S5 And Profibus

Hi all!

I´ve got a custumer that have a machine, its controlled by a S5 (115U), the system have several Distributed I/Os. And there is some kind of buss between them (dont know witch, havnt seen this machine myself). Now he wont to replace the CPU with a S7 (300) but keep the S5 I/O cards. Is there any card that I place in the distributed I/O racks so I can communicate over Profibus to them (like a IM 153-1 card for s7)?

Best Regards!

Hi

You can use a 318 module in the extension rack

see link for more info it for a 155U but should be working on a 115U

Here are my thoughts on the subject:

My best advice is to bite the bullet and exchange everything S5 for something newer. Do not keep any of the old S5 hardware.
