Extention rack (for example from S7-200) is just to split a original rack in two narrow lines.

One thing i would like to add here is that u must also keep power usage of cards in consideration if u are going to use 32 cards as u are then required to place Power Module in between card

This greatly increased the amount of I/O readily available. You just need another S7-1200 for each additional set of expansion modules. Of course, you can use ET200's for distributed/remote I/O to increase further.

Hi,

in general this can be found in technical data of your cpu..

For example:

6ES7214-1AF40-0XB0

"

Number of modules per system, max.

3 comm. modules, 1 signal board, 8 signal modules

"

hope this helps

regards

sancruz
