Hello guys,I am communicating a S7-300 PLC as a master with one S5 115U(IM 308C) as slave using Profibus DP.I would like to be able to read all four analog inputs cards (16 inputs each) at the central rack and other four cards at the expansion rack in the S5 PLC from the master S7. So far I have had success reading only three AI cards.Is there some body out there that could help me on this?.

Thanks a lot

Eduardo
