The data set in the response is as follows:
When the Read Coil Status command cannot be executed normally, refer to the
exception response.
Write in Coil [05h]:
This function writes data in a single coil. Coil status changes are as follows:
An example follows (note that to command the inverter, set A002=03):
• Sending a RUN command to an inverter having slave address “10”
• This example writes in coil number “1.”
