Parameter Assignment/Addressing - Siemens SIMATIC ET 200AL System Manual

Parameter assignment/addressing

To set up an automation system, you will need to configure, assign parameters and interlink
the individual hardware components. In STEP 7, the work needed for this is undertaken in
the device, topology and network view.
Configuring
"Configuring" is understood to mean arranging, setting and networking devices and modules
within the device, topology or network view.
An I/O address is automatically assigned to each module. The I/O addresses can be
subsequently modified.
The CPU compares the configuration preset in STEP 7 with the actual current configuration
of the system. In this way, potential errors can be detected and reported straight away.
The exact procedure for configuring devices is described in detail in the STEP 7 online help.
Assigning parameters
"Assigning parameters" is understood to mean setting the properties of the components
used. The settings for the hardware components and for data communication are configured
at the same time.
In STEP 7, you can "assign parameters" for the following settings PROFINET:
● Device names and IP address parameters
● Port interconnection and topology
● Module properties / parameters
The parameters are loaded into the CPU and transferred to the corresponding modules
when the CPU starts up. Modules are easy to replace from spare parts, as the parameters
assigned for the SIMATIC CPUs are automatically loaded into the new module at each
startup.
