The Allen-Bradley CompactBlock Guard I/O on EtherNet/IP lets you use standard EtherNet/IP protocol with a GuardLogix controller or other Safety PLC that incorporates the CIP Safety protocol over EtherNet/IP. Safety PLC systems, including Safety I/O, lets manufacturers deploy safety applications with programmable controllers as opposed to the traditional approach of using hard-wired safety relays. Safety networks distribute the safety I/O, reducing wiring and installation costs, while making diagnostic information available to the standard control and HMI system.

CompactBlock Guard I/O on EtherNet/IP detects failures at the I/O and field-device level. It communicates over the EtherNet/IP network using the CIP Safety protocol, making it compatible with standard Ethernet infrastructure devices, including wired and wireless products.

The Guard I/O family includes a full suite of products that connect to DeviceNet for in-cabinet and on-machine applications.
