SafetyTag/ SafetyTask Issue Guardlogix

[Daffi 0]

I'm currently doing a Safety Program for a current project. However something is arising that I am just curious about. On an overall safety check rung which I have made RC60_Safety_Ok a controller safety global tag, every few seconds the tag seems to go high then low, a kind of fast flashing every 40/60 seconds. (See Safety rung Attachment). When I branch all inputs it keeps happening to the output RC60_Safety_Ok. That output is only wrttien to that rung and nowhere else.

I are putting it down to the periodic safetytask configuration. (See SafetyTask Config Attachment)

Obviously, this is causing me issues with the safety_ok losing signal in any routines that requires this tag. Has anybody any ideas why RC60_Safety_Ok keeps losing its signal?

Thanks in advance.

Can you post a screenshot of the R40 coil, the problem child that is causing this rung, R60 coil, to intermittently drop out?
