The memory system, as mentioned before, is composed of two major
sections—the system memory and the application memory—which in turn
are composed of other areas. Figure 5-6 illustrates this memory organization,
known as a memory map. Although the two main sections, system
memory and application memory, are shown next to each other, they are not
necessarily adjacent, either physically or by address. The memory map shows
not only what is stored in memory, but also where data is stored, according
to specific locations called memory addresses. An understanding of the
memory map is very useful when creating a PLC control program and
defining the data table.

Although two different programmable controllers rarely have identical
memory maps, a generalized discussion of memory organization is still valid
because all programmable controllers have similar storage requirements. In
general, all PLCs must have memory allocated for four basic memory areas,
which are as follows:
• Executive Area. The executive is a permanently stored collection of
programs that are considered part of the system itself. These supervisory
programs direct system activities, such as execution of the
control program, communication with peripheral devices, and other
system housekeeping activities.
