Product Introduction
2–3
The 2705 RediPANEL Keypad Module features a numeric keypad with
DELETE, ENTER, decimal and polarity keys. Using the keypad, operators
can enter up to eight (8) digits (seven digits for signed numbers), which
appear on the right side of the 16 character display. If an attempt is made to
enter more than eight digits, only the first eight are accepted.
If mistakes are made while entering data, the display can be cleared one
character at a time by depressing the DELETE key. The data is not
transmitted to the PLC until the ENTER key is depressed. The DECIMAL
POINT key allows operators to enter decimal numbers.
Six user–definable function keys are also provided. These keys can be used
for:
•
Any momentary push button function.
•
Acknowledging alarm messages.
Each function key features an independent LED.
A terminal block is provided for hardwiring a security keyswitch. When the
Normally Open contact is closed, it locks out the functionality of the numeric
keypad, but allows the use of the function keys 1 through 6 and destination
value functions.
The RediPANEL Keypad Module features a sixteen character, alphanumeric,
vacuum fluorescent display. It can display input information from the
keypad, ASCII and numeric data from the PLC, and messages that are stored
in the module.
The module can display any one of the following combinations of
information at any one time:
1) All ASCII data. This can consist of either:
a) A single–line, 16 character message stored inside the module. Up to
120 single line messages can be stored in the EEPROM inside the
module. To create and edit messages, the modules feature a built–in
message editor. The editor is accessed by plugging an IBM–XT/AT
keyboard (or compatible) into the receptacle located on the back of the
module.
b) Up to 12 ASCII characters from the PLC.
In this manner, the Keypad Module can display text to inform and prompt
operators. It can also be used to display alarm messages that are stored on
the keypad’s EEPROM inside the module.
