The DeviceNet Safety products meet the DeviceNet Safety specification published by the Open DeviceNet Vendor Association this year. As a result, the devices are designed to help assure fail-safe communication between safety nodes such as safety PLCs, I/O blocks and the safety devices wired to them. The DeviceNet Safety Scanner connects directly to the Allen-Bradley GuardPLC, allowing the controller to send and receive information from a broad spectrum of both standard and safety devices on a single DeviceNet network. The DeviceNet Safety Scanner and I/O modules are TÜV-certified for up to Safety Integrity Level (SIL) 3 and Category 4, and feature configurable solid-state outputs, making them well suited for highly distributed applications.
