Hi,
I have 2 safety devices (Banner EZ LS light curtains and a Keyence GS-71 Interlock) that are giving me some difficulties. The plc is a Compact GuardLogix, with a 5069-IB8S input module. The safety program uses the DCS instruction for the e-stop, light curtains, and interlock. During operation, the DCS for the light curtains and for the interlock both post fault 32 (inputs changed state during execution of instruction).
From what I can tell, the OSSD outputs for the light curtains and interlock are pulsing as part of a self-testing procedure, which is what's causing the fault 32. If you know a way off-hand to stop that or account for it in the DCS instruction, how can I do that? If that could compromise the safety rating, what would be the proper way to program the safety controls for these devices?
