Action
• Execute the link dedicated instruction again after
correcting the target station number.
• When specifying another network station, check if the
settings in "Routing Setting" of "CPU Parameter" are
made correctly.
• Execute again after correcting the command code at
the request source.
• If the request source is on another network, check if
the routing parameters are set correctly, and take
action.
• Execute again after correcting the used channel within
the allowable range at the request source.
• If the request source is on another network, check if
the routing parameters are set correctly, and take
action.
• Correct the transient data at the request source, and
retry the operation.
• If the error occurs again even after taking the above,
please consult your local Mitsubishi representative.
• Correct the transient data at the request source, and
retry the operation.
• If the error occurs again even after taking the above,
please consult your local Mitsubishi representative.
• Check the network status and take corrective action

• Check if the switching hub and the cables at the
request source are connected properly.
• If the request source is on another network, check if
the routing parameters are set correctly, and take
action.
• Execute link dedicated instruction again after changing
the execution type in the control data to "No arrival
acknowledgment".
• For the REQ instruction, execute again after correcting
request type.
• 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.

REQ instruction.
• If the problem cannot be resolved with the above
actions, the possible cause is a hardware failure of the
module. Please consult your local Mitsubishi
representative.
Change the channels used by own station or the target
station's channel in the control data.
• Execute again after correcting the device specification
for the ZNRD/ZNWR instruction.
• If the problem cannot be resolved with the above
actions, the possible cause is a hardware failure of the
module. Please consult your local Mitsubishi
representative.
• Execute again after correcting the device specification
for the ZNRD/ZNWR instruction.
