Data Polling

The Data Polling tab configures how the device reads values from other BACnet devices on the network. Each row is a network input that can be fed by a COV subscription or by periodic reads. The list at the top shows every input with its current settings. Select a row to edit it in the Configuration panel below.

There are 20 network inputs:

• Network Digital Input 1 to Network Digital Input 16, each fed from a remote binary value and routed to a button or occupancy destination.
• Network Analog Value 1 to Network Analog Value 4, each fed from a remote analog value and routed to a light sensor or potentiometer destination.

Input list

Column	Description
Input	Name of the network input (Network Digital Input 1 to Network Digital Input 16, Network Analog Value 1 to Network Analog Value 4).
Mode	Acquisition mode for the input (Disable, Subscribe Confirmed COV, Subscribe Unconfirmed COV, or Polling / COV without subscription).
Device ID	Device identifier of the remote device.
Object Type	BACnet object type read on the remote device.
Instance	Instance number of the remote object.
Interval (s)	COV subscription lifetime, or the polling interval, in seconds.
Destination Type	Where the acquired value is routed (Button, Occupancy, Light Sensor (CO), or Potentiometer (LO)).
Destinations	Outputs driven by the value, listed as CO1 to CO5 or LO1 to LO5.

Configuration

Edit the selected input with the fields in the Configuration panel.

Field	Description
Mode	Acquisition mode for the input. Disable deactivates the input. Subscribe Confirmed COV and Subscribe Unconfirmed COV subscribe to change-of-value notifications from the remote object. Polling / COV without subscription reads the remote object at a fixed interval instead of subscribing.
Device Id	Device identifier of the remote device to read from.
Object Type	BACnet object type to read (Analog Input, Analog Output, Analog Value, Binary Input, Binary Output, Binary Value, Multi-state Input, Multi-state Output, or Multi-state Value).
Object Instance	Instance number of the remote object.
Life Time / Interval	COV subscription lifetime, in seconds, for the two Subscribe modes. For the Polling / COV without subscription mode the label changes to Interval and sets the read period, in seconds.

Destination

Digital Input

Shown for Network Digital Input 1 to Network Digital Input 16.

Field	Description
Destination Type	Where the digital input value is routed: Disabled, Button, or Occupancy.
Inverted	When checked, the incoming value is inverted before it is applied.
Destination Outputs	Five checkboxes, CO1 to CO5, selecting the control outputs the occupancy value drives. Shown only when the destination type is Occupancy.

Analog Value

Shown for Network Analog Value 1 to Network Analog Value 4.

Field	Description
Destination Type	Where the analog value is routed: Disabled, Light Sensor (CO), or Potentiometer (LO).
Destination Outputs	Five checkboxes selecting the outputs the value drives. Shown for any destination type other than Disabled. The checkboxes are labelled CO1 to CO5 for a Light Sensor (CO) destination and LO1 to LO5 for a Potentiometer (LO) destination.

Read and Write

Use Read to load the current data polling configuration from the device, and Write to send the edited configuration back to the device.
