# Source\_in

![source\_in node in AXV\_datasource section](https://2909878411-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-Lc00kv6JMggJXSZbUet%2F-LdgGNBKyB7rIfTWFfp1%2F-LdgIsuPlRq3y1ivQIV6%2Fsource_in.PNG?alt=media\&token=ec995dd9-6953-4443-87cd-16ff26bb26df)

## Introduction

This node allows you receive data form system or connected devices (such as Modbus sensors, PLC, etc.)

## System information

`source_in`allow you get DIO status, General information, HWM result and IO status from device `AXView`

### DIO status

You can get the digital input/output status in your computer by choosing sensor DIO, also, it'll show the pin define of GPIO. (**1** means input, **0** means output)

## Receiving Modbus devices data

After create a device and setup the parameters of Modbus, AXView 3.0 will start auto polling, so you can get data of Modbus device by using `source_in` node, too.

![](https://2909878411-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-Lc00kv6JMggJXSZbUet%2F-LeuE3q_yoMODC5WgnZC%2F-LeuG6o8Sh5J15-bqdOA%2Fimage.png?alt=media\&token=ac6be38d-7ef6-44a7-a865-34fd0ebd7612)

If you connect the `source_in`to `debug` node, it will shows the result of polling. By default, the data format are always hexadecimal in string, if you want to know the result of decimal, you have to transform it by using `function`node.

The code in the `function` node "Hex to Dec":

```javascript
msg.payload = parseInt(msg.payload, 16);
return msg;
```

After transformation process, you'll get a decimal in number result.
