Daikin FWECSA - write multiple coils and registers - Febiuz - 27.01.2022
Hi everyone,
we've a problem with writing coils and register on a FWECSA Daikin board.
Reading through the classic json profile was good, but writing is not possible.
From the manufacturer's specifications we see the only supported fuinction codes are 15 and 16 , respectively write multiple coils and holding registers.
There is a way to write by json this values or a valid alternative solution ???
Tks in advance for your help

Tks Admin for your help.
Unfortunately I still can't write to coils in multiple mode.
Hope these screenshot could help us to best investigate.
Our goal is to write only the on/off (coil) and setpoint (holding reg.)
Tks again for all

Post your profile. Have you created the device again from scratch after uploading new profile?

What happened in the end? We can't even write via modbus poll. Reads all right

It only supports "write multiple" function. Writing to a single coil or register won't work unless "write multiple" is used.
