B.1 Addressing S5 Modules
There are two ways of using an IP xxx S5 module in the S7-400:
 By installing it in the adapter casing in the S7 central rack
 By using an S5 expansion rack and connecting the S5 module via the
IM 463-2 interface module in the S7 central rack and the IM 314 interface
module in the S5 expansion rack.
In order to be able to address an S5 module in the S7-400, you must set
addresses in two different places:
 The address under which the module is to be referenced in the user
program and the address set on the module must be entered in STEP 7.
 The address of the S5 module in a permissible S5 address space (address
switch on the module).
The address under which the module is to be referenced in the S7-400 must
be set under STEP 7. It is not possible to use default addresses.
Proceed as follows for an S5 module in the S7-400:
– S7 address: Logical address. The value range depends
on the CPU.
– S5 address: Address set on the module. Value range
from 0 to 255.
– Length: Size of the address block. Value range
from 0 to 128 (in bytes).
– Process image
subarea: Process image subarea specification.
Value range: 0 (entire process image)
1 to 8 (process image subarea)
– Area: Value range P, Q, IM3, IM4.
