Stand-alone operation

Overview
This chapter provides you with the necessary information for stand-alone operation of the
CPU 410-5H. 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 to configure stand-alone operation of a CPU 410-5H
● how you can expand a CPU 410-5H to form 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 410-5H in a standard SIMATIC-400 station.
Reasons for stand-alone operation
● No requirements for increased availability
● Use of fault-tolerant connections
● Configuration of the S7-400F fail-safe automation system
Note
The self test is part of the fail-safe concept of the CPU 410-5H and also takes place in
stand-alone operation.
