Introduction
Many CPU setup tasks involve the use of Auxiliary (AUX) Functions. The AUX
Functions perform many different operations, including clearing ladder memory,
displaying the scan time, and copying programs to EEPROM in the handheld
programmer. They are divided into categories that affect different system resources.
You can access the AUX Functions from DirectSOFT
or from the D2–HPP
Handheld Programmer. The manuals for those products provide step-by-step
procedures for accessing the AUX Functions. Some of these AUX Functions are
designed specifically for the Handheld Programmer setup, so they will not be
needed (or available) with the DirectSOFT package. Even though this Appendix
provides many examples of how the AUX functions operate, you should supplement
this information with the documentation for your choice of programming device.
Note, the Handheld Programmer may have additional AUX functions that are not
supported with the DL05 PLCs.
