Allen-Bradley Guardmaster has introduced Guardlink™, to simplify the connection of safety input devices, whilst providing diagnostics. Series connection of safety input devices is common practice in safety-related control systems. However, when the system trips, fault finding can be difficult due to the lack of diagnostic information. Providing diagnostics typically required additional wiring, increasing complexity, installation time and cost. GuardLink™ is a safety linking technology that simplifies this by providing safety and diagnostic information through the same cable. Connected to a safety relay and using an EtherNet/IP Network Interface, this information is easily passed through to the control system for increased diagnostics, which improves performance, reduces downtime on the machine, and links safety to The Connected Enterprise.
