On the input lines of the device it is capable of generating Contact ID messages and
transmitting them by the ascending edge (L
→
H) and descending (H
→
L) edge. (The number
of the current input is signed here by’x’).
The length of the time frame can be configured by the
IDELAY
in 20 msec steps, which is
enabled
by default for the inputs to the ascending and descending edges without inverting in
a 500 msec time frame (here the delay value is 25 * 20msec).
The edges can be
enabled/disabled
by the
IxLHEN
(low-to-high) and
IxHLEN
(high-to-low)
parameters for every input line. The
direction
of the
edge detection
(ascending, descending)
can be reversed by the
IxINV
(as NO= Normal Open, NC=Normal Close) parameter.
At this time, the ascending and descending edges are filtered through a time frame (the
inputs must be hold for a minimal interval in the current status, to perform the further status
change while the change is acknowledged).
By the
IxARM
parameter, which is capable of granting that the current input line can
transmit signal only in
Armed
status (value is
Armed
), or whether it is useful to transmit
every status changes

even in
Disarmed
status (value is
24 hours

The
end of line resistor
can be configured by the
IxEOL
parameter for the current input, to
detect cable wiring cut (sabotage detection feature), which is the most important in case of
