Adam Jensen - 2016-05-20

I'm writing an application that runs a Modbus slave. Within the application, I need to check the register address of requests, but they all evaluate to 0. I have tracked the issue to ModbusTCPTransport where createModbusRequest(int functionCode) is called, calling the parameterless constructor of the specific ModbusRequest class. setReference is never called on the request (anywhere that I can see).

I'm currently trying to acquire the reference in the following way:

int reference = ((WriteSingleRegisterRequst) this.request).getReference();

How do I properly get the reference of TCP requests?

  I just realized there was a maven repo and am going to try out v2.1
  
  Just in case, though, the above issue happened on v1.06

    And now I just realized v2.1 uses SLF4J, which isn't supported on the platform I'm planning to run my application on (Compact Profile). Can anyone help me with the above issue?

Sorry, nevermind. I created an MCVE and when the issue reproduced I checked the master. Turns out the master was configured incorrectly.
