Experience with the EPICS PV Gateway at the APS.
The EPICS Process Variable Gateway has become a stable, high-performance application that provides access to process variables while minimizing the impact on critical Input-Output Controllers (IOCs) and implementing additional access security. The additional access security typically prevents write access but is highly configurable. The Advanced Photon Source (APS) currently uses 40 Gateways running on 11 workstations to provide access to the machine subnet from the offices and for the individual experimental teams. These include reverse Gateways that allow administration of all 40 APS Gateways from a single MEDM screen, even though the Gateways are running on separate networks. This administration includes starting, stopping, making and viewing reports, and viewing and editing access security files. There is one Gateway that provides process variable renaming. This paper provides an overview of the Gateways at the APS and describes the procedures that have been set up to use and administer them.
