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
Definition
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
Note
The self-test is an integral component of the F-concept of the CPU 410 and is also
performed in stand-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".
