A 70 GeV Proton Synchrotron Extracted Beam Lines Control System is described. About 130 Magnet Dipoles and Quadrupoles, 20 Correction Magnets, 50 Beam Collimators, BPM equipment spread over 1 km have to be controlled.The old System was based on the PDP11/40 and LSI-11 compatible computers and the MIL 1553 STD as a Field BUS. It successfully operated about 15 years.A new system includes home made Equipment Controllers based on the I 8051 Processor connected by CAN Field Bus to FECs. FECs, Servers, Consoles are connected by Ethernet. On the first stage of modernization PDPs and LSIs are replaced by PCs connected by Ethernet. Equipment Controllers are being successfully tested in the Collimators and Corrector Magnets Controls during a run.
