Input Delay; Output Delay - Siemens SIMATIC S5 Manual

General Operation
4.2.2

Input delay

The input delay of the 24 V inputs consists of two times:
• Delay of the input circuit:
• Debouncing time:
Remember:
For adaptation to simple sensors, the fast 24 V inputs can be debounced. You can configure the
debouncing time with the aid of COM 265.
4.2.3

Output delay

The output delay of the 24 V outputs is determined by the output wiring.
• Delay of the output wiring:
The following table gives an overview of possible output delays depending on the ohmic load of the
24 V output wiring.
