COUNTER A DECIMAL POSITION
This selects the decimal point position for Counter A. The selection will
also affect Counter A scale factor calculations.
COUNTER A SCALE FACTOR
The number of input counts is multiplied by the scale factor to obtain
the desired process value. A scale factor of 1.0000 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 B DECIMAL POSITION
This selects the decimal point position for Counter B. The selection will
also affect Counter B scale factor calculations.
COUNTER A COUNT LOAD VALUE
Counter A resets to this value if Reset to Count Load action is
selected. To enter a negative Count Load value, increment digit 6 to
display a “-” sign.*

COUNT MODE
Select the count mode that corresponds with your application. The
input actions are shown in the boxes below. For simple counting
applications, it is recommended to use Count with Direction for the count
mode. Simply leave the direction input unconnected.
Shaded area selections only apply when Counter B is enabled (Dual
Count mode or batch counter).

Note: The Rate indicator signal is derived from Input A in all count modes.
COUNTER A RESET ACTION
When Counter A is reset, it returns to Zero or Counter A Count Load
value. This reset action applies to all Counter A resets, except a Setpoint
generated Counter Auto Reset programmed in Module 4.
COUNTER B BATCH COUNT ENABLE
The Counter B Batch Count function internally counts the number of
output activations of the selected setpoint(s). The count source for the
batch counter can be SP1, SP2 or both. Batch counting is available in
all count modes except Dual Counter, which uses an external input
signal for Counter B.
COUNTER A COUNT DIRECTION
Reverse (
) switches the normal Counter A count direction shown
in the Count Mode parameter chart.
*For value entry instructions, refer to selection/value entry in the
Programming The Meter section.
