CIP Safety I/O for the GuardLogix Control System
Overview
Before operating a GuardLogix® safety system containing CIP Safety I/O
modules, you must read, understand, and follow the installation, operation, and
safety information provided in the publications listed in the SIL 3-certified
GuardLogix Components tables on page 14.
CIP Safety I/O modules can be connected to safety input and output devices,
allowing these devices to be monitored and controlled by the GuardLogix
controller. For safety data, I/O communication is performed through safety
connections using the CIP Safety protocol; safety logic is processed in the
GuardLogix controller.
Typical Safety Functions of
CIP Safety I/O Modules
The following is treated as the safe state by CIP Safety I/O modules:
• Safety outputs: OFF
• Safety input data to controller: OFF
The CIP Safety I/O modules should be used for applications that are in the safe
state when the safety output turns OFF.
