Hello.
I am testing the ListeterTest2.java and works fine.
public class ListenerTest2Mon1 {
static Random random = new Random();
static float ir1Value = -100;
public static void main(String[] args) throws Exception {
ModbusFactory modbusFactory = new ModbusFactory();
final ModbusSlaveSet listener = modbusFactory.createTcpSlave(false);
listener.addProcessImage(getModscanProcessImage(127));
// When the "listener" is started it will use the current thread to run. So, if an exception is not thrown
// (and we hope it won't be), the method call will not return. Therefore, we start the listener in a separate
// thread so that we can use this thread to modify the values.
new Thread(new Runnable() {
public void run() {
try {
listener.start();
}
catch (ModbusInitException e) {
e.printStackTrace();
}
}
}).start();
while (true) {
updateProcessImage1((BasicProcessImage) listener.getProcessImage(127));
synchronized (listener) {
listener.wait(100);
}
}
}
static void updateProcessImage1(BasicProcessImage processImage) {
processImage.setNumeric(RegisterRange.HOLDING_REGISTER, 0, DataType.TWO_BYTE_INT_UNSIGNED,
random.nextInt(10000));
processImage.setNumeric(RegisterRange.HOLDING_REGISTER, 2, DataType.FOUR_BYTE_INT_UNSIGNED_SWAPPED,
random.nextInt(10000));
processImage.setNumeric(RegisterRange.HOLDING_REGISTER, 10, DataType.TWO_BYTE_INT_UNSIGNED,
random.nextInt(10000));
processImage.setNumeric(RegisterRange.HOLDING_REGISTER, 12, DataType.FOUR_BYTE_INT_UNSIGNED_SWAPPED,
random.nextInt(10000));
processImage.setNumeric(RegisterRange.HOLDING_REGISTER, 20, DataType.TWO_BYTE_INT_UNSIGNED,
random.nextInt(10000));
processImage.setNumeric(RegisterRange.HOLDING_REGISTER, 22, DataType.FOUR_BYTE_INT_UNSIGNED_SWAPPED,
random.nextInt(10000));
}
static BasicProcessImage getModscanProcessImage(int slaveId) {
BasicProcessImage processImage = new BasicProcessImage(slaveId);
processImage.setAllowInvalidAddress(true);
processImage.setInvalidAddressValue(Short.MIN_VALUE);
processImage.setExceptionStatus((byte) 151);
return processImage;
}
}
But when I try to insert this code in my java program I have problems with the threads.
I do:
Change the code of the listener test and create a new class.
In java I have a jframe with two buttons, start server, stop server.
In the jframe I create a new instance of my listener class.
In the start button I start using my class the listener.start().
The start button freezes, if I debug in the listener.start() the code stops.
Do you have some example with listener in jframe or similar?
Thanks in advance.
Best regards.
