WARNING
Risks with changes to filter time for digital input channel
If the filter time for a digital input channel is changed from a previous setting, a new "0"
level input value may need to be presented for up to 12.8 ms accumulated duration before
the filter becomes fully responsive to new inputs. During this time, short "0" pulse events of
duration less than 12.8 ms may not be detected or counted.
This changing of filter times can result in unexpected machine or process operation, which
may cause death or serious injury to personnel, and/or damage to equipment.
To ensure that a new filter time goes immediately into effect, cycle the power of the CPU.
