Safety Protocol CIP Safety
What is CIP Safety?
CIP Safety is a safety protocol for transmitting safety-critical data. The protocol is certified according to IEC 61508 for up to SIL3 and enables fast and safe communication without additional wiring.
ASi CIP Safety over Sercos Gateway
The CIP Safety over Sercos Gateway with integrated safety monitor can – as a CIP Safety Originator – reliably control and monitor safe drives with a CIP Safety connection without the need of an additional higher level safety controller. The CIP Safety gateway takes over the safe part and safely switches the drives off when needed.

CIP Safety over EtherNet/IP + ModbusTCP Gateway
The CIP Safety over EtherNet/IP gateway interfaces with a GuardLogix® safety controller from Rockwell Automation to exchange standard as well as safety I/O data. The safety program generally runs in the safety PLC. A safety program in the gateway can also monitor system components without the use of a safety PLC (optional).
