Table 10-1 shows which address areas can be used in the S5-95U for
distributed I/O, how access is implemented in the STEP 5 application
program and how many inputs/outputs are available.

Caution
Danger of double address assignments.
Input/output bytes 64 to 127 are used by the local I/O (e.g. analog
input/output modules, slots 0 to 7) as well as the distributed I/O (DP slaves).
If you use local I/O (e.g. analog input/output modules), you must reserve the
address areas with COM ET 200 Windows in the host parameters (see Table
8-4, Section 8.2.2).
If you use the S5-95U as DP master, linear addressing is the only option. You
must assign one and only one address to each input/output of a DP slave.
"Linear" is predefined as a master parameter in COM ET 200 Windows. This
mode applies to all DP slaves assigned to the DP master.
