Stand-alone operation
Overview
This chapter provides you with the necessary information 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 to configure stand-alone operation of a CPU 410
● how you can expand a CPU 410 to form a fault-tolerant system
● which system modifications are possible during stand-alone operation and which
hardware requirements must be met
Definition
By stand-alone operation, we mean 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 connections
● Configuration of the S7-400F fail-safe automation system
A fail-safe user program can only be compiled for execution on the CPU 410 with a F-
runtime license (for more details refer to Manual
S7-400F and S7-400FH Automation
Systems
).
Note
The self
-test of the CPU 410 is also performed in stand-alone operation.
