PART_TRACK_RFID
RFID / 2D-code part identity at a station: bounded read attempts, a held tag tied to the carrier present, and an explicit unidentified state.
When to use it
Use PART_TRACK_RFID when parts or carriers are identified at each station by an RFID tag or a code reader, and the station's decisions — recipe, torque program, pass/fail attribution — depend on knowing which part it is holding.

Create a free Ri Tech account to download the block. You get the Structured Text body, the Rockwell Add-On Instruction (.L5X), the Schneider Control Expert DFB (.XDB), PLCopen XML, the IEC 61499 function block type (.fbt) and the datasheet.
Every block in the catalogue is free to download, in every format, with no purchase and no card. Browsing needs no account at all; downloading needs a signed-in one, so the block lands in your library and re-downloads whenever you need it.
Source is never published on this page. The implementation is released to a signed-in Ri Tech account — free of charge, but never anonymously.
