Siemens Data transfer between PLCs

[rageshn]

Hello Friends, I have an application where we have 2 ET200 Pro PLCs and we need to send about 2000 Bytes of data between them . The 2 PLCs are connected to each other using a Plant Network and we have also the ability to connect them using ethernet cable also using scalance switch. Any help on what FC/FB to use , any sample reference , any help will be greatly appreciated. Thanks, Ragesh
