Table. 8.5 - 265. Digital input settings of DI8 module.

Step Default
Description
DIx
Polarity
0: NO (Normally
open)
1: NC (Normally
closed)
-
0: NO
Selects whether the status of the digital input is 1 or 0 when the input is
energized.
DIx
Activation
threshold
16.0…200.0 V
0.1 V
88 V
Defines the activation threshold for the digital input.
When "NO" is the selected polarity, the measured voltage exceeding this
setting activates the input. When "NC" is the selected polarity,
the measured voltage exceeding this setting deactivates the input.
DIx
Release
threshold
10.0…200.0 V
0.1 V
60V
Defines the release threshold for the digital input.
When "NO" is the selected polarity, the measured voltage below this
setting deactivates the input. When "NC" is the selected polarity,
the measured voltage below this setting activates the input.
DIx
Activation
delay
0.000…1800.000
s
0.001
s
0.000 s
Defines the delay when the status changes from 0 to 1.
DIx Drop-
off time
0.000…1800.000
s
0.001
s
0.000 s
Defines the delay when the status changes from 1 to 0.
DIx AC
Mode
0: Disabled
1: Enabled
-
0:
Disabled
Selects whether or not a 30-ms deactivation delay is added to take the
alternating current into account. The "DIx Release threshold" parameter is
hidden and forced to 10 % of the set "DIx Activation threshold" parameter.
DIx
Counter
0…2
32
–1
1
0
Displays the number of times the digital input has changed its status from
0 to 1.
DIx Clear
counter
0: -
1: Clear
-
0: -
Resets the DIx counter value to zero.
The user can set the activation threshold individually for each digital input. When the activation and
release thresholds have been set properly, they will result in the digital input states to be activated and
released reliably. The selection of the normal state between normally open (NO) and normally closed
(NC) defines whether or not the digital input is considered activated when the digital input channel is
energized.
The diagram below depicts the digital input states when the input channels are energized and de-
energized.
