About the Modules
Chapter 2
I/O Module Overview
The Guard I/O modules implement the CIP Safety™ protocol extensions over
EtherNet/IP networks and provide various features for a safety system.
Use the modules to construct a safety-control network system that meets the
following requirements, up to and including:
• Safety Integrity Level Claim Limit 3 (SIL CL 3), as defined in
IEC 61508
• Category 4 (CAT. 4), Performance Level e (PLe), as defined in
ISO 13849-1
Remote I/O communication for safety I/O data is performed through safety
connections that support CIP Safety over an EtherNet/IP network, and data
processing is performed in the safety controller.
A safety controller monitors the status and fault diagnostics of the I/O
modules through a safety connection by using a new or existing EtherNet/IP
network.
