Moxa I/O

This interface is a Java interface for controlling a MOXA device. The Moxa.java file is used for the Moxa ioLogik E1200 Series Remote I/O devices. There are 11 different product configurations for the ioLogik E1200 series.

• E1210
• E1211
• E1212
• E1213
• E1214
• E1240
• E1241
• E1242
• E1260
• E1261
• E1262

Disclaimer:

All examples for this library are abstract. The final design pattern of how the methods in this library are used is completely up to the developer of the project (you).

Moxa Documentation

Since this device is an electrical component, please read the documentation about the device before starting to work with it.

Installation

Place this file in your /src/project/package directory to get started. Once it is placed it is rather simple to use.

Usage

Initialize the device:

 Moxa mx;                            // use somewhere that the instance of the class can be accessed

 mx = new Moxa();                    // provides path to driver
 int initStatus = mx.initDevice();   // initializes socket for device communication

Connecting to a device:

connectToDevice( String ipaddress, String password )

The connection should be made with the existing Moxa class instance (mx).

  int handle = mx.connectToDevice("10.0.0.22", "myPassword");

Multiple handles can be made with the help of a loop. Here we use an ArrayList and iterate through them. Again, please come up with your own specific data structures that will suit your project.

  public List<String> ipAddresses = new ArrayList<>();                
  public List<Integer> handles = new ArrayList<>();

  for(int i=0;i<ipAddresses.size();i++){
    handles.add( mx.connectToDevice( ipAddresses.get(i) ,  "myPassword" ) );
  }

Reading Digital Inputs:

readDI( int connectionHandle, byte channel, byte count )

This will read DI 0 of device 100001.

  int result = mx.readDI(100001, (byte) 0, (byte) 1 );

To read multiple channels simply change the count parameter to how many channels you want to monitor.

Reading Digital Outputs:

readOutput(int connection, byte slot, byte channel)

This will read DO 2 on slot 0 of device 100001.

  int result = mx.readOutput( 100001, (byte) 0, (byte) 2 )

Writing Digital Outputs:

writeOutput(int connection, byte channel, byte count, int value)

Turn the output on:

  int result = writeOutput( 100001, (byte) 0, (byte) 1, 1 );

Turn the output off:

  int result = writeOutput( 100001, (byte) 0, (byte) 1, 0 );

Read Analog Inputs:

readAnalogChannel( int connection, byte channel, byte count )

Reads analog voltage on AI 1:

  double result = mx.readAnalogChannel( 100001 , (byte) 1, (byte) 1 );

Disconnect Device

disconnect(int connection)

Disconnects device 100001

  mx.disconnect( 100001 );

Exit Device

exitDevice()

  mx.exitDevice();
