Define Profinet Variables

Creates your own Profinet Variables in RobFlow and exports them so the PLC side can be generated from the same definition.

Steps

1. In RobFlow, define the Variables you need. The supported types and their lengths are listed under Profinet Variables. The byte offset is calculated automatically and can be seen in RobFlow for reference.
2. Export the .udt file from the RobFlow Variable Inspector and download the file to a storage medium.

The .udt file contains a struct definition holding the defined Variables in the correct order and of the correct type.

note

You can not exceed a total length of 256 bytes.

Next

Bring the exported file into TIA Portal — Update Profinet Variables.
