1.4 Main features
● EtherNet/IP™ – interface with CIP Safety™ protocol, used to transfer a safe position and a safe
velocity
● Fast process data channel via EtherNet/IP™, non-safety-related
● Variant 1 only:
Additional incremental or SIN/COS or SSI interface, non-safety-related
● 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
● One common drive shaft
The untested Channel 1 Master System data and the Channel 2 Test System data are separately
provided in the non-safety-related process data channel with normal EtherNet/IP™ protocol and short
cycle time.
The inspection system is used for the internal safety check. “Safe data” obtained through two-channel
data comparison are packed into the CIP Safety™ protocol and transmitted to the controller via
EtherNet/IP™.
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.
