When the Read Holding Register 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:

Data		Coil Status
	OFF to ON		ON to OFF
Change data (high order)	FFh		00h
Change data (low order)	00h		00h

An example follows (note that to command the inverter, set A002=03):

•Sending a RUN command to an inverter having slave address “8”

•This example writes in coil number “1.”

Query:

1	Slave address *1	08
2	Function code	05
3	Coil start address *2	00
	(high order)
4	Coil start address *2	00

Response:

No.	Field Name	Example
		(Hex)
1	Slave address	08
2	Function code	05
3	Coil start address *2	00
	(high order)
4	Coil start address *2	00
	(low order)
5	Change data	FF

6	Change data	00
	(low order)
7	CRC-16 (high order)	8C
8	CRC-16 (low order)	A3

Note 1: No response is made for a broadcasting query.

Note 2: The PDU Coils are addressed starting at zero. Therefore coils numbered 1-31 are addressed as 0-30. Coil address value (transmitted on Modbus line) is 1 less than the Coil Number.

When writing in a selected coil fails, see the exception response.
