B7100005 — Error in MUDAT (ROTSOT -5) — rotation-to-stationary transfer error

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

What B7100005 means

On Aquilion RX and Aquilion ONE and Aquilion S16 and Aquilion 16 and Asteion Super4 CT systems, status code B7100005 indicates: Error in MUDAT (ROTSOT -5) — 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, which is the tool that specifically covers the OPCONTA, LPBA (ROT), SPDA and GCIFA chain, and note where it reports the failure. If the optical elements are implicated, inspect the emitter and photodiode units for contamination or misalignment before replacing a board. Read the GCIFA and OPCONTA fault LEDs against the data-transfer error table, and clear the latched error from the console before you re-test..

Toshiba / Canon Medical CT systems using the MUDAT optical link (Aquilion RX, Aquilion ONE, Aquilion S16, Aquilion 16 and Asteion Super4). ROTSOT is transmission from the rotation section to the stationary section, checked at the GCIFA; the beam path on that direction runs from the LPBA (ROT) emitter PWB on the rotation section to the SPDA photodiode PWB on the stationary section.
