Windows Comparator

Four windows are available on the module. Each window can be used to detect when the input data of the selected mode is within or outside of a configured window. You tie windows to the encoder (HSC or SSI) and to as many as two module outputs.

The following figure shows an example of how a window controls output behavior, using HSC Count as the input data source for the window. For more information, see Controlled by Window. The windows can operate in different modes.

You can configure windows to operate in the following modes for HSC:

Count or scaled count
Frequency, instantaneous, scaled, or average
Acceleration, instantaneous, scaled, or average
Pulse Width, instantaneous or average

You can configure windows to operate in the following modes for SSI:
