For S5-115U, -135U and 155U:
You can add an IM308C as a Profibus DP slave device.
But it will be expensive, and I am not even sure if you can get that module any more as it has been put on the phase-out list. It is not in my price-list from Siemens for example.
 
Hello necyil;

Pretty vague question, at this point; it would be helpful to know what S5 fanily these I/O modules belong to (S5-100U, S5-115U, S5-135-U...)and what rack and power supply you have presently for them.

You can notice from the first look that your S5 I/O modules do not fit in the S7-300 rack (rail + bus connector system). You have to look into a remote I/O configuration (Profibus-DP).

Supposing you have an expansion rack and power supply for the S5 I/O modules, you could probably use a IM308-C as a Profibus-DP slave in that rack, and configure the I/O points over Profibus.

Come back with more information, we'll try to give you more precise answers.

Hope this helps,
Daniel Chartier
