Error Error definition and causes
code
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.
D843H The module operation mode is set to a
mode in which transient transmission
cannot be executed.
D844H Incorrect frame was received.
• Unsupported pre-conversion protocol
• Unsupported frame type
• Application header variable part
• Application header HDS
• Application header RTP
• Read command not requiring response
D902H The online test data is incorrect.
D903H During execution of the communication
test, the test was retried.
D905H A communication monitoring timeout has
occurred in communication test.
D906H Data sending completion wait timeout has
occurred in communication test.
D909H The header information of transient
transmission is incorrect.
D90AH During execution of the communication
test, the test was retried.
Action
• Write the network parameter to the CPU module again.
• Execute the instruction again after correcting the 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 the 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.
After completion of the module communication test, retry the transient
transmission.
Execute the instruction again after correcting the request data at the
transient request source.
• Correct the data at the station that started the online test, and retry the
operation.
• If the error occurs again even after taking the above, please consult your
local Mitsubishi representative.
After completion of the communication test, retry the operation.
• Check the network status using the CC-Link IE TSN/CC-Link IE Field
diagnostics of the engineering tool, and take action. Then, retry the
operation.
• Check if "Routing Setting" of "CPU Parameter" is correctly set, 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. Then, retry the
operation.
• Execute the instruction again after lower the transient transmission usage
frequency.
• Check if "Routing Setting" of "CPU Parameter" is correctly set, and take
action.
Execute the instruction again after correcting the header information at the
transient request source.
Check the network status using the CC-Link IE TSN/CC-Link IE Field
diagnostics of the engineering tool, and take action. Then, retry the
operation.
