Rockwell Automation 2705 REDIPANEL KEYPAD MODULE USER MANUAL - Manual (Page 9)

Chapter 2
Product Introduction
2–2
The Keypad Module combines the functions of standard thumbwheel or push
button devices with the built–in capabilities of a remote I/O rack.
The Keypad Module communicates directly with the programmable
controller via the Remote I/O link. You can install a 2705 module anywhere
along that link.
To the PLC, the Keypad Module looks like a hardwired remote I/O rack.
The function keys and the LED output signals are programmed as discrete
I/O in the PLC. Communication occurs through I/O image table updates.
Figure 2.1 shows a typical application.
