The user memory contains the logic and data blocks of the user program. The
user memory is integrated into the C7 CPU as a flash memory. However, the
user program is executed in the –> work memory of the C7 CPU.
The user program contains all the statements and declarations as well as data
for signal processing by which a plant or process can be controlled. It is
assigned to a programmable module (for example, C7 CPU, FM) and can be
structured in smaller units (blocks).
