The SIMATIC Automation Compare Tool allows you to compare or view STEP 7 program objects
The following STEP 7 program objects are supported::
- Code blocks
- PLC tag tables
- Data blocks (DBs)
- User data types (UDTs)
The objects must be in SimaticML format. SimaticML is a Siemens proprietary XML format for STEP 7 program objects. You can use tools such as TIA Portal Openness and Version Control Interface (VCI) to save STEP 7 objects to SimaticML files. You can also export a comparison or view to a PDF file.
