The figures on the following pages show the input and output tables for the
Keypad Module.
The following symbols and abbreviations appear in the input and output
tables. Refer to this list for identifying specific bits in the tables:
“-” Represents a “0”. No function is assigned for this bit location.
H H andshake bit. Refer to page 7–28 for more information.
EN EN ter bit. This bit toggles when the ENTER key of the keypad
module is depressed.
F1-F6
F
unction key bits. These bits are input signals from the function
keys. When one of the function keys is depressed the
corresponding bit will toggle.
L1-L6
L
EDs located on each function key. These bits are output signals
that feedback to acknowledge a function key was depressed.
They can be used like pilot lights. When bit=1 the LED is ON,
when bit=0 the LED is off.
DMD isplay M essage. This bit allows a 16–character stored message
to be displayed or ASCII data (No PLC numeric data), when
DM=1. Refer to Chapters 6 & 7 for more information.
SMD
S
tored M essage D isplay number. This is the output word
location for the message number which is being displayed
on the Keypad. When SMD=0, then ASCII data will be
displayed.
!
ATTENTION: Any SMD value greater than 120 will cause a
lock–up condition. To protect against this condition, a boundary
check should be used in the PLC program to help insure a valid
MSG # is sent.
