5.2 Configuring the CPU
CPU 1516pro-2 PN (6ES7516-2PN00-0AB0)
38 Operating Instructions, 11/2019, A5E35873416-AC
Result of the hardware detection
STEP 7 has read out the hardware configuration including the modules and transferred them
to your project. STEP 7 assigns a valid default parameter assignments for all modules. You
can change the parameter assignment subsequently.

Note
If you want to go online after the hardware detection, you have to first download the detected
configuration to the CPU; otherwise, an error may occur due to inconsistent configurations.
Properties of the CPU
The properties of the CPU have special significance for system behavior. For the CPU, for
example, you can make the following settings in STEP 7:
● Startup characteristics
● Parameter assignment of the interfaces, for example, IP address, subnet mask
● Web server, e.g., activation, user administration, and languages
● OPC UA server
● OPC UA client
● 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.
