The number of input counts is multiplied by the scale multiplier and the scale
factor to obtain the desired process value. A scale multiplier of 1 will result in
only the scale factor affecting the display. (Details on scaling calculations are

DESCRIPTION
Does not count.
Adds Input A falling edge.
Adds Input A falling edge if Input B is high.
Subtracts Input A falling edge if Input B is low.
Adds Input A falling edge if User 1 is high. Subtracts
Input A falling edge if User 1 is low.
Adds Input A rising edge when Input B is high.
Subtracts Input A falling edge when Input B is high.
Adds Input A rising edge when Input B is high and
Input A falling edge when Input B is low. Subtracts
Input A falling edge when Input B is high and Input A
rising edge when Input B is low.
Adds Input A rising edge when Input B is high, Input
A falling edge when Input B is low, Input B rising
edge when Input A is low, and Input B falling edge
when Input A is high. Subtracts Input A falling edge
when Input B is high, Input A rising edge when Input

This enables the prescaler output. The prescaler output is useful for providing
a lower frequency scaled pulse train to a PLC or another external counter. On
each falling edge of Input A, the prescaler output register increments by the
prescaler scale value ( ????? ). When the register equals or exceeds 1.0000, a
pulse is output and the register is lowered by 1.0000. The prescaler register is
reset to zero whenever Counter A is reset (except for Setpoint Counter Auto
Reset). (See Prescaler Output Figure.)

When Counter A is reset, it returns to zero or Counter A count load value.
This reset action affects all Counter A resets, except the Setpoint Counter Auto
Reset in Module 6.

The prescaler output frequency is the Input A frequency times the prescaler
scale value.

* Factory Setting can be used without affecting basic start-up.
The number of input counts is multiplied by the scale factor and the scale
multiplier to obtain the desired process value. A scale factor of 1.00000 will
result in the display of the actual number of input counts. (Details on scaling
calculations are explained at the end of this section.)
