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.

Russell,

not RPC-XML, but if you look at the channel access part of e.g. tide

(which I know you know) you may be able to plug that into your existing

system.
