Error after receiving the data

[ghost]

Hi,

I am receiving the intended output from the modbus library but after each data received I am getting the following output: data <Buffer 30 31 30 33 30 39 30 31 30 33 30 34 37 46 46 46 46 46 46 46 64 32 36 37 34 63 35 61> error from serial in { '0': { err: 'Timeout', message: 'Request timed out' } }

I am concerned with the error timeout.

This is the following code that I have written: let modbus = require('jsmodbus') let SerialPort = require('serialport') var host = '/dev/ttyS2'; var options = { baudRate: 19200, parity: 'none', stopBits: 1, dataBits: 8 }; console.log("connecting to", host, options); let socket = new SerialPort(host,options);

let client = new modbus.client.RTU(socket, 1)

socket.on('close', function () { console.log("close", arguments) })

socket.on('open', function () { console.log("socket on open"); client.readHoldingRegisters(200, 40) .then(function (resp) { console.log("resp", resp) socket.close() }).catch(function () { console.error("catch", arguments) socket.close() }) })

socket.on('data', function () { console.log("data", arguments) })

socket.on('error', console.error)

Is this a library issue or any fault in my code ? Please resolve.

Seems to be related to #224

Can you start your application with env DEBUG=* and post the output. And please use some formatting when you post code.

Here is the output for the same: Please Find attachment. debug_Output.txt

Like the debug message is saying

Data has been received but could not be interpreted correctly (not enough data available). I haven't had time to look into the byte data, feel free to do so. Maybe they are using ASCII Mode or Modbus/TCP over RTU which is not supported in this module. Could be that your device manual can tell you something about it.
