BACnet MS/TP Subordinate Object Configuration – Analog Objects
Click the Set Up BACnet Names, Units, and COV button at the bottom of the BACnet MS/TP Subordinate
Configuration page to access the Object Configuration page.
When in Auto-Configure Mode, these fields are not configurable. You MUST be in Manual Configure
Mode.
Follow these steps to customize analog inputs or outputs in Manual Configure Mode:
1) Select Analog Input or Analog Output from the upper left dropdown menu.
2) Select a Group to use.
a) These group names are defined on this page under the "Group Name" dropdown menu.
b) Use case example: If there are multiple server/Subordinate devices the RTA gateway is
monitoring and sending over to the Build Automation System (BAS) to monitor, you can
configure the group to represent each device. The image above displays 1 device, if there are 5
total devices then you can call Group 1 "Basement", Group 2 "1
etc..
3) Enter a Name to identify this object on the network.
4) The combination of Group and Name should be unique for each point in the gateway.
5) Select the Unit Category corresponding to the units you want this object to be identified with
(optional). Then select the Unit from the dropdown menu.
6) Set the COV (Change of Value) for this object.
7) If the BACnet MS/TP Manager issues a COV-Subscription, the gateway will issue a COV Notification
when the Present-Value changes by more than the given COV-Value. This value shift can be in a
positive or negative direction.
