Framework for back-up and restore under the Experimental Physics and Industrial Control System

摘要

EPICS is a system that allows one to design and implement a controls system. In EPICS, devices controlled by an input/output controller (IOC) are represented by software entities called process variables. Under this schema, distributing processing over a number of IOCs and representing devices with process variables, there are a variety of ways one can view or group the information in the control system. The authors propose a framework which describes a system that periodically records and preserves the values of key process variables so that later on, those values can be written to the machine in an attempt to restore it to that same state.
