Embedded programmable java instance

[Jørgen Bundgaard Wanscher]

I am working on a project where we are producing specialized hardware controlled by a java application through the modbus protocol.

For automated testing purposes (only software without the actual hardware) we would like to instantiate a properly configured slave instance from the test code. I can see that I have to use the ModbuspalPane class, but it is unclear how to go from there to set up coils and registers when I have created a ModbusPal.slave instance.

Best regards

Seems like I figured most of it out by skimming the source code - hurray for OSS :-)

1. Instantiate a slave (ModbusPal.slave.ModbusSlave)
   slave = new ModbusSlave(0);
2. Setup Coils and Holding registers through getCoils and getHoldingRegisters methods on the slave instance.
   slave.getCoils().create(....)
   slave.getHoldingRegisters.create(....)
3. Create a project (ModbusPalProject)
   ModbusPalProject project = new ModbusPalProject();
4. Use the submitModbusSlave method on the project instance to attach the configured slave
   project.submitModbusSlave(slave);
5. Make the pane instance and use the newly created project
   modbuspal = ModbusPalGui.getInstance(instanceKey);
   modbuspal.setProject(project);
6. Now use the start and stop commands on the pane to control operation of the slave

Open issues:
a) How do I programmatically change the port number of the slave/project
b) How do I programmatically change the name of the project
- note that both open issues could be solved by saving to XML and then modifying the XML and reloading, or by modifying the modbuspal source code but I hope there is an easier way to achieve a) and b) :-)
