I've created a modbus IP data source and data point.
I'm also running this server in localhost:502 http://code.google.com/p/modbus-tk/source/browse/trunk/examples/tcpslave_example.py
If I use th scan nodes feature, Mango successfully finds the single slave in the server. But if I create a Data point for the slave 1 no data is recorded in Mango and no output appears in the server stdout.
Am I missing something? This is supposed to work.
