CPU Setup Information
Even if you have years of experience using PLCs, there are a few things you need to do before
you can start entering programs. This section includes some basic things, such as changing
the CPU mode, but it also includes some things that you may never have to use. Here’s a brief
list of the items that are discussed:
• Using Auxiliary Functions
• Clearing the program (and other memory areas)
• How to initialize system memory
• Setting retentive memory ranges
The following paragraphs provide the setup information necessary to get the CPU ready for
programming. They include setup instructions for either type of programming device you are
using. The D2–HPP Handheld Programmer Manual provides the Handheld keystrokes
required to perform all of these operations. The
Direct
SOFT Manual provides a description
of the menus and keystrokes required to perform the setup procedures via
Direct
SOFT.
