The memory card serves as external storage medium. There may be stored several proj-
ects and sub-directories on a memory card. Please regard that your current project is
stored in the root directory and has one of the following file names:
n
S7PROG.WLD
n
AUTOLOAD.WLD
1.
Create in the Siemens TIA Portal a wld file with
‘Project
è
Memory card file
è
New’
.
ð
The wld file is shown in the
Project tree
at "SIMATIC Card Reader" as "Memory
card file".
2.
Copy the blocks from the
Program blocks
to the wld file. Here the hardware configu-
ration data are automatically copied to the wld file as "System data".
The transfer of the application program from the memory card into the CPU takes place
depending on the file name after an overall reset or PowerON.
n
S7PROG.WLD
is read from the memory card after overall reset.
n
AUTOLOAD.WLD
is read from the memory card after PowerON.
The blinking of the MC LED of the CPU marks the active transfer. Please regard that your
user memory serves for enough space for your user program, otherwise your user pro-
gram is not completely loaded and the SF LED gets on.
When a memory card has been installed, the write command stores the content of the
RAM as S7PROG.WLD on the memory card. The write command can be found in the
Siemens TIA Portal in the Task card "Online tools" in the command area at "Memory" as
button [Copy RAM to ROM]. The MC LED blinks during the write access. When the LED
expires, the write process is finished. If this project is to be loaded automatically from the
memory card with PowerON, you have to rename this to on the memory card to
AUTO-
LOAD.WLD
.
Please note that in the Siemens TIA Portal with some CPU types the
[Copy RAM to ROM] button is not available. Instead please use the CMD
auto command SAVE PROJECT.

After accessing the memory card you can find a diagnostics entry in the CPU. To monitor
the diagnostics entries, you select
Online & Diagnostics
in the Siemens TIA Portal. Here
you can access the "Diagnostics buffer".
