Communicate between XML-RPC system and EPICS Channel Access?

[Russell Kackley <rkackley@naoj.org>]

Hi All,

Subaru Telescope has a new laser system coming in soon and there is a proposal to use EPICS software from Keck and Gemini to control the laser. Subaru, Keck, and Gemini are going to be sharing laser system spare parts, so it would make sense for us to also share the laser control software. However, we don't currently have EPICS installed anywhere at Subaru. We currently have our Observation Control System (OCS) using XML-RPC to communicate between processes distributed among various computers. We really need the OCS to be able to communicate with the laser system, i.e., send control messages from the XML-RPC based system to EPICS Channel Access and receive status back along the same path.

My question is: has anyone done any work to enable communication between an XML-RPC system and EPICS Channel Access? Thanks in advance for any suggestions.
