Configuring ET 200SP

Introduction
The ET 200SP distributed I/O system is configured and assigned parameters with STEP 7
(CPU/interface module, I/O modules, motor starter and server module) or using configuration
software of a third-party manufacturer (interface module, I/O modules, motor starter and
server module).
"Configuring" is understood to mean the arranging, setup and networking of devices and
modules within the device view or network view. 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 hardware
identifiers cannot be changed.
When the automation system is started, the CPU/interface module compares the configured
planned configuration with the system's actual configuration. You can make parameter
settings to control the response of the CPU/interface module to errors in the hardware
configuration.
"Parameterizing" the components used signifies setting their properties. During parameter
assignment, the hardware parameters are set and the settings for data exchange are made:
● Properties of the modules to which parameters can be assigned
● Settings for data exchange between components
STEP 7 compiles the hardware configuration (result of "configuring" and "assigning
parameters") and downloads it to the CPU/interface module. The CPU/interface module then
connects to the configured components and transfers their configuration and parameters.
Modules can be replaced very easily because STEP 7 transfers the configuration and
parameters when a new module is inserted.
