Fig.114: Invalid PROFIsafe configuration - sample 1
The following configuration is not permitted according to the PROFIsafe policy, since the PROFIsafe
telegram leaves the EK1100 via EtherCAT, is received on the second EK1100 and is only then sent to the
PROFIsafe slave via PROFIbus.

4.13 TwinSAFE SC configuration
The TwinSAFE SC technology enables communication with standard EtherCAT terminals via the Safety over
EtherCAT protocol. These connections use another checksum, in order to be able to distinguish between
TwinSAFESC and TwinSAFE. Eight fixed CRCs can be selected, or a free CRC can be entered by the user.
By default the TwinSAFE SC communication channel of the respective TwinSAFE SC component is not
enabled. In order to be able to use the data transfer, the corresponding TwinSAFE SC module must first be
added under the Slots tab. Only then is it possible to link to a corresponding alias device.
