Programming FCs (Functions) and FBs for S7 Ethernet CPs

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 / CP 343-1 EX20

6GK 343-1EX11-0XE0 version 1 or higher / firmware version V2.0 or higher 6GK 343-1EX20-0XE0 version 1 or higher / firmware version V1.0 or higher

CP 343-1PN

6GK 343-1HX00-0XE0 version 1 or higher / firmware version V1.0 or higher

CP 343-1 IT / CP 343-1 IT GX20

6GK 343-1GX11-0XE0 version 1 or higher / firmware version V2.0 or higher 6GK 343-1GX20-0XE0 version 1 or higher / firmware version V1.0 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.

Notice

Please remember that if you replace a module, you must only use the blocks per- mitted for the configured CP type in the user program.

This means:

SIf you replace the module without adapting the configuration data to the possibly newer module type, you do not need to make any changes to the blocks used.

SIf you replace the module and you do adapt the configuration data to the newer module type, you must use the block versions approved for this module type.

We recommend that you always use the latest block versions for all module types. With the older module types, this recommendation assumes that you are using the latest firmware for the particular block type.

You will find more information on replacing blocks in our Customer Support on the Internet.

The manuals /1/ contain information on the compatibility of the S7-CPs and the corresponding blocks (FCs / FBs).
