The first section of a programmable controller is the processor. The
processor might be called the “brains” of the programmable controller. It
is divided into halves:
central processing unit
memory
CPU

Central Processing Unit
The Central Processor Unit (CPU) makes decisions about what the
processor does according to the program you write.
