B7100007 — Error in MUDAT (ROTSOT -7) — rotation-to-stationary transfer error

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

What B7100007 means

On Aquilion RX and Aquilion ONE and Aquilion S16 and Aquilion 16 and Asteion Super4 CT systems, status code B7100007 indicates: Error in MUDAT (ROTSOT -7) — 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: If the fault is intermittent, capture it rather than chase it: note the GCIFA and OPCONTA fault LEDs immediately after it appears and match them to the data-transfer error table, since several ROTSOT types latch only after repeated errors. Then run the ROTSOT test, followed by the OPCONTA test and GCIFA test to separate a marginal board from a marginal optical path. Clear from the console, or allow 2 s of normal transfer to auto-correct, before re-testing..

Toshiba / Canon Medical CT systems using the MUDAT optical link (Aquilion RX, Aquilion ONE, Aquilion S16, Aquilion 16 and Asteion Super4). ROTSOT faults are detected by the GCIFA on the stationary side and reported to the system through the KGTSM; several ROTSOT error types are raised only after a transfer error repeats in succession, so an intermittent link can produce them sporadically.
