Comparison of the checksums
As soon as you place safety components in your project, a checksum is automatically
calculated for your safety project. After the project transfer, the checksum of your project
and the CPU, which is connected online, must be identical. The checking procedure is as
follows:
1.
Establish an online connection to the CPU.
2.
Double-click on
‘SafetyPLC’
.
3.
Select the

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
■
