Java PakBus® Software Development Kit

clock set/check, data collection, or sending a file. Each has a

corresponding client interface which will receive status notifications as the

transaction progresses and a completion notification when the transaction

is complete. An application initiates transactions by creating specific

transaction objects and “adding” them to the appropriate datalogger object.

All of the other classes in the API are designed as “helper” classes for the core

classes mentioned above.

2. Setting up the Network

Setting up the API consists of creating an instance of the Network class. This

class has one constructor which requires a PakBus® address, an input stream,

and an output stream. The PakBus® address must uniquely identify your

application in the PakBus® network in which it will participate. The input and

output streams can be derived from an instance of java.net.Socket or of

javax.comm.CommPort. They could also be derived from some other

communications API supported on your platform. The network object will

listen for incoming messages on the input stream object and will write outgoing

messages to the output stream object. Once the network object has been

created, the application must drive it by calling its check_state() method

periodically. All notifications and activity in the network will result from this

call. The following code fragment shows an example of constructing and

driving a network object:

import com.campbellsci.pakbus.*;

import java.net.*;

class Example2

{

private Network network;

private Socket socket;

private boolean complete;

public void run() throws Exception

{

socket = new Socket("192.168.4.225",6785);

network = new Network(

(short)4079,

socket.getInputStream(),

socket.getOutputStream());

complete = false;

while(!complete)

{

network.check_state();

Thread.sleep(100);

}

The application shown above doesn’t do much of interest to anyone. It will

accept, but not act on most incoming messages. But, at this point, it is pretty

much useless to us. This can be changed somewhat by adding station objects

to the network. Consider the above example expanded:

1 2 ... 5 6 7 8 9 10 11 12 13 14 15 ... 29 30
