Example
Here's one example of a configuration file for the Modbus Master module, dxmodmast.json

{
    "servers": [{"url":"127.0.0.1:1883"}],
    "project": "DEM0",
    "id": "mbus",

"meta": {
        "name": "dxmodmast"
    },

"task": [
        {
            "enable": true,
            "id": "stn1",
            "url": "127.0.0.1",
            "trigger": 1000,
            "watchdog": 5000,
            "stationId": 1,
            "readOnly": false,
            "data": [
                { "$csv": "dxmbusmast.csv" }
            ]
        },
        {
            "enable": true,
            "id": "stn2",
            "url": "127.0.0.1",
            "trigger": 2000,
            "watchdog": 8000,
            "stationId": 2,
            "readOnly": true,
            "data": [
                { "$csv": "dxmbusmast.csv" }
            ]
        }
    ]
}

And the associated CSV, note that the same CSV file is being linked in two different configuration groups.

disable,name,desc,address,type,length,default,scale,addressEx
false,"AO001","this is description",1,"int16",-1,1,10,"4"
false,"AO002","this is description",2,"int16",-1,1,10,"4"
false,"AO003","this is description",3,"uint16",-1,1,1,"4"
false,"AO005","this is description",5,"int16",-1,1,100,"4"
false,"AO006","this is description",6,"uint16",-1,1,10,"4"
false,"AO007","this is description",7,"int16",-1,1,1,"4"
false,"AO008","this is description",8,"uint16",-1,1,"4"
false,"AO009","this is description",9,"uint16",-1,1,1,"4"
In this example, the first tag for group 1 & 2 shall be "gateway1.stn1.AO001" & "gateway1.stn2.AO001" respectively.

If you have IGX installed on one machine, you may use this sample of dxmodmast.json and dxmodmast.csv files to push the collected Modbus data to IGX server with IO-hub enabled as specified in "server": "127.0.0.1:1883".

You may then start off the DX Modbus driver by just opening the command prompt console and typing "dxmodmast" at the current directory where both JSON+CSV files are located.
