Is it possible to connect S800I/O with S7-400?
I would like to know if there is any communication interface (CI) that connects S800I/O with a Siemens PLC S7-400? Or is there another way to make this communication happen?
Thanks in advance

This should be with using of CI801 or CI830 (with GSD file/s) for S800IO and connect them as slave to S7-400.
