SVXII/ISL Power Supply Control, Interlock and Monitoring System
Overview
The SVX-II and ISL power supply control is
based on C routines compiled on a MVME162 CPU module running under VxWorks.
This CPU is the master of a VME crate which also contains V288 CAENet
controller modules (1 such module per 2 CAEN power supply crates) which send
control packets of words to the CAEN crates as determined by the C routines.
The C routines are invoked by a java GUI (see screen capture below) using
the CORBA protocol for remote procedure calls.
The interlock system ensures the SVX-II and ISL detectors are operated under
safe conditions.
The heart of the interlock system is a Siemens TI575 VME PLC (programmable
logic controller), which monitors silicon bulkhead temperatures and
cooling system values and interlocks the power to a particular section of
the SVX-II or ISL if these values are deemed out of range.
Monitoring of the whole system is achieved through a commercial software
package by Intellution called iFIX. Examples of the iFIX monitoring
pages are given below (not yet !) Documentation
