Configure the S7-1200 CPU and I/O modules

Note

The converter tool does not configure the S7-1200 CPU and I/O modules.

Do not rename any tags until after you get the project to compile without errors. Otherwise, the changes will only take effect in the blocks that are opened in the program editor. For example, you want to change the tag "SM0_0" that the converter created to "Always_On". When the project compiles without errors, the system automatically updates the modified tag names in all the blocks for you.

● Use the STEP 7 Basic Device configuration to either detect the configuration of the connected S7-1200 system or specify the system components from the Hardware

catalog. All S7-200 programs are initially converted to the unspecified S7-1200 CPU type. ● S7-200 system Block CPU parameters and CPU status and control functions that are programmed by SM memory addresses are not converted. You must set up the corresponding S7-1200 CPU properties using STEP 7 Basic Device configuration

settings. CPU options that your S7-1200 program will use must be properly configured, before your program can access or operate those CPU options. ● It is also helpful to enable the System and Clock memory bits to replace the commonly used SMB0 bits in your project. Use an M byte above MB32 so as to not conflict with the M memory usage in the S7-200 project. ● If you are an OEM, then change the Startup mode from "Warm restart – Operating mode before POWER OFF" to "Warm restart – RUN". Otherwise, if the CPU goes to stop because of a program update from a memory cartridge or an error, you will have to provide software to put the CPU back into Run mode.

2.6 Compare the program blocks in the original program and the converted program 2.6Compare the program blocks in the original program and the

converted program

The purpose of the comparison is to identify the subroutines, interrupt routines, and data

block data that were converted.

●Open the original program in STEP 7-Micro/WIN and open the converted program in

STEP 7 Basic, at the same time. Compare the POU (Program Organizational Unit) block

structure of original S7-200 program with the converted STEP 7 Basic program.

●Use the STEP 7-Micro/WIN Instruction tree and open the "Program Block" and "Data

Block" branches.

●Use the STEP 7 Basic Project tree and open the "Project blocks" branch.

The subroutines, interrupt routines, and V memory data groups (data block tabs) created by

STEP 7-Micro/WIN wizards and library usage are protected and are not converted. Also

user-protected POUs or V memory tabs are not converted.
