5.2.4. Counting inputs (C)
The 4 digital inputs can also be used as counting inputs (C1…C4).
This function must be enabled by appropriate licensing (obtainable also retrospectively).
The counting inputs C1…C4 have quick filters, the unipolar inputs I5…I16 have a hysteresis. The
counting inputs are linked to the signals of the other unipolar inputs. There is no changeover.
Available configurations of the counting inputs:
Up/Down counter
Pulse/Direction counter
Quadrature decoder
One of the counting inputs can also be used as a capture input. This configuration requires 3 of the in-
puts (partially as a CNT input or CAPT input). The flanks for Up, Down or Pulse can be defined as ris-
ing and/or falling flanks.
Direction: High = Up; Low = Down
Examples for counters: Up/Down; Pulse/Direction; Encoder (A/B)
