SCALE

Integer/Float/String

Indicates the conversion factor to be multiplied with the value of the Present Value property to provide a value in the units indicated by Units.

For example:3.14

UNITS

String

0

PRESCALE

List of integers separated by semicolons (;) and encoded as a string

Presents the coefficients that are used for converting the pulse signals generated by the measuring instrument into the value displayed by Present Value

For example:-3413;-1119

MAX-PRES-VALUE

Integer

0

VALUE-CHANGE-TIME

Timestamp encoded as a string

This read-only property, of type BACnetDateTime, shall be present if the Present_Value property is adjustable by writing to the Value Before Change or Value Set properties

For example: 25-10-201315:39:23.27

VALUE-BEFORE-CHANGE

Integer

This property, of type Unsigned, indicates the value of the Present_Value property just prior to the most recent write to the Value Set or Value Before Change properties.

For example:100

VALUE-SET

Integer

This property, of type Unsigned, indicates the value of the Present_Value property after the most recent write to the Value Set or Value Before Change properties.

For example:786

PULSE-RATE

Integer

This property, of type Unsigned, shall indicate the number of input pulses received during the most recent period specified by Limit Monitoring Interval

For example:0

HIGH-LIMIT

Integer

0

LIMIT-MONITORING-INTERVAL

Integer

This property, of type Unsigned, specifies the monitoring period in seconds for determining the value of Pulse Rate

For example:500
