The release allows companies to use the widely recognized industry standard EtherNet/IP protocol in conjunction with an Allenhe traditional approach of using hard-wired safety relays, the company said. Safety networks allow manufacturers to distribute the safety I/O, reduce wiring and installation costs, and make 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, while enhancing operator protection in many applications including robotic, point-of-operation, guard-monitoring and remote control applications. It communicates over the EtherNet/IP network using the industry standard CIP Safety protocol, making it compatible with standard Ethernet infrastructure devices, including wired and wireless products. Manufacturing and process customers can control and monitor the equipment’s safety devices with one of the CompactBlock Guard I/O modules, using the same data network for general automation control and factory-floor business systems, the company said in the December announcement.
