What you have to take into account for stand-alone operation of a CPU 410  
 
-alone operation of a CPU 410, no synchronization modules may be connected. The 
rack number must be set to "0".
 
The table below lists the differences between the operation of a CPU 410 in stand-alone 
mode and redundant mode.  
Table B-1 Differences between stand-alone and redundant operation 
 
CPU 410 in stand-alone operation 
CPU 410 in redundant system state 
System modifications during 
operation 
Yes, as described in Manual "Modifying 
the System during Operation via CIR". 
Yes, as described in Chapter Failure and 
replacement of components during 
redundant operation (Page 167) for 
Fault tolerance-specific LEDs 
The REDF, IFM1F, IFM2F, MSTR, RACK0 and RACK1 LEDs show the reaction specified in 
the table below in stand-alone operation.

Configuring stand-alone operation  
Requirement: No synchronization module may be inserted in the CPU 410. 
Procedure: 
1.  Insert a 
 station in your project. 
2.  Configure the station with the CPU 410 according to your hardware configuration. For 
stand-alone operation, insert the CPU 410 in a standard rack (Insert > Station > S7-400 
station in SIMATIC Manager). 
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".
