PROFIsafe configurations
TwinCAT IPC with PROFIBUS/PROFINET-EtherCAT Terminal
Without the use of the EL9930, the transmission of the PROFIsafe data from the EL6910 to the TwinCAT PC
would take place in the following example via the E-bus and EtherCAT. The TwinCAT PC would copy the
data in the process image and then send them with the next I/O update via EtherCAT and E-bus to the
PROFIBUS/PROFINET master.
By using the EL9930 between the EK1100 and the EL6920, the PROFIsafe telegram is secured in the
EL9930 and set to 0 in the telegram. In the data direction to the PROFIBUS/PROFINET master the telegram
is filled with the secured value and forwarded to the PROFIsafe device.
No further EL9930 needs to be plugged in behind the PROFIBUS/PROFINET master as the station ends
here. The other EK1100 is configured on a second EtherCAT master, therefore it doesn't need to be
considered.

In this application, unlike the previous example, an EL9930 must also be plugged in behind the PROFIBUS/
PROFINET master terminal and configured. The EtherCAT telegram leaves the station via an EK1100 to the
next EK1100 station.
Fig. 18: Valid PROFIsafe configuration with EL9930 - example 2
In this application an EL9930 must also be plugged in behind the PROFIBUS/PROFINET master terminal
and configured, as the EtherCAT telegram still leaves the station to the downstream EK1100 via an
EtherCAT cable.
