Replacement of an IM 157-1 PN
If you replace an interface module with an interface module that has already been used, you
must reset this IO device to the delivery state with "Reset to factory settings".
You will find more information on "Resetting to factory settings" in the ET 200AL Distributed
I/O System ( http://support.automation.siemens.com/WW/view/en/89254965 ) system manual
in the section "Resetting interface module (PROFINET) to factory settings".

2.3.2 PROFIenergy
2.3.2.1 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.
