On Change Channel

Overview

On Change Channels are used to monitor multiple input channels for changes.

If any of the input channels change, the value of the On Change output changes from 0 to 1.

This is useful for example, for monitoring mode switches; when one of the modes changes, the On Change output can be used as an event to trigger a jump to a page showing more information about the changing mode.

Options

Revert if no change after [s]

Once triggered, the On Change Revert shall be triggered after the Revert timeout has elapsed.

Initial delay after power on [s]

Following a power-up or system reset, the Initial Delay prevents the On Change channel from producing a value.

Remarks

When an On Change output is created, a hidden On Change Revert channel is created using the name of the On Change output with a _Revert suffix. This output is a logical not of the On Change channel and can be used to revert back to the original screen once the output has stopped changing.
