Alarm — high severityMUDAT (data transfer system)

B710000A — Error in MUDAT (10) — indexed gantry data-transfer fault

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

What B710000A means

On Aquilion RX and Aquilion ONE and Aquilion S16 and Aquilion 16 and Asteion Super4 CT systems, status code B710000A indicates: Error in MUDAT (10) — 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: The message gives you an index, not a diagnosis, so go to the hardware for the name: read the fault LEDs on the GCIFA and the OPCONTA and identify the error type in the manual's data-transfer error table, which lists 25 detected error types with their display LED. Then confirm the direction with the ROTSOT and SOTROT tests and the boards with the OPCONTA and GCIFA tests..

Toshiba / Canon Medical CT systems using the MUDAT optical link (Aquilion RX, Aquilion ONE, Aquilion S16, Aquilion 16 and Asteion Super4). The console message reports only a numeric index rather than an error name, so the identification has to come from the gantry-side fault LEDs and the built-in tests rather than from the message text.
