PI Pulse Input
Hints
If it is necessary to turn off a device when the pulse counter is placed in HOLD, it is recommended that you
also tie the source of the input HOLD signal to a DO block. The DO block would then control the On/off
State of the device.

Description
Execution Order for
Block.
This is the rack
address of the PFQ
module.
Module address of
the PFQ module.
Channel on selected
Module.
Example: if
measuring gallons
and if 100 pulses = 1
gallon, enter 100.
The output RATE is
calculated by
counting number of
pulses per Sample
Time and scaling it to
EU/Time Period.
Sample Time is a
rolling window of
time (updated each
scan cycle) used to
count pulses. The
longer the Sample
Time the smoother
the rate output and
the longer it will take
to change; the
smaller the Sample
Time the noisier the
rate output but the
quicker the
response.
Time unit used to
scale the rate from
pulses per Sample
