S7 TIA PROFINET driver

Observe these guidelines when working with the S7 TIA PROFINET driver.

Supported controllers

The driver supports these controller families:
  • Siemens® S7-1200 Series
  • Siemens® S7-1500 Series

Controller tags import

The driver supports only optimized structures.
You can import tags in these modes:
Online mode
Use online mode to import tags directly from the controller at design time or runtime.
IMPORTANT:
Before importing tags from a controller:
  • Set
    Access level
     to a
    Full access
     option.
  • If applicable, disable the
    Only allow secure PG/PC and HMI communication
     option.
For more information, refer to the product documentation.
Offline mode
Use offline mode to import tags from these project files:
ap13
,
ap14
,
ap15
,
ap16
,
ap17
,
ap18
,
ap19
.
IMPORTANT:
Before importing tags from a project file:
  • Ensure that the project file is compiled with the
    Optimized block access
     property enabled.
  • If your project has multiple programs, choose the program from which you want to import the tags.
  • If the controller communication is authenticated with certificates:
    • From TIA Portal®, export the
      DER
       certificate and then paste the certificate into the
      FTOptixApplication/ProjectFiles/PKI/Own/Certs/
       folder of the
      FactoryTalk Optix
       project.
    • In
      FactoryTalk Optix Studio
      , in the
      Controller certificate file
       property of the
      S7TIAPROFINETStation
      #
       object, select the exported certificate.
For more information, refer to the product documentation.
