Simatic S5 Memory Mapping

S5 UniLink Adapter Installation and Operation
A.1 Memory Type Overview
This appendix describes how the TI505 data types map to S5 data types and
vice versa. Each of the eleven S5 data types supported by the CP 525
module is described in detail as seen through the CP module in relation to
each one’s TI500/TI505 counterpart.
Table A-1 represents the equivalent memory types that correspond between
TI500/TI505 PLCs and S5 PLCs. Because of the significant differences in
the internal memory structure and architecture between the two PLCs,
these equivalents represent a subset of the total sets of memory types
available to each.
