This ability is also exposed if you use CSS-BOY and install the webopi.

It works fairly well, but it is a bit slow if you intend to use it for read-write access of "live" controls.

If using HTTP is seen as a perk because no one has to configure client software in order to view screens, let me point out that caQtDM (easily downloadable on computers, tablets, phones) also allows one to point to an HTTP (via -httpconfig) configuration location that specifies setup and network display screen locations. So one could use punchier technology to provide information on a "write once, use by many people" basis, assuming the client software has access to wherever this information is hosted/made available.

Subject: HTTP access to control systems screens

At the meeting last week we had two presentations on efforts to display live control screens in browser.

I have an internal effort at LIGO where I am translating our MEDM .adl files to html/svg/js. If there is interest in the community I would rather focus on an effort larger than myself.

Feel free to contact me on/off list.

Thanks,
