Auxiliary Functions
Many CPU setup tasks involve the use of Auxiliary (AUX) Functions. The AUX Functions
perform many different operations, ranging from 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
Direct
SOFT 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
Direct
SOFT package.
The following table shows a list of the Auxiliary functions for the Handheld Programmer.
Clearing an Existing Program
Before you enter a new program, be sure to always clear ladder memory. You can use AUX
Function 24 to clear the complete program. You can also use other AUX functions to clear
other memory areas.
• AUX 23 — Clear Ladder Range • AUX 24 — Clear all Ladders • AUX 31 — Clear V-memory
Initializing System Memory
The DL06 Micro PLC maintains system parameters in a memory area often referred to as the
scratchpad
. In some cases, you may make changes to the system setup that will be stored in system
memory. For example, if you specify a range of Control Relays (CRs) as retentive, these changes
are stored in system memory. AUX 54 resets the system memory to the default values.
