Activating noise blanking increases the response time of the HIMatrix system!

The measures specified above are not necessary if the plant design precludes surges from
occurring within the system.
In particular, the design must include protective measures with respect to overvoltage,
lightning, earth grounding and plant wiring in accordance with the relevant standards and
the instructions specified in the System Manual (HI 800 141 or HI 800 191).
5.3.5 Configurable Digital Inputs
The digital inputs of the F35 controller and the MI 24 01 module operate as analog inputs,
but return digital values due to the configuration of switching thresholds.
For configurable digital inputs, the test routines and safety-related functions for analog
inputs apply as specified in Chapter
5.4.
5.3.6 Line Control
Line control is used to detect short-circuits or open-circuits and can be configured for the
HIMatrix systems with digital inputs (and not with configurable digital inputs), e.g., on
EMERGENCY STOP devices complying with Cat. 4 in accordance with EN 954-1.
To this end, connect the digital outputs (TO) of the system to the digital inputs (DI) of the
same system as follows (example):
DI 3 4
TO 1
2
DI 1
2
EMERGENCY STOP 1
EMERGENCY STOP 2
EMERGENCY STOP devices in accor-
dance with EN 60947-5-1 and
EN 60947-5-5
Figure 2: Line Control
The digital outputs TO 1 and TO 2 are pulsed (T1 and T2) to monitor the wire to the digital
inputs. The signals for the pulsed outputs must begin with DO[01].Value and reside in
direct sequence, one after the other (see system variables/signals in the manuals).
