Input filter for digital inputs
To suppress disruptions, you can configure an input delay for the digital inputs.
You can specify the following values for the input delay:
● None
● 0.05 ms
● 0.1 ms
● 0.4 ms
● 1.6 ms
● 3.2 ms (default setting)
● 12.8 ms
● 20 ms
Note
Shielding
If you use standard digital inputs with "None" set as the input delay, you must use shielded
cables. Shielding and the infeed element are recommended for use of standard digital inputs
starting from an input delay of 0.05 ms but are not absolute
ly necessary.
