If the reset time is less
than the update time,
then the output will reset
when the reset time
expires, and 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.
Analogue Sensitivity Configuration
The analogue sensitivity is the
change required in an analogue
input before a “Change Of
State” is detected, and the new
analogue value is transmitted.
For input signals which vary
widely over a short period of
time or have a normal
oscillation, the analogue
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 analogue 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
analogue 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 105-1 module, only AI1 has set-point values. For 105-2
modules, analogue inputs 1 - 4 have set-points.
