Action
No action is required because the system performs a retry.
However, if the error occurs frequently, check for cable failure, hardware
failure, noise, and wiring error.

Correct the routing parameter or change the relay CPU module to the one
supporting the MELSECNET/10, such as AnUCPU or QnACPU.
Correct the range of the access target device of the ZNRD/ZNWR
instructions to be sent to ACPU.
With the engineering tool, check if an access to another station was
executed in the CPU module with a different project type.
Please consult your local Mitsubishi representative.
Check the status of the CPU module of the target station and relay station.
Or, change the corresponding CPU module.
Check the power supply status of the transient transmission target station
and relay station. (Check for voltage shortage, momentary power failure,
and overvoltage.) Or, change the corresponding CPU module.
Check the operating status (such as a watchdog timer error) of the CPU
module of the target station and relay station. Or, change the
corresponding CPU module.
