AUX 7* — EEPROM Operations
The following auxiliary functions allow you to move the ladder program from one
area to another and perform other program maintenance tasks.
Many of these AUX functions allow you to copy different areas of memory to and
from the CPU and handheld programmer. The following table shows the areas that
may be mentioned.
Option and Memory Type DL105 Default Range
1:PGM — Program $00000 -- $02047
2:V — V--memory $00000 -- $03777
3:SYS — System Non-selectable copies
system parameters
4:etc (All)— Program, Sys-
tem and non-volatile V--
memory only
Non-selectable
AUX 71 copies information from the CPU memory to an EEPROM installed in the
Handheld Programmer.You can copy different portions of EEPROM (HP) memory to
the CPU memory as shown in the previous table.
AUX 72 copies information from the EEPROM installed in the Handheld
Programmer to CPU memory in the DL105. 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.
