Problem with function 16 in Spacelynk modbus - Kilogica - 23.03.2022
Hello,
I'm trying to control a Hidew DOS dehumidifier via Modbus, I made this profile:

}Something strange is happening:
I have a Modbus TCP bridge (Z-KEY by Seneca) and 3 modbus devices, everything is working fine but when I try to write a holding register (with write_multiple set to true as the manufacturer recommend) it doesn't work. For example, I can read this register, but I can't write it.
Code:
{ "name": "Set umidità relativa",
"bus_datatype": "int16",
"address": 0,
"type": "register",
"write_multiple" : true,
"writable": true,
"units": " %"
},I tried with Modscan and everything works fine, also all the coils are managed correctly from Spacelynk...only write holding registers function seems broken.
Any ideas?

Try adding "datatype": "int16" to the mapping entry.

thanks, it works!
