B7100006 — Error in MUDAT — generic gantry optical data-transfer fault

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

What B7100006 means

On Aquilion RX and Aquilion ONE and Aquilion S16 and Aquilion 16 and Asteion Super4 CT systems, status code B7100006 indicates: Error in MUDAT — generic gantry optical 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: Because the message names no sub-code, start broad and narrow with the six error-identification tools: DAS test and Console test to establish whether the data source or the console side is healthy, then ROTSOT and SOTROT tests for each direction of the link, then OPCONTA test and GCIFA test for the boards. Read the GCIFA and OPCONTA fault LEDs against the manual's data-transfer error table — the LEDs usually name the specific error type the console message omits..

Toshiba / Canon Medical CT systems using the MUDAT optical link (Aquilion RX, Aquilion ONE, Aquilion S16, Aquilion 16 and Asteion Super4). The console message carries no sub-code, so it identifies only the unit: MUDAT, the optical data-transmission unit in the gantry, with the OPCONTA PWB as the rotation-section interface and the GCIFA PWB as the stationary-section interface.
