B7110001 — An error has occurred in data transfer system (2) during scanning

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

What B7110001 means

On Aquilion RX and Aquilion ONE CT systems, status code B7110001 indicates: An error has occurred in data transfer system (2) during scanning. 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: Since the fault appears under acquisition load, reproduce it with a scan rather than at rest: read the GCIFA and OPCONTA fault LEDs right after it occurs and match them to the manual's data-transfer error table, then run the ROTSOT and SOTROT tests to establish which direction of the link fails and the OPCONTA and GCIFA tests to isolate the board. Check the optical path and the power feeding both interface boards before replacing anything..

Toshiba / Canon Medical Aquilion RX and Aquilion ONE CT systems, on the gantry data-transfer path. The console raises this one while a scan is in progress, so it points at the MUDAT link under acquisition load rather than at an idle-state fault.
