I'm doing Hardware configuration on Step 7, S-300, 315-2PN/DP. Insert couple of DI, DO AI and AO module. When I assign them address, I assigned AI1 with 100 to 115, then I tried to give 116 to AI2, but the system doesn't let me, only want me assign 128. I don't have any other module using address from 116 and I checked Address Overview, the 116 to 143 is a gap.
Why is that happening? So wired.
