1.4 Main features
● PROFINET IO interface with PROFIsafe protocol, for transfer of a safe position and velocity
● Fast process data channel via PROFINET IO, not safety instrumented
● Variant 1 only:
Additional incremental or SIN/COS or SSI interface, not safety instrumented
● Two-channel scanning system, for generation of safe measured data through internal channel
comparison
– Variant 1:
Channel 1, Master system:
Optical single-turn scanning via code disc with transmitted light and magnetic multi-turn
scanning
Channel 2, Test system:
Magnetic single- and multi-turn scanning
– Variant 2:
Channel 1, Master system:
Magnetic single- and multi-turn scanning
Channel 2, Test system:
Magnetic single- and multi-turn scanning
Channel 1 Master System data and Channel 2 Test System data are separately provided in the non
safety instrumented process data channel with normal PROFINET IO protocol (untested) and short
cycle time.
In “legacy mode”, controllers with 16-bit registers transfer safety-oriented data using the PROFIsafe
V2.4 Basic Protocol (BP). Other operating modes also use 32-bit position data and the safety-related
data can be transmitted either with the PROFIsafe V2.4 Basic Protocol (BP) or with the PROFIsafe
V2.6.1 Expanded Protocol (XP).
The inspection system is used for the internal safety check. “Safe data” obtained through two-channel
data comparison are packed into the PROFIsafe protocol and transmitted to the controller via the
PROFINET IO.
The optional incremental interface in Variant 1, or its alternative SIN/COS interface, are derived from
the master system and are not evaluated with respect to safety.
Instead of the incremental interface, a synchronous-serial absolute-value interface (SSI) is available,
which is also not evaluated with respect to safety.
