Modbus register type

Hello,

I am fiddling with a UIO20E, with the intention of configuring it as outputs.

I have the mapping like this.

Code:

{
  "manufacturer": "Indomogal",
  "description": "Universal 16+4 I/O module",
  "mapping": [
    {
      "name": "Output 1",
      "bus_datatype": "1",
      "type": "coil",
      "address": 0,
      "writable": 1,
      "value_custom": {"0": "Off", "1": "On"}
    },
    {
      "name": "Output 2",
      "bus_datatype": "bool",
      "type": "coil",
      "address": 1,
      "writable": 1,
      "value_custom": {"0": "Off", "1": "On"}
    },
    {
      "name": "Output 3",
      "bus_datatype": "bool",
      "type": "coil",
      "address": 2,
      "writable": 1,
      "value_custom": {"0": "Off", "1": "On"}
    },
    {
      "name": "Output 4",
      "bus_datatype": "bool",
      "type": "coil",
      "address": 3,
      "writable": 1,
      "value_custom": {"0": "Off", "1": "On"}
    },
    {
      "name": "Output 5",
      "bus_datatype": "bool",
      "type": "coil",
      "address": 4,
      "writable": 1,
      "value_custom": {"0": "Off", "1": "On"}
    },
    {
      "name": "Output 6",
      "bus_datatype": "bool",
      "type": "coil",
      "address": 5,
      "writable": 1,
      "value_custom": {"0": "Off", "1": "On"}
    },
    {
      "name": "Output 7",
      "bus_datatype": "bool",
      "type": "coil",
      "address": 6,
      "writable": 1,
      "value_custom": {"0": "Off", "1": "On"}
    },
    {
      "name": "Output 8",
      "bus_datatype": "bool",
      "type": "coil",
      "address": 7,
      "writable": 1,
      "value_custom": {"0": "Off", "1": "On"}
    },
    {
      "name": "Output 9",
      "bus_datatype": "bool",
      "type": "coil",
      "address": 8,
      "writable": 1,
      "value_custom": {"0": "Off", "1": "On"}
    },
    {
      "name": "Output 10",
      "bus_datatype": "bool",
      "type": "coil",
      "address": 9,
      "writable": 1,
      "value_custom": {"0": "Off", "1": "On"}
    },
    {
      "name": "Output 11",
      "bus_datatype": "bool",
      "type": "coil",
      "address": 10,
      "writable": 1,
      "value_custom": {"0": "Off", "1": "On"}
    },
    {
      "name": "Output 12",
      "bus_datatype": "bool",
      "type": "coil",
      "address": 11,
      "writable": 1,
      "value_custom": {"0": "Off", "1": "On"}
    },
    {
      "name": "Output 13",
      "bus_datatype": "bool",
      "type": "coil",
      "address": 12,
      "writable": 1,
      "value_custom": {"0": "Off", "1": "On"}
    },
    {
      "name": "Output 14",
      "bus_datatype": "bool",
      "type": "coil",
      "address": 13,
      "writable": 1,
      "value_custom": {"0": "Off", "1": "On"}
    },
    {
      "name": "Output 15",
      "bus_datatype": "bool",
      "type": "coil",
      "address": 14,
      "writable": 1,
      "value_custom": {"0": "Off", "1": "On"}
    },
    {
      "name": "Output 16",
      "bus_datatype": "bool",
      "type": "coil",
      "address": 15,
      "writable": 1,
      "value_custom": {"0": "Off", "1": "On"}

    }
  ]
}

In principle it works correctly, since I get voltage at the outputs.

But in registers, I get this: Modbus (RTU 1 slave 1) read failed: Illegal data value.


I installed a 120 ohm resistor, so I saw in another post, before installing it it gave me more errors.
