This object contains attributes common to many Metasys system objects. These common attributes are described in the Common Object Attributes section. This section includes attributes of the Focus/Configuration tab, the Diagnostics tab (if applicable), and any other tab specific only to this object. See the Object and Feature Tabs section for information on the attributes that appear on the other tabs of this object (for example, the Hardware and Options tab appear on point objects).

Note: In the Notes column, letters indicate the following: In the notes column, letters indicate the following: C - Configurable, D - Default Attribute for Display, N - Value Not Required, R - Affected by Extension’s Reliability, W - Writable.

Attribute Name

Notes

Initial Value

Values/Options/Range

Attribute Description

Calculation

 

0

0–4,294,967,295

Increases by one each time the Pulse Meter object executes its main routine until it rolls over and starts again with zero.

Consump Unreliable

W

False

 

Indicates that the Consumption attribute may contain unreliable data. The following conditions can set the Consump Unreliable attribute to True:

– If the calculated rate is too high, which happens if the Rate Limit is exceeded.

– If the Pulse Meter object is disabled.

– If the value of the Accumulator object is unreliable.

Consumption

W

0

Units = Consumption Units

Indicates the consumption since the last reset of the Pulse Meter object.

Consumption Units

C,W

kWh

Uses Unit Set (Set 869).

Indicates the measurement units for all consumption attributes.

Counter Object

C,W

   

Specifies the associated Accumulator Object or Counter Input Object (defined by CCT).

Display Precision

C,W

10ths

 

Specifies the rounded position and decimal places to display for this object’s analog values.

Execution Trigger

W

False

 

When written to True, the execution function runs.

Meter Active

C,W

True

True, False

Specifies whether the pulse meter object currently should be metering.

Present Value

D,R

 

Units = Rate Units

Represents the currently calculated rate of consumption.

Previous Consumption

W

0

Units = Consumption Units

Indicates the last value of Consumption before the last reset.

Pulse Consumption

C,W

1.000000

Units = Consumption Units

Specifies the physical quantity that each single pulse represents.

Pulse Count

   

0–4,294,967,295

Indicates the pulse counter value as last reported from the Counter Input Object (define by CCT), or the last Present Value of the Accumulator Object.

Rate Constant

C,W

3600.000000

 

Specifies the value multiplied by the Consumption Units to get the Present Value units to match Rate Units.

Rate Default

C,W

0.0

> = 0, Units = Rate Units

Specifies the value of Present Value when the calculated rate exceeds the Rate Limit.

Rate Limit

C,W

3.402823466

E38

> = 0, Units = Rate Units

Specifies the highest allowed Present Value before using Rate Default.

Rate Units

C,W

kW

Uses Unit Set (Set 869).

Indicates the measurement units for all rate attributes.

Rate Unreliable

 

False

 

Indicates that the Present Value is unreliable because of a misreading of a counter.

Reliability

 

Reliable

Uses Reliability (Set 503).

Indicates if a value is questionable.

Reset

W

False

True while reset in progress

When written to True, it transfers the current value of the Consumption attribute into the Previous Consumption attribute before resetting Consumption to zero.

Reset Date

W

   

Indicates the date of the last resetting of Consumption attribute.

Reset Time

W

   

Indicates the time of the last resetting of Consumption attribute.

Rollover Limit

C,W

32767

0–4,294,967,295

Specifies the highest counter value before the pulse counter rolls over to zero. This value must match that of the counter, or the Max Value of the Accumulator.

Sample Time

C,W

60

Units = seconds, Value > 9

Specifies the period of automatic executions of the algorithm in seconds.
