Development of the MADOCA-to-EPICS gateway

For the new device evaluation towards the SPring-8 upgrade project, we were faced with a request to temporarily integrate the new BPM signal processing system (Libera Brilliance+) with built-in EPICS IOC into the SPring-8 storage ring control system. We have developed the MADOCA-to-EPICS gateway. In the equipment control layer of MADOCA, Equipment Manager (EM) is deployed on the front-end computers. The MADOCA-to-EPICS gateway is implemented as general-purpose EM to deal with EPICS IOCs. The gateway consists of general EM functions for interacting with IOC using Channel Access (CA), which are corresponding to the command such as caput, caget and camonitor in the EPICS system. We can build the gateway by specifying EM functions for CA and PV names in the EM configuration file. We will report on the development of the MADOCA-to-EPICS gateway and an application to the evaluation system of Libera Brilliance+ installed into the SPring-8 storage ring. (author)
