Allowed-Signal-Types

SigTypSprtd

Supported signal types

A read-only proprietary property that specifies a selectable set of sensor types for the input. Input/sensor types are provided for temperature, resistance, current, and voltage. Supported signal types: I420, U10, NI1K, PT1K375, PT1K385, NTC10K, NTC100K

Signal-Type

Signal-Type

SigTyp

The subset of supported signal types is HW specific and depends on the Allowed-Signal-Types property.

Present-Value-1

PrcVal1

Process value 1

Defines the first physical value in engineering units of the conversion characteristic to calculate the present value out of the measured sensor value.

Signal-Value-1

SigVal1

Signal value 1

Defines the first signal value of the conversion characteristic to calculate the present value out of the measured sensor value.

Present-Value-2

PrcVal2

Process value 2

Defines the second physical value in engineering units of the conversion characteristic to calculate the present value out of the measured sensor value.

Signal-Value-2

PrcVal2

Signal value 2

Defines the second signal value of the conversion characteristic to calculate the present value out of the measured sensor value.

COV-Signal-Limit

RawValCOV

COV increment signal value

Throttle
The data acquisition COV triggers an update to the present-value of the Input object. The Input object then decides whether the value change requires a BACnet COV notification based on the object's cov-increment property.

COV-Repetition-Timer

TiExcgRptCl

COV repetition time

Heartbeat
A writable proprietary enumerated property that configures the time interval between data acquisition COVs to the Input object. Data acquisition COVs will be sent at this interval even if the raw sensor value does not change by COV-Signal-Limit. COV-Repetition-Timer is not used for onboard I/O and is ignored.
