Configuring - Siemens SIMATIC S7-1500 Automation System System Manual

Configuring

In order that the S7-1500 automation system knows how it is to be configured (preset
configuration) and how it is to operate, you must configure the individual hardware
components, assign parameters to them, and connect them to each other. The work needed
for this is undertaken in the device and network view in STEP 7.
Configuring" is understood to mean arranging, setting and networking devices and modules
within the device or network view. Modules and module carriers are graphically represented.
Just like "real" module carriers, the device view allows the insertion of a defined number of
modules.
When the modules are plugged, STEP 7 automatically assigns the addresses and a unique
hardware identifier. The addresses can be changed subsequently. However, the hardware
identifiers cannot be changed.
When the automation system is started, the CPU compares the configured planned
configuration with the system's actual configuration. You can carry out parameter
assignment of the response of the CPU to errors in the hardware configuration.
"Parameter assignment" is understood to mean setting the properties of the components
used. The hardware parameters and the settings for data exchange are thereby assigned:
● Properties of the modules to which parameters can be assigned
● Settings for data exchange between components
The parameters are loaded into the CPU and transferred to the corresponding modules
when the CPU starts up. Modules can be replaced with ease since the parameters set are
automatically loaded into the new module during startup.
