Setting the Autoload Feature
You use the "Autoload" feature of WinAC Slot 41x to define how WinAC Slot 41x
reacts to a Power Up of the PC. This feature is particularly useful during the
commissioning phase of the automation system, or in unbuffered operation of the
CPU 41x-2 PCI. The Autoload feature enables you to configure the controller to
perform the following actions upon restart:
•
Load a STEP 7 user program that was previously archived
•
Set the operating mode to a defined state after loading the STEP 7 user
program
The topic Archiving and Restoring STEP 7 User Programs describes how to
archive a STEP 7 user program that can be configured as the autoload program.
To use the Autoload feature, your system must meet these requirements:
•
No FLASH card is plugged into the CPU 41x-2 PCI
•
The CPU 41x-2 PCI is operated without a backup battery
•
An external, independent 24 VDC supply is not connected
•
An archive file (.wld file) exists
