Alarm — high severityMUDAT (data transfer system)

B710000C — Error in MUDAT (12) — indexed gantry data-transfer fault

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

What B710000C means

On Aquilion RX and Aquilion ONE and Aquilion S16 and Aquilion 16 and Asteion Super4 CT systems, status code B710000C indicates: Error in MUDAT (12) — indexed gantry data-transfer fault. 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: Capture the gantry-side state before clearing anything: read the fault LEDs on the GCIFA (bottom rear of the gantry) and on the OPCONTA (rotation-section chassis), then map them to the error table to get the real error type, its handling and its clearing method. Follow with the ROTSOT/SOTROT tests for direction and the OPCONTA/GCIFA tests for the boards..

Toshiba / Canon Medical CT systems using the MUDAT optical link (Aquilion RX, Aquilion ONE, Aquilion S16, Aquilion 16 and Asteion Super4). Like the other indexed MUDAT messages, this one names the unit and an index only; the physical detail sits in the GCIFA and OPCONTA LED displays and in the manual's data-transfer error table.
