH Parameter error (maximum number of
connectable stations)
D65BH Parameter error (CC-Link IE TSN Class
setting)
D65CH Parameter error (TSN hub setting)
D65DH Parameter error (multiple period setting)
D840H Number of transient requests exceeded the
upper limit of simultaneously processable
requests.
D841H The request data size of memory read/write
command is out of range.
D842H • Routing information to the destination
network number is not registered.
• In transient transmission, the number of
relays to other networks exceeded seven.
• The communication path is being updated.
Action
• Write the network parameter to the CPU module again.
• Execute the instruction again after correcting the transient transmission
group setting in the setting data.
• If the error occurs again even after taking the above, please consult your
local Mitsubishi representative.
• Write the network parameter to the CPU module again.
• Execute the instruction again after correcting the dynamic routing setting
in the setting data.
• If the error occurs again even after taking the above, please consult your
local Mitsubishi representative.
Correct the IP address setting of the master station or slave stations.
Update the version of the engineering tool that supports the CANopen
communication function, then write parameters to the CPU module again.
• Write the network parameter to the CPU module again.
• If the error occurs again even after taking the above, please consult your
local Mitsubishi representative.
• Write the network parameter to the CPU module again.
• If the error occurs again even after taking the above, please consult your
local Mitsubishi representative.
The CANopen communication function cannot be used. Clear the PDO
mapping setting in the engineering tool, and write the parameter to the CPU
module again.
• Parameters are set over the maximum number of connectable stations.
Correct the parameter so that the number of slave stations is 120 or less,
then write parameters to the CPU module again. Note that a PDO-
mapped extension module (for example, a multi-axis servo amplifier) to
which a station number is not set is counted as one station.
• If the error occurs again even after taking the above, please consult your
local Mitsubishi representative.
• Write the network parameter to the CPU module again.
• Execute the instruction again after correcting "CC-Link IE TSN Class
Setting" in the setting data.
• If the error occurs again even after taking the above, please consult your
local Mitsubishi representative.
• Write the network parameter to the CPU module again.
• Execute the instruction again after correcting "TSN HUB Setting" in the
setting data.
• If the error occurs again even after taking the above, please consult your
local Mitsubishi representative.
• Write the network parameter to the CPU module again.
• Execute the instruction again after correcting "Multiple Period Setting" in
the setting data.
• If the error occurs again even after taking the above, please consult your
local Mitsubishi representative.
• Execute the instruction again after pausing the transient transmission
temporarily.
• Execute the instruction again after lower the transient transmission usage
frequency.
Execute the instruction again after correcting the read or write size
specification at the transient request source.
• Execute the instruction again after correcting the target network number
at the transient request source.
• Execute the instruction again after correcting the communication path
from the transient request source to the destination.
• When the dynamic routing is not used, or the module of the series other
than MELSEC iQ-R is included, retry the operation after correcting the
routing setting.
• Change the system configuration so that the number of relay stations is
seven or less.
• Transient transmission cannot be performed while the communication
path is being updated. Retry the operation.
