Archiving and Restoring STEP 7 User Programs
The memory card can only be removed and inserted when the PC is open.
However, you have the option of reading STEP 7 user programs from the CPU
41x-2 PCI or saving them to the CPU 41x-2 PCI without having to remove and
insert the memory card:
•
The
File > Archive from CPU
command is used to load the STEP 7 user
program and the hardware configuration from the load memory area of the
CPU 41x-2 PCI to the PC (memory card file).
•
The
File > Restore to CPU
command is used to load a STEP 7 user program
and the hardware configuration from the PC (memory card file) to the load
memory area of the CPU 41x-2 PCI.
•
With the
CPU > Options > Autoload
command, the PC retrieves a memory
card file that you have preselected and loads it onto the load memory area of
the CPU 41x-2 PCI following a Power On. Then, the CPU 41x 2 PCI switches
to the operating mode stored in the Memory Card file.
Archiving from CPU
The
File > Archive
function can be used to save the STEP 7 user program and the
hardware configuration located on the CPU 41x-2 PCI to the PC. The controller
panel reads out the load memory of the CPU 41x-2 PCI and stores this file with the
extension *.wld on the hard disk.
This file (memory card file) contains the STEP 7 user program and the current
hardware configurations (SDBs).
This function is also supported in SIMATIC Manager with
File > Memory Card
File
