electronics can be anyway remotely controlled by single boards which are inserted in the
SY 1527 mainframe and act as branch controllers.
Fast, accurate set-up and monitoring of system parameters (14-bit resolution on Voltages
and Currents with standard boards) is available for each branch controller thanks to the
use of one microprocessor per slot. All the operational parameters are stored in a non-
volatile memory (EEPROM) to be still available after Power-Off. The parameters can be
controlled either via CAEN traditional built-in links (RS232, H.S. CAENET) or via CERN-
approved Fieldbuses or via Ethernet (TCP/IP). Programmable handling of parameters
and errors is available as well.
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 global down time, and
easy access to the computing core and peripherals completes the system’s flexibility.
Easy interfacing is another key-point of the SY 1527 system. Thanks to the H.S.
CAENET interface, the system ensures full communication compatibility with the
previous models. Besides the RS232 interface and Ethernet (TCP/IP) provided with the
standard version of the system, CAN-bus can be furnished on request, as well as special
boards featuring optical links for remote communications. The Power Supply Section and
Board Section can be externally synchronised via front panel connectors.
Secure access to the system via Intranet is foreseen together with a multilevel
management of custom User's 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, Telnet and WWW access facilities allow remote debugging
and technical support of the system, including future firmware upgrading.
