The Microsoft .NET API used by the SIMATIC Automation Tool is documented in this user
guide. You can create your own application software that uses the API to perform the same
device operations as the SIMATIC Automation Tool.
The SIMATIC Automation Tool must be installed on any PG/PC that uses this API. The
SIMATIC Automation Tool and your application software use the API .dll file and additional
S7 communication files. The SIMATIC Automation Tool installation provides all the files that
you need.

written against this API must be refactored. For details of the V2.1 API, refer to the SIMATIC
