Debounce time operates
on the set-point status in
the same way as digital
inputs.
To change a setpoint
values, select “SetPoints”
on the left-hand menu and
double-click the selected
Setpoint Status.
Pulse Input Count
Configuration
PI1 of the 105-2 and 105-4
modules normally
count up to 100Hz (as
for the other PI’s),
however can be
configured to count up
to 1000Hz. This
configuration actually
divides the input count
by 10 - each count in
the PI1 register is then
equivalent to 10 input
pulses. If PI1 is
mapped to a PO, then
the maximum output
pulse rate is 100Hz,
however each output
pulse is equivalent to 10
input pulses.
To configure the “divide
by 10” feature, select
“Pulse Inputs” on the left-
hand menu and select the
“Count” page - double-
click “Pulse Input 1
Count” and enable
“divide by 10” counting.
Pulse Input Rate Scale
Configuration
When a pulse rate is
mapped to an analogue
output, the rate must be
scaled to the 4-20mA
output. The pulse rate scale is the rate (in Hz) corresponding to the maximum value (20 mA
