Enabling PROFIenergy for transfer areas of I-devices
Proceed as follows to assign parameters for the support of PROFIenergy:
1. Select the PROFINET interface (X1) of the CPU.
2. Select the required transfer area in the area navigation, for example:
Operating mode > I-device communication > Transfer_area_1.
3. Select the check box "Enable PROFIenergy communication".
Figure 5-20 Configuring PROFIenergy with I-devices
Once the I-device is fully configured, generate the GSD file for the I-device and import this
file in the project for the I/O controller. The GSD file generated contains an entry that
specifies that the I-device supports the PROFIenergy profile.
To address the I-device, for example for the PE command "PE_START_END", use the
hardware identifier of the "PROFIenergy supporting" transfer area in the I-device.
To address the IO controller for the PE command "PE_I_DEV", use the hardware identifier of
the transfer area that is supplied with the data for PROFIenergy on the IO controller.
You can find more information on PROFIenergy in the sectoin Saving energy with
PROFIenergy (Page 243).
