RS485 ON A16

[tom_elec]

Hello everyone,

I recently bought a Kincony A16 card with the aim of making it work in RS485 with this Waveshare gateway :
https://www.amazon.fr/dp/B09LQMH2S1?ref=...title&th=1

I control this gateway from a Loxone Miniserver, however I can't really understand the Kincony Modbus register table :
https://kincony.com/forum/attachment.php?aid=2240

The loxone page for modbus communication :
https://www.loxone.com/frfr/kb/communication-modbus/

RS485 transmission is enabled in the A16 and gateway parameters.

I need the I/O address and the register type.

Could someone tell me the requests to send to enable / disable an output and get state of digital / analog input on A16 please ?

Thanks in advance for your help, Tom

here is KCS firmware modbus protocol document: https://www.kincony.com/forum/showthread.php?tid=2528
the register address begin with 0, you can check with protocol.
if you integrate to Loxone Miniserver, suggest use our new controller F16 or B16M, it's very easy for integration by UDP command, they support KCS v3.

Hello, I have been trying to start modbus communication between kincony A16 and EastronSDM630 (https://www.eastroneurope.com/products/v...m630modbus) via rs485 using espHome for some time, according to the documentation the registers are identical to kincony. 

Log file shows: [17:53:08][D][modbus_controller:040]: Modbus command to device=1 register=0x64 no response received - removed from send queue

I would like to ask if I have something wrong in the .yaml file:
