Digital I/O
The digital inputs and outputs are also connected via the 12-pin Weidmüller plug on the rear of the FAC 9400
IP. Neither input nor output is potentially separated.

SW latency
The sampling rate of the digital input is 40
ms. If the status of a digital input equals two
consecutive queries, then this status will be
adopted. I.e., a signal must be >= 80 ms
(pulse width.
