FX5U 4034H — Device specification error
Warning — monitor
CAUSE
Why does it occur?
• The dedicated instruction cannot be executed since the completion device for the dedicated instruction does not turn on.
REMEDY · Step by step
How to fix it?
• Since the completion device for the SREAD or SWRITE instruction does not turn on in the CPU module on the target station, execute the instruction again after setting the operating status of the CPU module on the target station to the RUN status.
Do not reset repeatedly before identifying the cause. Repeated resets while ignoring a trip/alarm can cause secondary damage (IGBT failure, motor winding damage, etc.).
