12.5.1 How to execute the maintenance commands

To execute via Modbus communication
There are two types of execution methods. Use them selectively in accordance with the intended use.
z
Write "1" to data (Recommended)
Write "1" to data, and when the data changes from "0" to "1," the command is executed.
When executing the same command again, once return to "0," and write "1." It can be used with safety because the
command is not executed consecutively even if "1" is continued to write from the master controller.
z
Write "2" to data
If "2" is written to data, the command is executed. It will automatically return to "1" after the execution. The data can be
written consecutively because of no need to be returned to "0."
If commands which take time to write to the non-volatile memory such as "Write batch NV memory" command are
executed consecutively, increase the length of the intervals between commands.
Only the "Alarm history details" command is an exception. Write the alarm history number to be checked with the
"Alarm history details" of the monitor command.
The following maintenance commands may not be completed at the time of sending the response.
To check that a command is completed, check that the SYS-BSY has been turned from ON to OFF.
