B7100001 — Error in MUDAT (ROTSOT -1) — rotation-to-stationary transfer error

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

What B7100001 means

On Aquilion RX / V4-62R004 and V3.20R003 and Aquilion ONE / V4.2 and Aquilion S16 and Asteion Super4 and Aquilion 16 CT systems, status code B7100001 indicates: Error in MUDAT (ROTSOT -1) — rotation-to-stationary transfer error. 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: Run the ROTSOT test first: it drives test data from the rotation side across to the GCIFA, so a failure confirms the rotation-to-stationary path rather than the console. If it passes, the OPCONTA test and the GCIFA test loop test data back within each board and point at the faulty one. Read the GCIFA and OPCONTA fault LEDs against the manual's data-transfer error table while you do it..

Reported on Aquilion 16, Aquilion RX/V4-62R004, Aquilion ONE/V4.2, Aquilion S16, Asteion Super4 and V3.20R003. It comes from the 9:Device MUDAT table, where the OEM text reads "Error in MUDAT (ROTSOT -1)." ROTSOT is the manual's term for transmission from the rotation section to the stationary section. In the manual's data-transfer error table, ROTSOT error type <1> is an error that occurred while control data was transferred from the rotation section to the stationary section (judged by check bit), with no system error handling listed and GCIFA LED14 as its display LED.
