    8.10 Instructions  Programming instructions • Since the buffer memory data of the master station is kept transferred (refreshed) to/from the inverters, the TO instruction need not be executed every scan in response to data write or read requests. The execution of the TO instruction every scan does not pose any problem.

    The following diagram shows the system configuration with one inverter. The diagram indicates how the cause of the fault can be checked with the LED status of the inverter communication option (FR-A8NC). (In this example, assume SW, M/S, and PRM LEDs of the master module are OFF (master module is in normal operation).)
