4.10 PROFIenergy Profile
The Anybus CompactCom 40 PROFINET IRT supports the PROFIenergy profile, according to
the PROFIenergy Technical Specification, rev. 1.2. This profile makes it possible for a user to
temporarily put a device in energy saving mode, e.g. during a lunch break or during weekends.
The amount of power used by machines, when they are not in active use is thus reduced. Each
device can be set individually to the energy saving mode that is the most optimal depending on
the length of the production stop. Operators in factories, for example, can easily set all devices
at the same time, in the, for each device, optimal energy saving mode.
The application defines the time for how long the device will stay in energy saving mode, and
the device decides which mode will be the most appropriate. Transitions between the “Ready to
operate” mode and all saving modes are mandatory, while transitions between different energy
saving modes are optional. The transition from “Ready to operate mode” to “Power off mode” is
not mandatory, as repowering the device may mean hands on restart.
4.10.1 Implementation
The PROFIenergy profile is implemented in the Anybus CompactCom 40 PROFINET IRTac-
cording to the state machine described in the PROFIenergy Technical Specification (available
from PROFIBUS International). PROFIenergy commands arriving from the network will be
translated into the Anybus CompactCom implementation as follows:
PROFIenergy command Anybus CompactCom 40 implementation
Start_Pause Translated into a StartPause command to instance #0 in
the Energy Control Object.
Start_Pause_with_time_response Same as Start_Pause but will do several reads of the En-
ergy Control object, and the currently used energy saving
mode to complement the response.
End_Pause Translated into a EndPause command to instance #0 in
the Energy Control Object.
List_Energy_Saving_Modes Instances present in the Energy object will be listed.
Get_Mode Supported attributes for the requested mode/instance will
be read.
PEM_Status Results in several reads of Energy Control object and the
currently used energy saving mode.
PEM_Status_with_Ext1
PE_Identify Returns a static list of the supported, and also mandatory,
PROFIenergy commands.
Get_Measurement_List Returns the list of supported measurement values from
the Energy Measurement object.
Get_Measurement_Values Returns the actual measurement values from the Energy
Measurement object.
Get_measurement_List_with_object_number Returns the list of supported measurement values from
the Energy Measurement object.
Get_Measurement_Values_with_object_number Returns the actual measurement values from the Energy
Measurement object.
Query_Version Return the supported PROFIenergy version.
Info_Sleep_Mode_WOL Not supported.
Go_Sleep_Mode_WOL
The PROFIenergy profile is valid for all sub-slots and is accessed through index 80A0h. Maxi-
mum number of instances/modes in the Energy Control Object is 8.
