CP 343-1 Advancedfor Industrial Ethernet / Manual Part B

Release 06/2008

C79000-G8976-C202-04

C−PLUG formatting

Use only C−PLUGs that are formatted for the CP 343−1. C−PLUGs that have

already been used and formatted in other device types must first be formatted for

the CP 343−1 device type.

You do this with STEP 7 / NCM Diagnostics. For more detailed information, refer to

the online help in the topic “General Diagnostics Functions − C-PLUG Diagnostics

Object”.

After formatting, all data areas are deleted on the C-PLUG. Project engineering is

adopted only after reloading or after turning on the power supply again.

Removing the C-PLUG

It is only necessary to remove the C−PLUG if a fault occurs on the basic device

(see Figure 3-2).

Notice

The C−PLUG must be removed only when the power is off!

Diagnostics

Inserting a C−PLUG containing the configuration of an incompatible device type,

accidentally removing the C−PLUG or general malfunctions of a C−PLUG are

signaled by the diagnostic mechanisms of the host device (SF−LED red).

3.3 Module replacement without PG

General procedure

The project engineering data for the CP is stored optionally on the CPU or on the

CP or in the C−PLUG of the CP; this means that the module can be replaced with

the module of the same type (identical order number) without a PG.

If you replace the module with the predecessor module

6GK7 343−1GX21−0XE0, the gigabit interface is deactivated.

For information on replacing previous modules, refer to the section “Compatibility”

in Chapter 8.
