new to ignition and hmi software. Would like to setup a network to communicate with an I/O Flex 6126 controller to monitor the HVAC equipment parameters.  
I currently have a RS485 network up and running to another device via ignition and windows PC.  
The HVAC I/O Flex 6126 controller has a communicating thermostat connected to the Rnet connection and a inverter drive connected to port 2a configured for BT485 modbus.  
What network do I connect to, to view the variables of the controller (temperatures, component status, air flow, invertor speeds, etc) and how?
