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 historically meant connecting auxiliary contacts from each safety input device to the PLC increasing costs due to the need for additional input cards, and increased installation time to hard wire each auxiliary contact to the allocated input. GuardLink provides both safety information and diagnostics through the same cable, with the diagnostics available via EtherNet/IP™, reducing the amount of wiring required for the safety system, and the cost and time to install the solution.
