StandbyModeTransitionDataType

Structure

IDDestination

0:Byte

Mode ID of destination Energy Saving Mode.

CurrentTimeToDestination

0:Duration

Time needed to reach the mode IDDestination. Shall be a “Worst case” value if ongoing (dynamic) time value is not supported. Shall be 0 if destination Energy Saving Mode is reached.

CurrentTimeToOperate

0:Duration

Time needed to reach “Ready to operate” if the Energy Saving Mode is not regularly terminated. The server might update the value after reaching the destination state as long as the TimeMinLengthOfStay of the destination state is not reached.

EnergyConsumptionToDestination

0:Float

Energy consumption for actual transition. Shall be 0 if not in a transition state.

Figure 16 shows how CurrentTimeToOperate varies in dependence of TimeToPause and TimeMinLengthOfStay of the destination Energy Saving Mode during and immediately after the transition.

The relationship of RegularTimeToOperate and CurrentTimeToOperate during a mode transition shall follow Figure 16. A more comprehensive explanation may be found in PE 3802.

The EnergyStateInformationDataType holds information specific to a certain state which also does not change if the device is in transition state. The members shall have the values characterizing the current state and shall be changed only in case of a transition to a different state.

If the StandbyManagementStatus Variable of the EnergyStandbyManagementType Object has the value 2 (“Ready to operate”), IDSource and IDDestination shall be equal and have the value 0xFF.

If this StandbyManagementStatus Variable has the value 0 (“Energy saving disabled”), IDSource and IDDestination shall be equal and have the value 0xF0.

If this StandbyManagementStatus Variable has the value 4 (“Energy saving mode”), IDSource and IDDestination shall be equal and have the value of the ID Property of the EnergySavingModeType Object representing the current Energy Saving Mode.

If this StandbyManagementStatus Variable has the value 3 (“Moving to energy saving mode”) and if the previous value was 2 (“Ready to operate”), IDSource shall have the value 0xFF and IDDestination shall have the value of the ID Property of the EnergySavingModeType Object representing the destination Energy Saving Mode.

If this StandbyManagementStatus Variable has the value 3 (“Moving to energy saving mode”) and if the previous value was 4 (“Energy saving mode”, the state transition takes place between two Energy Saving Modes), IDSource shall be the value of the ID Property of the EnergySavingModeType Object representing the source Energy Saving Mode. IDDestination shall have the value of the ID Property of the EnergySavingModeType Object representing the destination Energy Saving Mode.

If this StandbyManagementStatus Variable has the value 5 (“Moving to ready to operate”), IDDestination shall have the value 0xFF. IDSource shall have the value of the ID Property of the EnergySavingModeType Object representing the source Energy Saving Mode.

This enumeration MeasurementPeriodEnum defines how a measurement period is to be interpreted. The enumeration is defined in Table 49.

Table 49 – MeasurementPeriodEnum Items

Name

Value

Description

SlidingDemand

0

The measurement period is interpreted to consider the last measurement period.

FixedBlockCompleted

1

The measurement period is interpreted to take the last completed measurement period aligned to the full hour.

FixedBlockInstantaneous

2

The measurement period is interpreted to take the current measurement period aligned to the full hour. That means, if for example only have of the measurement period has passed, only that half is considered.

FixedBlockPredicted

3

The measurement period is interpreted to take the current measurement period aligned to the full hour and predicts the duration that has not been passed. That means, if for example only have of the measurement period has passed, the first half of the considered values is based on real measurements while the second half takes predicted values.
