Auxiliary Functions

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, copying programs to EEPROM in the handheld programmer, etc. They are divided into
categories that affect different system parameters. Appendix A provides a description of the
AUX functions.
You can access the AUX Functions from DirectSOFT or from the DL205 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.
The following table shows a list of the Auxiliary functions for the different CPUs and the
Handheld Programmer.
NOTE: The Handheld Programmer may have additional AUX functions that are not supported with the
DL205 CPUs.
