Loading a Resource Configuration from the Flash Memory of the
Communication System
If data errors were detected in the NVRAM thus causing the watchdog time to be exceeded, it
can be useful to load the resource configuration from the flash memory for the communication
system instead of from the PADT:
If the Control Panel (CP) is no longer accessible, the connection parameters for the project must
be reset in the controller, see Chapter 7.3.7.
If the controller adopts the STOP/VALID CONFIGURATION state after restarting, the user
program can again be started.
If the controller adopts the STOP/INVALID CONFIGURATION state after restarting, the user
program must be reloaded into the NVRAM.
Use the
Load Configuration from Flash
command to read a backup copy of the last
executable configuration from the flash memory for the communication system transfer it to the
processor's NVRAM. At this point, select
Online -> Start (Cold Start)
to restart the user
program with no need to perform a download of the project.
