MODBUS - Can't write on registers
#1
Hi,

I created the attached modbus profiles for a fancoil. I CAN READ but I CAN'T WRITE on the holding registers (from 26301 to 26327).
What is wrong?

Thanks

Peppe

Incorrect spelling: not writeble but writable

Ooops.... that's embarassing! Smile
i did the fix, but i still can't write to the logs.
Yet with a modbus tool software I can write in the registers, but in the 0x10 mode: write multiple registers, as reported in the pdf manual.

The script in the post - I suppose should be put as init script - refers to a tcp modbus connection... I have an RTU. re
And how I can map the registers to knx addresses?

The suggestions is to use "write_multiple": 1 in your profile
