The duration description for the activation delay duration temporal entity

The duration description for the active duration (min and max, sum max and sum min) temporal entities

The active maximum duration a power sequence can run without interruption.

The active mininum duration a power sequence can run without interruption.

The active maximum duration a power sequence can run in total (summation of all active times).

The active minimum duration a power sequence must run in total (summation of all active times).

Independent from the ActuatorSwitch class, the ActuatorLevel class enables a user or application to model LEVEL commands (start, up, percentageAbsolute, relative, etc.). This can be used to dim a light, set the speed of an electric motor, etc.

Basic on/off operations on a simple actuator can be modelled with the ActuatorSwitch class. Whether the function turns a device itself ON or OFF, or whether it switches a specific feature, depends on the implementation. For example, one could model the super freeze program of a freezer using ActuatorSwitch class. An ON command would then activate the super freeze program and an OFF command would deactivate it. This example shall just give an idea how ActuatorSwitch can be used for more purposes than only turning devices on and off.

An Instruction as specified for an Demand Driven Based Control Profile.

A data point is a quantity that is extended with various pieces of process information, namely



- A creation time (instant). This is the point in time when the data point was created, which is not necessarily the time for which it is valid. In the case of soft-sensors or forecasters, a data point might have been created ahead of time, in the case of a direcet measurement a data point might created at its time of validity (or at the end of its validity time interval) and in the case of an archived value the data point might have been created after the fact.



- A validity time (temporal entity) which will be named "time stamp". The validity time is the instant or interval in time in which a specific quantity is in effect. For example a room temperature might be measured at 12:00, which means it is in effect at this very instant. A specific amount of energy might me expended within the time-slot between 12:30 and 12:45, which means that the energy measurement is in effect during this time interval.



- A location or topological association. For example, a measurement might be taken in a specific room, a power avarage might have been measured by a specific meter, a forecast might be valid for a specific region or grid segment. This association is therefore not always a location.

Most of the existing devices can expose at most 1 power profile, but there are special cases in which more than one power profiles can be exposed by the same device. For example, consider the case of a combined fridge-freezer in which there are 2 logical devices (fridge and freezer) combined in 1 physical device. This combined device can expose 2 power profiles, one for the fridge and one for the freezer. A s4ee:Device (e.g. a household appliance or a smart meter) can also receive events about overload warning severity level and related load control commands (LoadControlEventData)

Control Types dictates flexibility instructions. Control Type provides Flexibility options.

A data point whose quantity is a standard deviation.

An Incentive indicates the intersection of a tier with a slot. In this particular combination of slot and tier there are a particular costs to draw this type of energy.

The relationship between the power limit and its duration. Power limit may come with a time period of validity based on duration

Used to define a quantile for example on a data point of a quantile time series. The quantile must be a ratio, usually a percentage. In a quantile forecast the hasQuantile property cannot be empty

Adds a standard deviation to a data point.

The startTime of a power sequence or slot. SHALL be present

The resolution is the distance between two measurement time-stapms. This only makes sense if the measurements are equidistant.

Absolute costs for going through this Transition in the currency as described in the ResourceManagerDetails.

Indicates the time between the initiation of this Transition, and the time at which the device behaves according to the Operation Mode which is defined in the appropriate data element. When no value is provided it is assumed the transition duration is negligible.

Time at which the transition from the previous Operation Mode was initiated. This value shall always be provided, unless the active OperationMode is the first OperationMode the Resource Manager is aware of.

The rate at which a data point or time-series or forecast or other data entity is being updated.



If the time series gets regularly updated, then the time between two updates can be recorded here.

The upper average power of an Energy constraint of a Power Envelope profile.

Power value expressed in the unit associated with the CommodityQuantity of the Power Value.

Indicates whether the power limit is currently active

A relationship indicating that this element can be changed by its operator. The boolean value indicates whether it is indeed changeable.



