I don't believe the you can put a SLC processor on PROFIBUS. You need a specialty I/O module made by SST. The P/N is SST-PFB-SLC. You configure the M0 and M1 files in RSLogix500 per the manual, then configure the modules PROFIBUS setiings (address, baud, etc.) thru the top com port of the module, using Hyper-Terminal and a null-modem cable.
