During operation, the operating system stores temporary data and parts of the user
program in the working memory.
■
With MRESET you can set the CPU to the Ready state without a power cycle. This
unloads the working memory, among others.
The parametrization memory as the sum of program and data memory provides memory
for:
■
Current firmware version
■
Overlay file system for user program, configurations, user data and firmware adjust-
ments.
Use of the overlay file system:
■
As soon as you configure the CPU or make changes to the current firmware version,
data are generated in the overlay file system.
■
By 'Resetting to the factory setting type 1', you can delete the overlay file system,
among others. The current firmware version remains, but all changes to it are dis-
carded.

■
By 'Resetting to the factory setting type 2', you can delete the overlay file system
and the current firmware version, among others. The current firmware version is over-
written by the original firmware version and the delivery state of the CPU is restored.
