3.2 C-PLUG (configuration plug)

Exchangeable C−PLUG

The CP has a receptacle for configuration plug (known as a C−PLUG) that is

supplied as standard with the device. This can store up to 32 MB of data in

nonvolatile memory.

Area of application

The C−PLUG is an exchangeable medium for storing configuration and project

engineering data of the basic device (CP 343−1). This means that configuration

data remains available if the basic device is replaced. It is possible to replace the

module without a PG.

The retentively stored parameters include the complete configuration data:

S IP address and IP parameters

S A newly set MAC address

S LAN settings

S SNMP Variables (modifiable)

S Interconnection information for PROFINET CBA

Notice

The CP functions are available only when a C−PLUG is inserted.

If the C−PLUG is missing, the CP starts up but only diagnostic functions are

available.

Recommendations for data storage

We always recommend that you store the project engineering data on the CPU.

If the configuration data is extensive, for example due to maximum PROFINET IO

configurations, it is advisable to store the configuration data on the CP (on the

C−PLUG) in the following situations:

S The configuration memory on the CPU is inadequate;

S The delays due to the extent of the configuration data when starting up the

module are unacceptable.
