Chapter 4
Programming the RediPANEL Modules

4–14

The PLC-5/15 and 5/25 processors have built-in remote I/O scanners. No
additional hardware is required. Run the two conductor shielded cable (Blue
Hose) from the RediPANEL to the remote I/O port of the PLC-5.

To use the built-in scanner:

Set switch 8 in DIP Switch Bank SW-1 on the processor to the OPEN,
OFF or Scanner Mode position.

Set the baud rate on the RediPANEL module to 57.6K baud for a
PLC-5/15 or -5/25.

For an enhanced processor the baud rate can be 57.6K, 115.2K or 230.4K.

Programming Example

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

Rack Address 3 (switch settings 1 - 6)

Module Group 4 (switch settings 7 and 8)

Figure 4.4 shows typical address instructions and how these instructions are
used in your PLC-5/15 or -5/25 program.
