7.1 Address assignment
7.1.1 Addressing - Overview
Introduction
In order to address the automation components or I/O modules, unique addresses must be
assigned to them. The various address areas are explained below.
I/O address
I/O addresses (input/output addresses) are required to read inputs and set outputs in the
user program.
Input and output addresses are assigned automatically by STEP 7 when modules are
inserted. Each module uses a continuous area in the input and/or output addresses
corresponding to its volume of input and output data.
Figure 7-5 Example with input / output addresses from STEP 7
The address areas of the modules are assigned by default to the Process image partition 0
("Automatic updating"). This process image partition is updated in the main cycle of the CPU.
Device address (e.g., Ethernet address)
Device addresses are addresses of programmable modules with interfaces to a subnet
(e.g., IP address or PROFIBUS address). They are required in order to address the various
devices on a subnet, e.g., in order to download a user program.
