COUNTER A RESET ACTION

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.

COUNTER A DECIMAL POSITION

This selects the decimal point position for Counter A and any setpoint value

assigned to Counter A. The selection will also affect Counter A scale factor

COUNTER A SCALE FACTOR

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.)

COUNTER A SCALE MULTIPLIER

The number of input counts is multiplied by the scale multiplier and the scale

only the scale factor affecting the display. (Details on scaling calculations are

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.)

Module 1 is the programming for Counter A, Counter B and the Prescaler Output. Counter B parameters follow the Prescaler parameters. For

maximum input frequency, the counters should be set to mode NONE and the Prescaler to NO when they are not in use. When set to NONE

or NO, the remaining related parameters are not accessible. A corresponding annunciator indicates the counter being shown in the Display

Mode. An Exchange Parameter Lists feature for scale factors and count load values is explained in Module 2.
