Functions and Setup of the Network Room Module
The NRM is a network device with no hardware inputs or outputs and
connects to the Facility Explorer controller via the display (or local link)
bus. All the communication access and setup of the NRM is done through
the controller where the NRM is connected. The configuration properties
of the NRM are set in the Room Sensor object in the controller when the
control application for the controller is generated in the FX Builder tool.
When the application is downloaded to the controller, you use the
FX CommPro N2, LON, or BACnet commissioning tool to monitor the
network variables of the NRM in the Room Sensor object through the
network profile of the controller.
This section describes the various functions and display features of the
NRM, the network variables used by each function, and the configuration
properties used to set up each function.
