Configuration
Introduction
In the network view of STEP 7, select the CPU from the hardware catalog and place it,
together with a rack (mounting rail), in the view. Drag the desired I/O modules from the
hardware catalog onto this device; they are arranged automatically on the rack.
If a CPU was already configured and you want to load the current configuration and
parameters in a new project, it is advisable to use the "Upload device as new station"
function. For additional information about this function, refer to section Backing up and
restoring the CPU configuration (Page 84).
Properties of central modules
The properties of the CPU have special significance for system behavior. For a CPU, you
can, for example, make the following settings in STEP 7:
● Startup characteristics
● Parameter assignment of the interface(s), e.g. IP address, subnet mask
● Web server, e.g., activation, user administration, and languages
● OPC UA server
● Global Security Certificate Manager
● Cycle times, e.g., maximum cycle time
● System and clock memory
● Protection level for access protection with assigned password parameter
● Time and day settings (daylight saving/standard)
The properties that can be set and the corresponding value ranges are specified by STEP 7.
Fields that cannot be edited are grayed out.
