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.

Table 41 – EnergyStateInformationDataType Structure

Name Type Description
EnergyStateInformationDataType Structure  
   IDSource 0:Byte Mode ID of current Energy Saving Mode.
   IDDestination 0:Byte Mode ID of destination Energy Saving Mode.
   RegularTimeToOperate 0:Duration Time needed to reach „Ready to operate“ if the Energy Saving Mode is regularly terminated. Shall be 0 if IDSource is equal to 0xFF (The StandbyManagementStatus Variable has the value “Ready to operate”).
   ModePowerConsumption 0:Float Power consumption in actual state.

Its representation in the AddressSpace is defined in Table 42

Subtype of the Structure type defined in [OPC 10000-3]

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.
