Alarm — high severityMUDAT (data transfer system)

B7100000 — The data transfer system in the gantry is abnormal (MUDAT)

Canon Medical (Toshiba) CT error code, reported by the MUDAT (Multi-Data Transmitting System) — optical data-transfer link.

What B7100000 means

On Aquilion RX / V4-62R004 and V3.20R003 and Aquilion ONE / V4.2 CT systems, status code B7100000 indicates: The data transfer system in the gantry is abnormal (MUDAT). The code originates in the MUDAT (data transfer system) section of the MUDAT (Multi-Data Transmitting System) — optical data-transfer link. Severity level A1 (Alarm — high severity).

Reported action: Stop scanning and note the exact conditions — scan type and gantry state — when the fault appeared. Isolation is service-level work and the manual gives dedicated tests for the data-transfer section: the DAS test and the console test place the fault inside or outside MUDAT, the ROTSOT and SOTROT tests show which transfer direction fails, and the OPCONTA and GCIFA tests point at the interface board itself, read alongside the fault LEDs on the GCIFA and OPCONTA PWBs..

Reported on Aquilion RX/V4-62R004, Aquilion ONE/V4.2 and V3.20R003 — this code is not present in the Aquilion 16 / Asteion Super4 tables. It comes from the 9:Device MUDAT table, where the OEM text reads "The data transfer system in the gantry is abnormal." MUDAT is the service manual's name for the optical data-transmission unit in the gantry, which moves data between the rotation section and the stationary section; the console reports a general failure of that transfer system rather than naming one board.
