To enter data you must first key in the desired numbers using the numeric
keypad. The data will appear on the right hand side of the display as the
numbers are being keyed. To complete data entry you must press the
ENTER key. The entered data is placed directly into the data word(s) of the
Input Image table. Any ASCII characters in the left hand side of the display
remain there during data entry, unless the Split Display feature is enabled.
Split Display
This feature controls the display during operator entry. Split display must be
enabled (DIP switch 4 on switch bank #3) and DM=0.
When the operator starts entering data, the data shown in the right half of
display is placed in the left half. The operator can then enter new data in the
right half.
Decimal Modes
The decimal point key allows you to input decimal numbers. You control the
position of the decimal point, either fixed or floating, by setting bits in the
output image table. See Chapter 7 for input and output image tables.
Polarity
The polarity key (minus sign) allows you to change the polarity of numbers.
The minus sign uses one character position, limiting negative numbers to
seven digits.
Destination Entry
The keypad module has an additional entry feature known as the destination
function. This feature is selected by DIP switch 2 on switch bank #2. It is
typically used to load data values into multiple locations, such as a series of
timer/counter presets, loop setpoints, etc.
This function uses the destination word and destination bits in the Input
Image table. The keypad operator enters a destination number that defines
which timer, counter, or PLC memory location is to be accessed. The
operator can then enter new data or monitor the present data in that timer,
counter, or PLC memory location
