PROFIenergy

7.1

Pause function

Introduction
PROFIenergy is a PROFINET-based data interface for switching off consumers centrally and in
a coordinated manner during pause times regardless of the manufacturer or device type. This
has the aim that the process is only provided with the energy that is absolutely required. In so
doing, the majority of the energy savings come from the process itself; the PROFINET device
contributes only a few watts to the possible savings. In PROFIenergy, this operating state is
referred to as a "pause".
Start and end of a pause
You enable and disable the pause function of the system at the beginning and end of pauses,
respectively; the IO controller then sends the PROFIenergy command "Start_Pause" or
"End_Pause" to the modules.
Use the "Start_Pause" command to start a pause.
Use the "End_Pause" command to end a pause.
The following conditions will also cause a pause to be ended:
• Reconfiguration in RUN
• Controller failure
• Firmware update
• Station stop
• Restart of the interface module through:
– POWER OFF/POWER ON of an interface module
– POWER OFF/POWER ON of an I/O module
– Termination of ET-Connection1 or ET-Connection2
The specific behavior of the digital output module is explained in the following sections.
