Contoh Pengunaan

Buat file tags.js yang berisi address list :

module.exports = [{
    "name": "A",
    "address": 40100,
    "eu": "MT/Hrs",
    "description": "",
    "hi": "",
    "lo": "",
    "type": "real"
  },
  {
    "name": "B",
    "address": 40102,
    "eu": "C",
    "description": "",
    "hi": 120,
    "lo": 90,
    "type": "real"
  },
  {
    "name": "C",
    "address": 40104,
    "eu": "Toor",
    "description": "",
    "hi": 200,
    "lo": "",
    "type": "real"
  },
  {
    "name": "3A",
    "address": 30000,
    "eu": "Toor",
    "description": "",
    "hi": 200,
    "lo": "",
    "type": "real"
  },
  {
    "name": "3B",
    "address": 30002,
    "eu": "Toor",
    "description": "",
    "hi": 200,
    "lo": "",
    "type": "real"
  },
  {
    "name": "3C",
    "address": 30012,
    "eu": "Toor",
    "description": "",
    "hi": 200,
    "lo": "",
    "type": "real"
  },
]

Buat konfigurasi device pada file devices.js

module.exports = {
    PLC1: {
        name: 'PLC1',
        host: '192.168.1.1',
        update_interval: 500,
        base_address: 0,
        swap_byte: true
    },
    PLC2: {
        name: 'PLC2',
        host: '192.168.1.2',
        update_interval: 500,
        base_address: 0,
        swap_byte: true

    }
}

Kemudian, buat file utama dengan nama app.js

var modbus = require('i6-driver-modbus.');
var _ = require('lodash');

// Berisi tags / address list
var tags = require('./tags.js');

// Berisi konfigurasi device
var devices = require('./devices');

devices.PLC1.tags = tags;
devices.PLC2.tags = tags;

var PLC1 = new modbus(devices.PLC1);
var PLC2 = new modbus(devices.PLC2);



PLC1.on(PLC1.events.valueUpdate, (payload)=>{
    _.each(payload.tags, function(tag){
        console.log(tag.name +  ' : ' + tag.value);
    });
});



PLC2.on(PLC2.events.valueUpdate, (payload)=>{
    _.each(payload.tags, function(tag){
        console.log(tag.name +  ' : ' + tag.value);
    });
});
