What is PROFlenergy?
Introduction
PROFIenergy is a PROFINET-based data interface which makes it possible to switch off
consumers in a coordinated and centrally controlled manner during break times regardless of
the manufacturer or device. 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".
PROFINET devices are switched off with special commands in the user program of the
PROFINET IO controller. Additional hardware is not needed: The PROFIenergy commands
are interpreted by the PROFINET devices.
The device which provides PROFIenergy and supports the matching control data record
owns the PE-Entity, the access point for these control data records. This PE-Entity
represents I/O modules which do not have their own PE-Entity on the interface module.
I/O modules that have their own PE-Entity are always addressed directly.
For the ET 200AL distributed I/O system, the PE-Entity is exclusively provided by the
PROFINET interface module.
To configure PROFIenergy, follow these steps:
1. Create the parameter data record, Index 3, in STEP 7.
2. Transfer the parameter data record to the interface module with the instruction
"WRREC" - SFB 53.
3. Create the user program with the FBs to control the PROFIenergy commands
("PE_START_END" - FB 815, "PE_CMD" - FB 816).
4. Transfer the user program to the CPU.
