[jpnordexpert]

Hello, i have a problem with An Idegis equipment DOM-24. I can read all without problem but it is imposible to write to it.

This is the mapping
{
  "manufacturer": "Idegis",
  "description": "Dom-24",
  "mapping": [
    { "name": "Alarma Caudal", "bus_datatype": "bool", "type": "discreteinput", "address": 16 },
    { "name": "Alarma Baja salinidad", "bus_datatype": "bool", "type": "discreteinput", "address": 17 },

    { "name": "Consigna Producción", "bus_datatype": "uint16", "type": "inputregister", "address": 7, "units": "%" },
    { "name": "Resulta test de sal", "bus_datatype": "uint16", "type": "inputregister", "address": 8, "units": "mV" },
    { "name": "Consigna producción W", "bus_datatype": "uint16", "type": "register", "address": 38, "writeable":true, "write_multiple":true}

The last line is where is the problem. I don`t know what is wrong?

the desciption of the Idegis only allows to write multiple coil and multiple register.
