Digital Inputs & Relay Outputs Page
The
Digital Inputs & Relay Outputs
page allows the user to view or edit the configuration of
DigitalInput
and
RelayOutput
objects.
A
DigitalInput
object represents an
Alarm Input
port; a
RelayOutput
object represents one
Relay Output
port.
The panels composing this pane can be hidden or shown individually by clicking on the
[Hide] or [Show] text.
DIGITAL INPUTS PANEL
The
Digital Inputs
panel allows the user to view the configuration of
DigitalInput
objects.
The drop-down box in the upper area allows to select one
DigitalInput
object.
The lower area of the panel shows the properties of the selected object:
Field name
Description
Voltage Threshold
Type (amplitude) of signal. Possible values are:
n
TTL => threshold voltage = 1.5 V
n
5VCMOS => threshold voltage = 2.5 V
n
12V => threshold voltage = 6V
Timing Filter
The strength (time constant) of the deglitching filter. Possible
values are:
n
OFF => No filtering
n
10ms => Weak filtering: filters out transients shorter than 10
milliseconds
n
100ms =>Strongest filtering: filters out transients shorter than
100 milliseconds
Events Enabled
When true, any valid (= not filtered out) transition on the input
produces an event.
