Assigning RTU Parameters
The RTU Screen is accessed by clicking on any of the RTU Icons on the Home screen. It is used to enter
all the parameters of the selected RTU.
RTU Description – Enter a description of the RTU. Generally the description identifies the location of
the RTU.
Note: The drop down box allows the user to jump to other RTUs without retuning to the Home Screen.
Fault Output – This selection allows the RTU to activate one or more of its outputs if data
communication is lost with the system control computer. Typically this feature would be used to signal
the major fault condition to personnel located in the RTU’s service area since the RTU is essentially
inoperative without data connectivity to the control computer. To implement this, a “Data
Communication” fault event should be created on the Event List screen; then, assigned to one or more
outputs on the RTU Output screen.
Enable Polling – The Enable Polling checkbox is used to activate the RTU so it is recognized by the
control computer. This feature is typically used during system commissioning to bring the RTUs on line
one at a time as they are installed. Select the checkbox to enable the RTU.
AMI Present: The AMI Present checkbox is used to activate data communication between the RTU and
an Audio Messenger Interface (AMI). Select the checkbox if an AMI is connected to the RTU.
