Stand-alone operation
Overview
This section provides information needed for stand-alone operation of the CPU 410. You will
learn:
● how stand-alone operation is defined
● when stand-alone operation is required
● what you have to take into account for stand-alone operation
● how the fault tolerance-specific LEDs react in stand-alone operation
● how you configure a CPU 410 for stand-alone operation
● how you can expand a CPU 410 into a fault-tolerant system
● which system modifications are possible during stand-alone operation and which
hardware requirements must be met
Stand-alone operation is the use of a CPU 410 in a standard SIMATIC-400 station.
Reasons for stand-alone operation
● No requirements for increased availability
● Use of fault-tolerant communication connections
● Configuration of the S7-400F fail-safe automation system
-test is an integral component of the F-concept of the CPU 410 and is also
-alone operation.
What you must observe for stand-alone operation of a CPU 410
Observe the following for stand-alone operation of a CPU 410:
● No synchronization modules are permitted to be inserted in stand-alone operation of a
CPU 410.
● The rack number must be set to "0".
