Simatic S5 Memory Mapping

S5 UniLink Adapter Installation and Operation
A.10 S5 Data Types Not Supported by S5 PIM
Due to significant differences in the internal memory structure and
architecture between the TI500/TI505 PLCs and the S5 PLCs, no
compatible memory translations to these specific S5 data types are
available.
The S5 Analog I/O Bytes memory type as accessed through a CP module is
not supported by the S5 PIM.
Access to Analog I/O will be through Data Block memory, which implies that
all analog conversions will be taken care of in the STEP 5 program. This
was determined because of the significant differences in the internal
memory representation of analog I/O.
The S5 Extended Analog I/O Bytes memory type as accessed through a CP
module is not supported by the S5 PIM.
Access to Extended Analog I/O will be through Data Block memory, which
implies that all analog conversions will be taken care of in the STEP 5
program. This was determined because of the significant differences in the
internal memory representation of analog I/O.
The S5 Absolute Address memory type as accessed through a CP module is
not supported by the S5 PIM.
The S5 System Address memory type as accessed through a CP module is
not supported by the S5 PIM.
