EPICS CA Gateway Employment in the BEPCII Network

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 control network of the BEPCII is divided into two separate different subnets in the control network. In order to access IOC PVs between the separate subnets as well as IOC PVs from the campus network, EPICS CA gateway has been employed in the BEPCII network. This paper introduces the Gateways application in the BEPCII control network and describes the procedures of the Gateway setup as well as the test result.
