Chapter 10

The rungs used in this example illustrate the programming principles of
chapters 5 through 7 of this manual. Of course, user application
programming may vary widely from this example. In any case, certain
types of support programming should be used in any program for a
command at a station. Support programming for each command includes:

START bit LATCH and UNLATCH control
REMOTE/LOCAL FAULT bit monitoring

Each of these parts of the program is shown in Figure 10.1.

Forms shown in Figure 10.7 to Figure 10.9 are available for programmer
documentation:

Switch settings - Communication Adapter Module (cat. no. 1771-KA2),

form 5030

Command Listing - From station, form 5032
Command Listing - To station, form 5033

These forms should be a part of the standard documentation at each
station that uses a programmable controller.

Forms are available in quantity through Catalog Services, Allen-Bradley
Co., Milwaukee, Wisconsin 53129

For quick reference, a map of the memory organization for each Bulletin
1772 Mini-PLC-2/15, PLC-2/30, and Mini-PLC-2/05 Programmable
Controller is included here. These maps should be used in conjunction
with the recommendations of chapter 4, concerning communication
adapter module access to memory areas.

Figures 10.2 through 10.6 show the memory organization for each
Controller.
