Quick Start for Experienced
Users
This chapter can help you to get started using the SLC 500 Modular
Processors. We base the procedures here on the assumption that you
have an understanding of SLC 500 products. You should understand
electronic process control and be able to interpret the ladder logic
instructions required to generate the electronic signals that control
your application.
Because it is a start-up guide for experienced users, this chapter does
not contain detailed explanations about the procedures listed. It
does, however, reference other chapters in this book where you can
get more information.
If you have any questions or are unfamiliar with the terms used or
concepts presented in the procedural steps, always read the
referenced chapters and other recommended documentation before
trying to apply the information.
This chapter:
•tells you what tools and equipment you need
•lists how to install and wire your power supply
•lists how to install and apply power to your processor
•lists how to establish communications with the processor
•describes how to return the SLC 5/03, SLC 5/04, and SLC 5/05
processors to initial factory conditions if required
Have the following tools and equipment ready:
•medium blade screwdriver
•programming equipment
•a 1747-PIC and 1747-CP3 programmer cable, or 1784-KT, -KTX,
-KT2, or -PCMK communication interface, or standard Ethernet
