A system of many thousands of DC isolated power supplies for ATLAS Semi-Conductor Tracker (SCT) controlled by about 14 000 microprocessors forms a large system which temporal properties are essential for reliability.This system passes now various integration tests.Highlights of the system architecture are presented and details of communication aspects for the high voltage (HV) subsystem are described.I.
