then set again when the update message is received. We recommend that the reset time be a little
more than twice the update time.
To set an output reset time, select “Output Reset Times” on the left-hand menu and double-click the
selected input. The update time will be shown in days:hours:minutes:seconds. Change the values in
each field. The display also shows the maximum and minimum values.
Analog Sensitivity Configuration
The analog sensitivity is the change
required in an analog input before a
“Change Of State” is detected, and
the new analog value is transmitted.
For input signals which vary widely
over a short period of time or have a
normal oscillation, the analog
sensitivity should be set to an
appropriately large value. This
ensures that many change messages
are not transmitted in too short a
time. This will result in channel
congestion, as described in the
preceding section.
To change an analog sensitivity,
select “Sensitivities” on the left-hand menu and double-click the selected input. The sensitivity for
physical inputs is shown in
mA and internal input is
shown as %.
SetPoint Configuration
Setpoints allow a remote
digital output to be turned
on and off depending on
the value of an analog
input. The “set-point
status” internal input must
be mapped to an output for
this option to have effect.
When the AI is less than
the Low Set-point (LSP),
the set-point status will be
active (on, “1”) - when
the AI is more than the High Set Point (HSP), the set-point status will be reset (off, “0”). Note that the
High Set Point (HSP) must always be higher than the Low Set Point (LSP). For the -1 module, only
AI1 has set-point values. For -2 modules, all six analog inputs have set-points.
