Test sequences
Hoist interlocks, trolley/bridge limits, brake timing, overload trip, e-stop chain, anti-sway
Typical workflow
- Connect the laptop to service port 12; confirm a 192.168.99.x address.
- Open ATT → New test run → select the crane unit from Masterdata (unit ID on the e-house door).
- Run the sequence pack for the crane type. Failed steps are re-runnable individually.
- Sign & export — the report is uploaded to Masterdata automatically when online, otherwise saved locally and synced later.
ATT only reads PLC values and triggers test functions through the PLC test interface. It never writes production parameters.
