Summary of Changes
In this release of the PLC-5 Quick Reference, we have altered the way we reference software documentation.
Rather than show specific screens and key sequences which may vary according to the software package you
are using, we refer you instead to the programming software documentation that accompanies your particular
software package. Of course, we still provide the essential reference information you need to quickly accomplish
your tasks, but if you have specific questions about software procedures, you should refer to your programming
software documentation set.
To help you find new information, we included change bars as shown to the left of this paragraph.
