Failsafe Timer Functionality

Overview

The Failsafe Timer tab configures the I/O failsafe timer. The Failsafe Timer is enabled on a global basis and provides a trigger mechanism that can be configured for each channel when no I/O traffic/management has occurred for the specified amount of time. A Failsafe Action can be configured for each Digital Output channel, each Serial Signal Output pin (DTR and RTS), and each Relay channel to either Activate or Deactivate the output.

The Failsafe Timer has a different function when I/O Extension is enabled for Digital Output channels, Relay channels, or the Serial Signal Output pins (DTR and RTS). For I/O Extension, the Failsafe Timer provides a per channel or per serial signal output pin trigger mechanism that is activated when there are no TCP sessions for the specified amount of time.
