*1: Depends on the CPU’s operating state. The RUN LED is lit while the CPU is in operation; the RUN LED is unlit while the CPU is not in operation.

*2: Depending on the settings of the operating parameters from the peripherals, the operation may be continued even when an error occurs.

*3: Although batteries cannot be mounted on the 10- or 14-point type, battery errors are monitored by the system. Set R7EE to OFF prior to the use.

*4: Supported by software version 1.11 (WRF051=H0111) or newer.

How to Clear the CPU Error Code:

Set 1 to the Special Internal Output R7EC.
