S7 TIA PROFINET driver
Observe these guidelines when working with the S7 TIA PROFINET driver.
Supported controllers
S7 TIA PROFINET driver supports these controller families:
- Siemens® S7-1200 Series
- Siemens® S7-1500 Series
Controller tags import
With the S7 TIA PROFINET driver, you can import tags in these modes:
- Online mode
- Use the online mode to import tags directly from the controller at design time or runtime.IMPORTANT:Before importing tags from a controller:
- SetAccess levelto aFull accessoption.
- If applicable, disable theOnly allow secure PG/PC and HMI communicationoption.
For more information, refer to the product documentation. - Offline mode
- Use the offline mode to import tags from these project files:ap13,ap14,ap15,ap16,ap17,ap18.IMPORTANT:Before importing tags from a project file:
- Ensure that the project file is compiled with theOptimized block accessproperty enabled.
- If your project has multiple programs, choose the program from which you want to import the tags.
For more information, refer to the product documentation.
