7.5.47.1 On-delay
If the on-delay is set, a signal change at the input DIGDELx-IN from LOW to HIGH is passed on to
the DIGDELx-OUT output after the delay time set under C0721 or C0726 has elapsed.

In this function, the time-element operates like a retriggerable monoflop:
• A LOW-HIGH edge at the input DIGDELx-IN starts the time element.
• If the delay time set under C0721 or C0726 has elapsed, the output DIGDELx-OUT is set to
HIGH.
• The time element is reset and the output DIGDELx-OUT is set to LOW with a HIGH-LOW edge
at the input DIGDELx-IN.
7.5.47.2 Dropout delay
A dropout delay causes a signal change at the input DIGDELx-IN from HIGH to LOW to be passed
on to the output DIGDELx-OUT if the delay time set under C0721 or C0726 has elapsed.

• A LOW-HIGH edge at the input DIGDELx-IN causes the output DIGDELx-OUT to be set to
HIGH and the time element to be reset.
• The time element is started with a HIGH-LOW edge at the input DIGDELx-IN.
• After the delay time set under C0721 or C0726 has elapsed, the output DIGDELx-OUT is set to
LOW.
