EPICS ON THE WEB
A. Bertr, R. Krempaská · 2005
Most of the scientific instruments at the Swiss Light Source (SLS) at PSI are controlled using the EPICS[1] control system, which offers many solutions to easy implement applications, but they are platform dependent. For developing users' services, the platform independence and remote access are starting to be mandatory. To fulfill those needs, we have developed an interface between the EPICS channel access protocol and the PHP[2] Web scripting language. In order to speedup the development of the epics web accessibility, a MEDM parser/interpreter has been developed using the PHP Epics module. Using this software (WebMEDM), most MEDM[3] panels are directly, without any further work accessible via a web browser, allowing remote controls of the beamlines. The resulting HTML pages have the same look and feel as their MEDM counterpart and all the dynamic values contained are updated in real-time as the original.
