Auxilliary Functions
AUX 72 copies information from the EEPROM installed in the Handheld
Programmer to CPU memory in the DL05. You can copy different portions of
EEPROM (HP) memory to the CPU memory as shown in the previous table.
AUX 73 compares the program in the Handheld programmer (EEPROM) with the
CPU program. You can compare different types of information as shown previously.
AUX 74 allows you to check the EEPROM in the handheld programmer to make sure
it is blank. It’s a good idea to use this function anytime you start to copy an entire
program to an EEPROM in the handheld programmer.
AUX 75 allows you to clear all data in the EEPROM in the handheld programmer.
You should use this AUX function before you copy a program from the CPU.
You can use AUX 76 to quickly determine what size EEPROM is installed in the
Handheld Programmer.
AUX 8* — Password Operations
There are several AUX functions available that you can use to modify or enable the
CPU password. You can use these features during on-line communications with the
CPU, or, you can also use them with an EEPROM installed in the Handheld
Programmer during off-line operation. This will allow you to develop a program in the
Handheld Programmer and include password protection.

AUX 82 — Unlock CPU

AUX 83 — Lock CPU
You can use AUX 81 to provide an extra measure of protection by entering a
password that prevents unauthorized machine operations. The password must be
an eight-character numeric (0–9) code. Once you’ve entered a password, you can
remove it by entering all zeros (00000000). (This is the default from the factory.)
Once you’ve entered a password, you can lock the CPU against access. There are
two ways to lock the CPU with the Handheld Programmer.
S
The CPU is always locked after a power cycle (if a password is present).

You can use AUX 82 and AUX 83 to lock and unlock the CPU.
