No.
b1-06
Setting 0: Read once (1 ms scan)
The state of a digital input is read once. If the state has changed, the input command is immediately processed. With this setting
the drive responds more quickly to digital inputs, but a noisy signal could cause erroneous operation.
Setting 1: Read twice (2 ms scan)
The state of a digital input is read twice. The input command is processed only if the state does not change during the double
reading. This reading process is slower than the "Read once" process, but it is more resistant to noisy signals.
