3.6 Digital inputs
3.6.1 LF pulse and signalinputs
The maximum counting frequency of the digital inputs can be adjusted us-
ing the "enSuite" software. The limit values specified for frequency and du-
ration shall only apply if the so-called "software debounce" has been
switched off.
The software debounce is activated ex-works to suppress interference
pulses and therefore restrict safe readings to 2 Hz.
If the software debounce is parameterized to a frequency
higher than 2 Hz, then it may lead to counting errors
caused by electromagnetic interference under certain cir-
cumstances.
