System topology
A-2.1
General topology
A VersaSafe system can be integrated into various bus systems (e.g., PROFINET, and
PROFIBUS). The standard bus system is therefore supplemented by components to
achieve safety.

Control level
A standard control system is used as the controller (see also Section
"Network and controller requirements" on page 71).
I/O level
Safe devices are integrated into the VersaPoint station at I/O level. Safe and
standard devices can be operated simultaneously in the overall system.
Communication
Communication takes place via the standard control system and the
standard bus system using safe data packets.
System
The system consists of a standard control system and up to 31 VersaSafe
islands.
