IntroductionThis guide describes the BACnet IP interface for the PowerHawk 4000 and 6000 series of power meters. This interface has been designed to comply with the ANSI/ ASHRAE Standard 135.1-2009. It can be used with any BTL- compliant BACnet IP applications to read meter measurement data as part of an integrated building energy management system.

This interface is fully BTL-tested and BTL-compliant. Refer to “Appendix A: Product Implementation Conformance Statement” on page 9 for the Product Implementation Conformance Statement for the PowerHawk 4000 and 6000 series meters.

This guide provides information about configuring the BACnet interface, and describes the BACnet objects and services supported by the PowerHawk meters and the specific meter data that can be read from each meter, as follows:

• “PowerHawk meter BACnet configuration” on page 1• “PowerHawk 4000 and 6000 series meters BACnet objects” on page 3• “BACnet device object” on page 3• “Analog input objects” on page 5• “Accumulator objects” on page 7• “Proprietary object properties” on page 7• “Appendix A: Product Implementation Conformance Statement” on page 9

PowerHawk meter BACnet configurationThe BACnet IP interface for the PowerHawk 4000 and 6000 series meters is configured using the Triacta Configuration Tool; refer to the PowerHawk Multi-Circuit Meters Configuration Guide for information and instructions on using the tool to configure the meters.

Figure 1 shows the BACnet configuration tab in the Configuration Tool and Table 1 provides a programming description of each field.

PowerHawk 4000 and 6000 series meters BACnet objectsOnce the PowerHawk meter BACnet/IP interface is properly configured, the following BACnet objects will be accessible from any BTL-compliant BACnet/IP application, and will be discovered by most BACnet Discovery tools:

• Device object• Analog input objects• Accumulator objects• Proprietary object properties

These objects provide device-specific information as described in the following sections.

BACnet device object

TheBACnet device object provides information regarding the standard BACnet objects and services that the PowerHawk meter supports, as well as device-specific information such as vendor name, model name, and firmware version. This information is also listed in “Appendix A: Product Implementation Conformance Statement” on page 9.

Model nameThe model name is important to note because it describes the number of circuits and phase elements configured for the meter being read. This, in turn, is reflected by the number of Per Meter Circuit and Per Element analog input objects supported for each meter.

The model number and configuration of the meter is reported in the form:

mmmm-vvvv-cc-cc

where:

mmmm is the model numbervvvv is the voltagecc-cc is the circuit configuration

Example: 4324-120V-3P-08

Table 2 lists the supported PowerHawk meter models and configurations. The configuration determines the number of circuits and the number of elements in each circuit that are reported by the meter.



Table 2: Supported meters and configurations

Note: 1. PowerHawk meters 4106 and 4124 use 100mA output CTs.2. PowerHawk meters 4206 and 4224 use 333mV output CTs.3. PowerHawk meters 4306, 4324, 6303 and 6312 use 80mA output CTs.4. PowerHawk meter 6412 uses 5A output CTs.

Protocol object typesThe following three protocol object types are supported by the PowerHawk 4000 and 6000 series meters:

• Device• Analog input• Accumulator

SegmentationBACnet packet segmentation is NOT supported by the PowerHawk 4000 and 6000 series meters.

Triacta recommends using the ReadProperty service to read single objects. If you use the ReadPropertyMultiple service, you must limit the list of objects to be read and do not use reading-all with this service.

Analog input objects

The following analog input objects identify the PowerHawk meter data that is returned in the present value property when reading the specified analog input object.

Except where indicated, all analog input objects are updated every 5 seconds.

Per meter circuit (Meter x)The following analog input objects are reported for each meter circuit (Meter x).

The number of discovered meter circuits is determined by the model number and configuration of the PowerHawk meter. For example, if the meter configuration is 3P-02, there are two meter circuits. Refer to Table 2 for the number of circuits for each PowerHawk model number and configuration.

NOTE: Peak/ Present Demand must be enabled in the Types tab of the Report section in the PowerHawk configuration tool to enable demand data. The demand calculation type (Block or Sliding Window Demand) and the demand interval duration are specified during meter configuration. Refer to the PowerHawk Multi-Circuit Meters Configuration Guide for details on how to configure the parameters in the Report section of the configuration tool.

Object name Description Units

Meter x Active Power Current active (real) power Watts

Meter x Reactive Power Current reactive power VARs - Volt Ampere Reactive

Meter x Apparent Power Current apparent power VAs -Volt Ampere

Meter x Power Factor Current power factor pf

Meter x Peak Demand Highest demand measured over any demand time interval since either the meter was commissioned or since the last Peak Demand Reset.

Watts

Watts



Per meter circuit and meter element (Meter x, Element p)The following analog input objects are reported for each meter element (p) on each meter circuit (x).

The number of discovered elements per meter circuit for each PowerHawk meter is determined by the model number and configuration. For example, if the meter configuration is 1P-12, there are two elements per meter circuit. Refer to Table 2 for the number of circuits and elements for each PowerHawk model number and configuration.

Pulse input countersThe analog input object pulse inputs are used for test purposes only. They show the time interval pulse count from the end of the previous non-zero time interval. Data is updated at the end of the meter time interval only if there was a pulse count in that time interval.

NOTE: The Pulses report type must be must be enabled in the Types tab of the Report section in the PowerHawk configuration tool to enable the pulse count registers. Refer to the PowerHawk Multi-Circuit Meters Configuration Guide for details on how to enable the pulse count and set the pulse scale factor parameters in the configuration tool.

Accumulator objects

The following accumulator objects identify the PowerHawk meter data that is returned in the present value property when reading the specified accumulator object.

These objects report the total measured units from when the meter was commissioned, or from when the register last overflowed, to present.

All accumulator objects are updated every 5 seconds.

NOTE: The Pulses report type must be must be enabled in the Types tab of the Report section in the PowerHawk configuration tool to enable the pulse count registers. Refer to the PowerHawk Multi-Circuit Meters Configuration Guide for details on how to enable the pulse count and set the pulse scale factor parameters in the configuration tool.

Proprietary object properties

The following proprietary object properties are supported by the PowerHawk 4000 and 6000 series meters. Proprietary object properties may not be shown in the objects list generated by some BACnet discovery services.

When performing a ReadProperty of a Meter x Peak Demand analog input object, the proprietary Property ID 1500 will contain the Peak Demand timestamp.

1500 Analog-Input Unsigned INT Unix timestamp

Returns the timestamp of the Peak Demand interval.

Peak Demand Reset

1501 Device Character String Write any value to this property to reset the Peak Demand value for all applicable objects.



The Peak Demand timestamp identifies the end of the Demand time interval during which the current Peak Demand value was recorded. The timestamp is in UTC and is represented by a 32-bit unsigned integer in Unix format (YYYY/MM/DD,HH:mm).

The Peak Demand value is reset on all circuits (meters) by performing a WriteProperty to the Device Object with proprietary Property ID 1501 set to any value.
