8.1 Standby Management

8.1.1 EnergyStandbyManagementType

The EnergyStandbyManagementType ObjectTypes provide access to the Standby Management functionality of one Standby Management Entity. Parallel access of Clients to the read only data shall be possible but write operations and Method invocation can be limited to one Client at a time with the Lock Object.

The StandbyManagementStatus Variable shall contain the current state of the Standby Management. The value of this Variable shall be consistent with the content of the EnergySavingModeStatus Object.

The values of the 0:EnumStrings of the StandbyManagementStatus shall follow the definition of Table 13. Each instance shall have the values 0 to 8. Element numbers 9-15 are reserved for future use. If vendors add specific elements, the range 9-15 shall be filled with ‘null’-strings.

The Variables of the EnergyStandbyManagementType have additional Attributes defined in Table 14

The EnergySavingModes container Object contains References to EnergySavingModeType Objects representing the supported Energy Saving Modes.

Writing the PauseTime Variable can be used to update the pause time alternatively to the StartPause Method. Setting the PauseTime Variable with a value not equal to 0 shall have the same effect as invoking the StartPause Method passing the PauseTime value. Setting the PauseTime Variable with a value equal to 0 shall have the same effect as invoking the EndPause Method. An additional benefit is that the Variable PauseTime can be used in a PubSub communication scenario where the PauseTime is distributed by a central time management client using a broadcast telegram to which every Standby Management Entity subscribes.

The Lock Object ensures exclusive write access and Method call for one client. Write access and Method calls from Clients shall be blocked unless the client has locked the Object by invoking the InitLock Method of the Lock Object.

The StartPause Method starts the transition to an Energy Saving Mode. The SwitchToEnergySavingMode allows the transition into a specific Energy Saving Mode. The EndPause Method ends the Energy Saving Mode.

A RepresentedBy Reference may connect the Object to the representing PROFIenergy service access point Object (see PeServiceAccessPointType). The BrowseName of the Reference shall be “PESAP”.

8.1.1.1 StartPause Method

This Method starts the transition into an Energy Saving Mode.

Signature

	StartPause (
		[in]  0:Duration	PauseTime
		[out] 0:Byte		ModeID
		[out] 0:Duration	CurrentTimeToDestination
		[out] 0:Duration	RegularTimeToOperate
		[out] 0:Duration	TimeMinLengthOfStay
		[out] 0:Byte		ReturnCode
		);
	

The Method Result Codes (defined in Call Service) are defined in Table 15.

8.1.1.2 SwitchToEnergySavingMode Method

This Method initiates a switch to a certain Energy Saving Mode.

Signature

	SwitchToEnergySavingMode (
		[in]  0:Byte		ModeID
	[out] 0:Byte		EffectiveModeID
	[out] 0:Duration	CurrentTimeToDestination
		[out] 0:Duration	RegularTimeToOperate
		[out] 0:Duration	TimeMinLengthOfStay
		[out] 0:Byte		ReturnCode
		);
	

The Method Result Codes (defined in Call Service) are defined in Table 15.

8.1.1.3 EndPause Method

This Method ends the current Energy Saving Mode.

Signature

	EndPause (
		[out] 0:Duration	CurrentTimeToOperate
		[out] 0:Byte		ReturnCode
		);
	

The Method Result Codes (defined in Call Service) are defined in Table 15.

Table 15 shows the possible values for the Method call result codes.

Table 16 shows the possible values for the out parameter ReturnCode.

8.1.2 EnergySavingModesContainerType

8.1.3 EnergySavingModeStatusType

The CurrentTransitionData Variable contains details for the state transition indicated by the StateInformation Variable.

The StateInformation Variable contains details for the actual Energy Saving Mode state.

8.1.4 EnergySavingModeType

The EnergySavingModeType provides detailed information for a specific Energy Saving Mode.

The BrowseName shall contain a unique name for the Energy Saving Mode.

The ID Variable shall contain a unique mode ID for the Energy Saving Mode. The mode ID’s 0x00, 0xF0, 0xFE and 0xFF are reserved for predefined states.

DynamicData shall indicate whether the time, energy consumption and power values can vary (slightly) during runtime.

The TimeMinPause Variable shall contain the minimum pause time for this Energy Saving Mode.

The TimeToPause Variable shall contain the expected time to switch to this Energy Saving Mode.

The TimeMinLengthOfStay Variable shall contain the time of minimum stay in this Energy Saving Mode.

The TimeMaxLengthOfStay Variable shall contain the time of maximum stay in this Energy Saving Mode.

The RegularTimeToOperate Variable shall contain the time value to reach ”Ready to operate” (see Figure 1) if this Energy Saving Mode will be regularly terminated.

The ModePowerConsumption Variable shall contain the power consumption in this Energy Saving Mode. Unit: [kW].

The EnergyConsumptionToPause Variable shall contain the energy consumption from ”Ready to operate” to this Energy Saving Mode. Unit: [kWh].

The EnergyConsumptionToOperate Variable shall contain the energy consumption from this Energy Saving Mode to ”Ready to operate”. Unit: [kWh].
