Which Block Version Should I Use?

The following descriptions also include information on differences between the

various block versions. Please take note of the version identifiers of the blocks you

are using.

The SIMATIC Manager block libraries installed with STEP7 / NCM S7 contain the

block versions that were current at the time of the STEP 7 release.

Note

We recommend that you always use the latest block versions for all module types.

You will find information on the current block versions and the current blocks to

download from the Internet in our customer support.

Entry ID: 8797900

With the older module types, this recommendation assumes that you are using the

latest firmware for the particular block type.

Notice

At various points in this chapter, you will find information on the different CP

versions. These passages are highlighted with the following symbol:

Newer CP types are CPs / module types with the following versions or higher:

CP 343-1

6GK 7343-1EX11-0XE0 version 1 or higher / firmware version V2.0 or higher

CP 343-1PN

6GK 7343-1HX00-0XE0 version 1 or higher / firmware version V1.0 or higher

CP 343-1 IT

6GK 7343-1GX11-0XE0 version 1 or higher / firmware version V2.0 or higher

FCs and Module Replacement (Spares)

Module replacement in this sense means the replacement of a module with

another module that may be a more recent version.
