Configuring - Siemens SIMATIC S7-1500/ET 200MP System Manual

Configuring

Introduction
By configuring the individual hardware components, assigning their parameters, and
connecting them, you communicate to the S7-1500 automation system/ET 200MP distributed
I/O system its preset configuration and operating principle. You perform the work needed for
this in the device and network views in STEP 7.
"Configuring" is understood to mean the arranging, setup and networking of devices and
modules within the device view or network view of STEP 7. STEP 7 graphically represents
modules and racks. Just like "real" module racks, the device view allows the insertion of a
defined number of modules.
When the modules are inserted, STEP 7 automatically assigns the addresses and a unique
hardware identifier (HW identifier). You can change the addresses later. The HW identifiers
cannot be changed.
At startup, the system components compare the configured preset configuration with the
actual configuration of the system. By means of parameter assignment, you can specify the
response of the CPU to errors in the hardware configuration.
"Assigning parameters" is understood to mean setting the properties of the components
used (CPU, modules).
STEP 7 compiles the hardware configuration (the result of "configuring" and "assigning
parameters") and downloads it to the CPU. The CPU then connects to the configured
components and transfers their configuration and parameters. Modules can be replaced very
easily because when a new module is inserted, STEP 7 transfers its configuration and
parameters again.
