14 Drive-based safety
The safety concept of the 8400 protec HighLine controller provides three safety options per design.
Safety option 10 (SO10):
• The drive-based safety implemented in the controller permits to connect external safety
components, e.g. passive sensors. Active sensors with self-testing signals can be directly
connected without using further components.
Safety option 20 (SO20):
• The drive is switched off safely by a higher-level safety PLC via PROFIsafe/PROFINET.
Safety option 30 (SO30):
• The safe disconnection can both be carried out by a higher-level safety PLC via
PROFIsafe/PROFINET and through the connection of active or passive sensors.

Note!
Safety options 20 and 30 can be parameterised via the »Engineer«.
The motion functions are continued to be executed by the controller. The drive-based
safety monitors the safe compliance with the limit values. When the limit values are
exceeded, the drive-based safety starts the control functions according to EN 60204-1
directly in the controller.
The safety functions are suitable for applications according to IEC 61508 to SIL 3 and
achieve the performance level (PL) e according to EN ISO 13849-1.
The requirements of the EN 954-1 standard which was valid until 30 November 2009 are
fulfilled for safety option 10 to control category 4 and for safety option 20 and 30 to
control category 3.
