Each input signal has an update
time. If a change has not occurred
for this input within this time, then a
transmission is set for this input
after the update time has expired.
Each input signal has its own timer
- when a transmission occurs for
this input (either a change
transmission or an update
transmission) the timer is reset to
zero. If the timer reaches the
Update Time value, then a update
transmission occurs.
Digital inputs (both external inputs
and internal) have a separate
update time for their "off" state and
"on" state. This allows the input to
be reported differently depending
on its state. If the digital input is an
alarm, then a user may wish the input to be updated more frequently when in the alarm state than
when not in the alarm state. The analogue input and pulsed inputs only have one update time value.
Valid values are 10 seconds to 120 hours. If less than 10 seconds is entered, the value will default
to 10 seconds. If zero is entered, then there will be no update transmissions for this input.
4.3 Digital Inputs
Apart from update times, the
only configurable parameter
for digital inputs is the
paralysis time. This parameter
can be changed by selecting
the Unit details option.
If a value of zero is entered,
then there is no paralysis time.
4.4 Analogue Input
There are three parameters which
may be adjusted for the analogue
input.
The change sensitivity is the
amount of change since the last
