Power Supply Unit and one board. The system allows also to deal with power supply
solutions composed by “branch controllers” (housed in the system main frame) and on-
detector “remote boards” (manufactured in order to be magnetic field and radiation
tolerant). Channel trip control on other crates is performed via four external differential trip
lines. A sophisticated trip handling via software allows to control and correlate trip
conditions on the channels of the crate as well as of other crates connected to it. Live
insertion and extraction of the boards, which reduces the down time of the global system,
and easy access to the computing core and peripherals of the system complete the
system flexibility. Easy interfacing is another key-point of the SY1527 system, which can
be connected to SY127 and SY527 systems. The Ethernet interface (TCP/IP) allows both
an easy Telnet access and the connection via OPC Server to a SCADA control system.
Enhanced software programming features a unified command set independent from the
interface used to communicate with the system. The Power Supply Section and Board
Section can be externally synchronised via front panel connectors. Multi-layered access
to the system via Intranet is foreseen through the management of several custom user
profiles. In particular, three different access levels have been implemented: Guest, User
and Administrator, each of which with password protection. Handy maintenance and
upgrading, which constitute a major issue in the reliability of a system, are further
guaranteed by the possibility of accessing and servicing the system via network facilities.
Actually, the Telnet access facility allows remote debugging and technical support of the
system, including future firmware upgrading. For a detailed description of the SY 1527
Universal Multichannel Power Supply System please refer to the
SY 1527 User's Manual.
