On to Off Delay
An input signal is treated as Logic 1 during the On to Off delay time after the
falling edge of the input contact.
The input turns off only if the input contact remains off after the On to Off delay
time has elapsed. This setting helps to prevent rapid changes of the input data due
to contact bounce.
You can delay the On to Off transition by the following times:
• 0 ms
• 1 ms
• 2 ms
• 5 ms
• 10 ms
• 20 ms
• 50 ms

Data Transfer at RPI
The safety input module always sends data to the owner-controller at the RPI.
You set the RPI on the Connection page of the Module Properties dialog box in
the Logix Designer application.
Module Health Diagnostic
Every I/O module has a status indicator on the front of the module that indicates
module health.
For more information on status indicators, see Appendix A, Troubleshoot Your
Module on page 103 .
