"Slave X not responding" means that the communication with slave wasn't successfully created. The reasons can be:
- wrong communication parameters (baudrate, parity, ...)
- wrong wiring
- wrong Slave ID (slave address)
...
Do you have any working example with the controller using a 3rd party software for modbus communication? Just to be sure that the parameters are correct.

]]>The log says "MBDRV: Slave 1 not responding (item='probes')".
The -1 offset was me just trying different things to see if I could trick it to work..! I had tried 0 zero offset we no joy.
Slaves address is 1

]]>I don't see any issue. What does the System log say? Is there any error regarding Modbus communication?
I noticed you specified the Modbus addresses with -1 offset in REXYGEN, am I right? Did you try not to use the offset and configure the mapping according to the datasheet?
What is the Slave address?

]]>I'm having trouble getting the Modbus on the Monarco Hat to communicate to a specific controller. I can't see where I'm going wrong and all wiring is correct, so i assume my register map is incorrect. Project enclosed, Modbus register address doc is also in the folder.
Just wondering if anyone can see anything obvious.
Cheers
