How is your interlock done?  Simple relays or with a PLC?  Our laser interlocks here at APS use inexpensive PLCs, and they directly operate the warning lights outside the enclosure.

Subject: Simple wireless light controlled through EPICS? 

Anyone have any suggestions for a simple way to control a light with EPICS? It does not need to be bright, even a small LED will do. Basically I'm trying to have indicators on several doorways to show the current status of the interlock on our x-ray source (which is already a PV).  

In the ideal scenario it would be connected to wifi so that ethernet/usb cables do not need to be run everywhere. I was thinking of maybe trying to get the "Belkin WeMo Home Automation Switch" to work with EPICS, it is basically a power plug that connects to WiFi. But it is probably easier to find some USB LEDs and run cables. 

I know some beamlines at APS have EPICS controlled lights, so wondering if anyone has ideas?


Thanks!
Andrew
