[HELP] modbus config

[jdevoo]

Describe the issue I have a modbus server started on the LAN, port 5020 and I use the configs below for the GW

thingsboard:
  host: localhost
  port: 1883
  security:
    accessToken: some_token

storage:
  type: memory
  read_records_count: 100
  max_records_count: 100000

connectors:
  -
    name: Modbus Connector
    type: modbus
    configuration: modbus.json

modbus is configured with the following file

{
  "server": {
    "host": "192.168.1.109",
    "port": 5020,
    "devices": [
      {
        "unitId": 1,
        "deviceName": "fio_server",
        "sendDataOnlyOnChange": false,
        "attributes": [
          {
            "tag": "at_entry", "type": "bits", "functionCode": 1, "objectsCount": 1, "address": 1
          },
          {
            "tag": "at_exit", "type": "bits", "functionCode": 1, "objectsCount": 1, "address": 2
          }
        ],
        "rpc": [
          {
            "tag": "entry_conveyor", "type": "bits", "functionCode": 5, "objectsCount": 1, "address": 0
          },
          {
            "tag": "buffer_conveyor", "type": "bits", "functionCode": 5, "objectsCount": 1, "address": 1
          }
        ]
      }
    ]
  }
}

When i launch the gateway though, the modbus config is causing troubles with a NoneType - see below

Hi @jdevoo,

It is an issue with docker image, could you try to download the latest image from dockerhub and try again?

@zbeacon @jdevoo I apologize for not related with the topic in advance. My question is what's the most used modbus server, is it a hardware component or a software emulation library like EasyModbusTCP.NET ?
