TIA Portal Exporter Utility

The TIA Portal Exporter Utility enables export of the specific tags users need from Siemens S7-300, S7-400, S7-1200 or S7-1500 controllers programmed with Siemens TIA Portal for automatic generation in their TOP Server project. Provided as a standalone installation, it is compatible with TIA Portal V13 SP1, V13 SP2, V14, V14 SP1, V15, V16, V17, and V18

Capabilities include:

  • Select a specific controller within the Siemens TIA Portal project
  • Select tags from all tag tables, data blocks, UDTs and function blocks
    Search/filter on tag name, address or data type
  • Import the specific tags required in a TOP Server project

Download the TIA Portal Exporter Utility (also installed with TOP Server)
