Abstract

The processing of high-level system commands within an experimental physics and industrial control system (EPICS) database application shares many issues with the design of EPICS motor control records in that the traditional synchronous/asynchronous record processing model is not adhered to. This paper presents the design of the Gemini CAD (command action directive) and CAR (command action response) EPICS database records and illustrates their use in a telescope mount control context dealing with the handling of repeated offset and slew commands.