In the SAREF4ENER extension this property is intended for PowerLimits and IncentiveTable elements, such as the IncentivebasedProfile, IncentiveTableSlot, and the IncentiveTableTier.

Indicates when the Timer will be finished. If the DateTimeStamp is in the future, the timer is not yet finished. If the DateTimeStamp is in the past, the timer is finished. When the timer was never started, the value can be an arbitrary DateTimeStamp in the past.

This property indicates whether the PowerSequence is interruptible.

A relationship between the power limit and the boolean value indicating whether the power limit is obligatory

Specifies if the power sequence is pausable.

Specifies if the power sequence is stoppable.

A description for the device as defined by the manufacturer.

A short label of the device as defined by the manufacturer.

Indicates a node identification for the device as defined by the manufacturer. This could be used for the identification of a device, even if it was removed from the network and rejoined later with changed node address.

States the maximum amount of starts a power sequence (of a device) allows per day.

Enables the identification of different sensors on one EEBus address.

An identifier for one specific message. If a message is marked as obsolete, this number can be used to identify the original message.

Indicates the type of the message. Possible values are:

- logging (used for messages, that shall be stored in a log file)

- information (messages, that shall be presented to the customer on a display; lower priority)

- warning (messages, that shall be presented to the customer on a display; medium priority)

- alarm (messages, that shall be presented to the customer on a display; high priority; if there is an alarm device in the household, it shall generate an alarm)

- emergency (messages, that shall be presented to the customer on a display; very high priority; if there is an alarm device in the household, it shall generate an alarm; additionally, if possible and configured, an emergency call shall be done)

- obsolete (previously sent messages, that shall be marked as obsolete)

Indicates whether the power profile of a device is configured for remote control (e.g., by an energy management system).This refers to the selection chosen by the user on the remote control feature of the device. If nodeRemoteControllable is equal to FALSE, all the supported power sequences shall set the sequenceRemoteControllable property to FALSE. If nodeRemoteControllable is equal to TRUE, at least one power sequence shall be remotely controllable by setting the sequenceRemoteControllable property to TRUE.

Indicates whether a slot is optional (if set to TRUE). Otherwise, if a slot is mandatory, SHALL be omitted or set to FALSE. Note: This element applies to every repetition of the slot number.

Time that has passed since the selected sequence has started. A value must be provided, unless no sequence has been selected or the selected sequence hasn't started yet.

Contains the total number of repetitions, if a power sequence repeats its sequence of slots. Absence of the element is equal to a presence with a value of 0 (zero). SHALL be absent if the value is 1.

The relationship between the incentive table element and the boolean data indicating whether the incentive table requires an update.



In the SAREF4ENER extension this property is intended for the following classes:

- IncentiveTableBasedProfile

- IncentiveTableTier

- IncentiveTableSlot

Provides a unique power sequence identifier for a certain device

Denotes whether a power sequence is modifiable (if value is TRUE) or not (if value is FALSE). Modifiability is required to configure power sequences and slots. It is also required to change a power sequence state.

Indicates the serial number of a device as defined by the manufacturer. Usually the same as printed on the case.

If a slot is optional, represents the current status of the slot (true = the slot will be executed, false = the slot will not be executed). If the slot is not optional, this element SHALL be absent.

Provides a unique slot identifier for a certain power sequence

Indicates the software revision of a device as defined by the manufacturer.

If set toTRUE, the power profile of a device does not restrict the number of power sequence re-selections by the CEM, i.e. within a given alternative the CEM may first choose one power sequence, alter the selection by configuring another sequence later on, then alter the selection again, etc. (provided the process rules and data still permit configuration). If supportsReselection is set to FALSE, the device permits the CEM to select a power sequence of an alternative only once.

If set toTRUE, the power profile of a device does NOT permit the modification of more than one slot per configuration command.

Represents the task identifier of the power sequence.

Represents the total number of power sequences supported by the power profile of a device

Provides a code for the vendor of the device as defined by the manufacturer.
