06 (0x06) Write single register
A slave holding register is changed (rewritten).
If broadcast (0) is specified, all slave holding registers of the same address are rewritten.
To request, specify the holding register address and change data.
Example) Change the moving average filter (address 40009) value to 20 (0x0014).
Keep in mind that the relative address for writing in the moving average filter is 0x08.
In the case of normal writing, the response becomes identical to the request.
15 (0x0F) Write multiple coils
On slave coils, data is changed by the specified number of coils from the specified address.
If broadcast (0) is specified, all slave coils of the same address are rewritten.
To request, specify the coil address and the number of bytes and output value to change.
* N = Number of coils/8 or N = N + 1 if indivisible
