About the Modules
Follow these instructions when wiring modules.
• Do not place communication lines and I/O lines in the same wiring duct
or track as high voltage lines.
• Wire correctly after confirming the signal names of all terminals.
• Follow torquing specifications as indicated in the installation instructions.
When cleaning modules, do not use the following:
• Thinner
• Benzene
• Acetone
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
requirements up to Safety Integrity Level 3 (SIL 3) as defined in IEC 61508,
Functional Safety of Electrical, Electronic, and Programmable Electronic
Safety-related Systems, and the requirements for Safety Category 4 of the
EN 954-1 standard, Safety of machinery - Safety related parts of control systems.
Remote I/O communication for safety I/O data are performed through safety
connections supporting CIP safety over an EtherNet/IP network, and data
processing is performed in the safety controller.
The status and fault diagnostics of the I/O modules are monitored by a safety
controller through a safety connection by using a new or existing EtherNet/IP
network.
