Configuring the Bulletin 2705 Keypad Module
with PLC Controllers
This chapter lists compatibility considerations for operating the Bulletin
2705 RediPANEL Keypad Module with programmable controllers via the
remote I/O link. Topics also include the remote I/O architecture and factors
in calculating rack size.
Bulletin 2705 Keypad Modules communicate with all Allen–Bradley
programmable controllers that support the remote I/O link.
The modules communicate with the PLC controllers through remote I/O
scanners and sub–scanners. The modules contain all of the necessary
electronics to connect directly to the remote I/O cable that originates from a
scanner or sub–scanner module. The scanners have both physical and logical
limitations. The physical limitations refer to the number of separate chassis
(I/O racks, drive systems, or RediPANEL Modules) the scanner can
accommodate. The logical limitations refer to the amount of I/O the scanner
can address.
To configure RediPANEL Modules with PLC controllers you need to know:
1. The appropriate scanner module for the PLC controller. This can be
found in the next section titled Remote I/O Architecture.
2. The amount of I/O the RediPANEL Module utilizes. This is found in the
section titled Calculating Rack Size on Page 4–7.
3. The number of chassis and amount of I/O that the scanner can
accommodate. This is found in the section titled Remote I/O
Configuration on Page 4–8.
