Chapter 4

Programming the RediPANEL Modules

4–9

When using a PLC-2/20 or 2/30 with a RediPANEL module, the system must

include a 1772-SD2 Remote I/O Scanner/Distribution Panel (or a 1771-SN

Sub I/O Scanner Module). The 1772-SD2 allows the PLCs to communicate

with as many as 16 remote I/O devices in any configuration totaling 7 logical

racks of I/O or less.

For details on 1771-SD2 wiring connections and switch settings, see

Publication No. 1772-2.18 (The Remote I/O Scanner/Distribution Panel).

Programming Example

Switch Bank #1 on the RediPANEL Module is set to use:

• Rack Address 2 (switch settings 1 - 6)

• Module Group 0 (switch settings 7 and 8)

Figure 4.1 shows typical address instructions and how these instructions are

used in your PLC-2/20 or 2/30 program.
