Modbus Illegal Data Value - Ian@GWTi - 20.09.2022
Hi,
I have an error in modbus. (write failed: Illegal Data Value) when writing to the register. Reading works fine.
{
"name": "Machine On/Off",
"address": 1280,
"bus_datatype": "bool",
"datatype": "uint16",
"type": "register",
"writable": true,
"value_bitmask": "0x8"
},
Any ideas would be apricated.
Thanks

Add "write_bitmask": true,
