The Mock driver is usefull for developing applications without available hardware. Reads from Mock devices work, but writes seem broken. Scenario: implement *MockDevice* interface and the *write* method. See that this device is set in the connection using the *MockConnection*.*setDevice* method. When a WriteRequest is issued on the connection, the *MockDevice*.*write* method is indeed called, but the *value* parameter is always _*null*_. The given value to write is not passed through. Debugging and looking into the sourcecode shows following: *MockConnection.write* uses following statement to retrieve the value: ``` // MockConnection:147 ((MockField) writeRequest.getField(name)).getPlcValue() ``` This retrieves the *plcValue* member from the MockField object. This *plcValue* is written to by constructor *MockField(String address, MockPlcValue plcValue)* only. However, I did not find any call to this constructor. Note: Other Drivers seem to use ``` writeRequest.getPlcValue(fieldName) ``` instead and do not have a value member in the Field class.
