pyxiscloud commented 8 years ago

Hello I've tried to create slave

in this case it working: `'use strict';

var log = console.log; var mb = require('modbus').create();

mb.onError(function (msg) { log('ERROR', msg); });

// create device memory map var data = mb.createData({ countReg: 5, countBit: 2, countInputReg: 4, countInputBit: 2, }); data.setReg(2, 321); data.setBit(1, true); data.setInputReg(1, 123); data.setInputBit(0, true); data.dumpData(); // show memory map

// create slave device var ctx = mb.createSlave({

// connection type and params con: mb.createConTcp('192.168.10.17', 502),

// data map data: data,

// callback functions onQuery: function () { log('onQuery'); }, onDestroy: function () { log('onDestroy'); } });`

in this case it's not working: `'use strict';

var log = console.log; var mb = require('modbus').create();

mb.onError(function (msg) { log('ERROR', msg); });

// create device memory map var data = mb.createData({ countReg: 5, countBit: 2, countInputReg: 4, countInputBit: 2, }); data.setReg(2, 321); data.setBit(1, true); data.setInputReg(1, 123); data.setInputBit(0, true); data.dumpData(); // show memory map

// create slave device var ctx = mb.createSlave({

// connection type and params con: mb.createConTcp('localhost', 502),

// data map data: data,

// callback functions onQuery: function () { log('onQuery'); }, onDestroy: function () { log('onDestroy'); } });`

i've tried also change localhost to "127.0.0.1" - it stil not working

Hi! I'll test it as soon as possible, but I have some code like yours, and it works. Probably, you need to switch port to 1502 or run it with sudo, because, as I know, ports < 1000 not allowed for non-sudo users.

Hi, i've tested with sudo and 1502 port. still the same - not working (

pyxiscloud commented 8 years ago

Fix it - changed to '0.0.0.0' and it open port for all connection (not only from localhost)

Sorry, gmail thought that the letters from the github is spam =/ Something really strange - probably it is error in your system - I can't reproduce this bug. Not for localhost <-> localhost, nor for localhost <-> different PC
