Network Room Module Parameters (Room Sensor Object)
Table 5, Table 6, and Table 7 list the network variables and configuration
properties available in the NRM Room Sensor object. You must create an
instance of this object in the FX controller for the connected NRM. The
controller automatically transfers the configuration data to the NRM
module and transmits and receives the network variable information over
the local link bus.
Note:
The configuration properties are also available as network
variable inputs so that they can be dynamically changed in the application
in the controller at runtime.
