Next: Initial Requirements
Abstract:
TRIUMF's
SR User Facility required a slow control system for
the VAX/VMS platform that would allow online database
modification, quick implementation of new instrument drivers and
integration into the existing data acquisition system.
Most of the instrumentation in use at the
SR User Facility
have complex functionality and well-defined communications protocol.
The CAMP (Control And Monitoring of Peripherals) Slow Control
System has been developed to meet these
requirements. The fulfilment of the initial requirements, and
the upgrades made after over one year's use in the field will be
discussed. The use of ONC (Sun) RPCs for communication,
the Tcl interpreted language for instrument driver programming,
and DECthreads for multithreading the server are explained.
The
SR User Facility at TRIUMF consists of four beamlines,
each using a VAX and single CAMAC crate for data acquisition.
