Using this ManualThis Quick Reference provides information frequently needed for using and maintaining your Allen-BradleyPLC-5 processor.It is intended for reference purposes only, and not as the sole source of information.For more specific information on any topic in this Quick Reference, see: Enhanced and Ethernet PLC-5 Family Programmable Controllers User Manual, publication 1785-6.5.12 Classic PLC-5 User Manual, publication 1785-6.2.1 ControlNet PLC-5 Programmable Controllers Phase 1.5 User Manual, publication 1785-6.5.22Important User InformationBecause of the variety of uses for the products described in this publication, those responsible for the applicationand use of this control equipment must satisfy themselves that all necessary steps have been taken to assure thateach application and use meets all performance and safety requirements, including any applicable laws,regulations, codes and standards.The illustrations, charts, sample programs and layout examples shown in this guide are intended solely forpurposes of example. Since there are many variables and requirements associated with any particular installation,Allen-Bradley does not assume responsibility or liability (to include intellectual property liability) for actual usebased upon the examples shown in this publication.
The Safety Guidelines for the Application, Installation, and Maintenance of Solid State Control, publicationSGI-1.1 (available from your local Allen-Bradley office), describes some important differences betweensolid-state equipment and electromechanical devices which should be taken into consideration when applyingproducts such as those described in this publication.Reproduction of the contents of this copyrighted publication, in whole or in part, without written permission ofAllen-Bradley Company, Inc. is prohibited.Summary of ChangesIn 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 youare using, we refer you instead to the programming software documentation that accompanies your particularsoftware package. Of course, we still provide the essential reference information you need to quickly accomplishyour tasks, but if you have specific questions about software procedures, you should refer to your programmingsoftware documentation set.To help you find new information, we included change bars as shown to the left of this paragraph.
