Memory addresses
Memory addresses are converted as defined in the following table. S7-200 I/O address
ranges are fixed by the CPU operating system. However, you can modify S7-1200 I/O
address ranges during CPU device configuration.
Therefore, the S7-1200 I/O addresses shown in the following table are example addresses
only.

STEP 7-Micro/WIN System block parameters are not converted. You must use STEP 7
Basic Device configuration to set up PLC system options.
Program code blocks created by STEP 7-Micro/WIN wizards are not converted.
STEP 7-Micro/WIN can use Siemens supplied libraries (USS protocol and Modbus
protocol) and user-defined libraries. Siemens supplied libraries are provided in STEP 7-
Micro/WIN *.mwl file form and are not converted. User-defined library *.mwl files are
created from user-created source program *.mwp files. The *.mwp library source
programs can be converted to STEP 7 Basic programs and assigned as a global or
project library with the STEP 7 Basic library functions.
STEP 7-Micro/WIN Status charts are not converted. You must create a STEP 7 Basic
watch table to monitor the run-time values of program variables.
