Option

Meaning / Effect

 

 

S Replace Module without PG

With this option, you can have the configuration data of the CP stored

 

on the CPU. If you then replace CP, the configuration data for the

 

new CP are downloaded automatically from the CPU when the CP is

 

started up.

 

If you select this option, the configuration data are stored long-term

 

on the CPU instead of in the EEPROM of the CP. Remember,

 

however, that long-term storage on the CPU is only safe from power

 

outages if the CPU is protected by battery backup or by using an S7

 

Memory Card.

 

Note

 

If you store the configuration data on the CPU, please read the note

 

below.

 

The following functions do not modify the configuration data on the

 

CPU:

 

S Resetting module memory

 

S Resetting to factory settings

 

S Assigning an IP address1) (using the target system selection in

 

the SIMATIC Manager or the properties dialog in HW Config or

 

NetPro)

 

If you subsequently upload the configuration data from the CPU to a

 

PG you will always object the configuration data that were previously

 

on the CP (with parameters, connections, IP address).

 

1) Note: You should only use the assign IP address function during

 

commissioning; in other words, before downloading the configuration

 

data.

 

 

S Ethernet Profile for

Select this profile if you use fault-tolerant communication in your

Fault-Tolerant Connections

system. Fault-tolerant communication means that Industrial Ethernet

 

is designed with redundancy and that you have configured

 

fault-tolerant S7 connections.

 

If you select the Ethernet profile for fault-tolerant connections here,

 

the time response of the S7 connections is adapted. As a result,

 

breakdowns of a connection are detected more quickly and the

 

failover to redundant connections is faster.

 

 

 

Note

 

Select the Ethernet profile for fault-tolerant connections only when

 

you actually use fault-tolerant S7 connections. Otherwise you must

 

expect your system to be more susceptible to problems since, for

 

example, the number of transfer or connection establishment

 

attempts is reduced compared with non-redundant systems.
