Abstract
Since the beginning of 1989, a new supervision system has been added to the GANIL control system in order to get a better view of data handled by programmable controllers. This supervisory system has been designed around software named IMAGIN, provided by the French company Sferca IMAGIN runs on VAX/VMS workstations and its graphic capabilities are based on the GKS IIc standard. It consists of software modules, including a graphic editor and a “configurer” used to create dynamic objects associated with external variables. The real-time display achieved by an “animator” process is synchronized with user software programs by means of mailboxes. This gives the whole system the capability of meeting any specific requirement. Moreover, this supervisory system is capable of controlling the programmable controllers as well as any processor which can be reached from the workstations. This paper describes the main features of IMAGIN software and then emphasizes some implementations which have been carried out at GANIL, to supervise either the programmable controllers or the existing control system.
