Configuring stand-alone operation
Requirement: No synchronization module is permitted to be inserted in the CPU 410.
Procedure:
1.
Insert the CPU 410 in a standard rack (Insert > Station > SIMATIC 400 Station in
SIMATIC Manager).
2.
Configure the station with the CPU 410 corresponding to your hardware configuration.
3.
Assign the parameters of the CPU 410. Use the default values, or customize the
necessary parameters.
4.
Configure the necessary networks and connections. For stand-alone operation, you can
also configure "fault-tolerant S7 connections".
For help on procedure refer to the Help topics in SIMATIC Manager.
Expanding the configuration to a fault-tolerant system
Note
You can only expand your system to a fault-tolerant system if you have not assigned any
odd numbers to expansion units in stand-alone operation.
