Input delay
This parameter can be used to avoid signal faults. Changes to the signal are only detected if
they are constantly pending longer than the set input delay time.
Isochronous configuration is only possible if there is no input delay configured for at least
one channel. In isochronous mode, the terminal signal is read in at the time T
i
(time for
reading the input data). The read time T
i
refers to the channel for which no input delay time
was configured.
For input channels with longer input delays, the read time is moved accordingly. This means
individual channels can be assigned input delays, if necessary, without having a negative
impact on the possible cycle time.
Note
If you
select the "None" or "0.05 ms" option for the input delay, you have to use shielded
cables for connection of the digital inputs.
Hardware interrupt: rising edge
Specifies whether a hardware interrupt is generated for a rising edge.
Hardware interrupt: falling edge
Specifies whether a hardware interrupt is generated for a falling edge.
