Controls

The frontend exposes for each socket two ODB keys:

Socket n requested => indicates the requested state for the socket number n
Socket n current   => indicates the current state of the socket number 

There are 3 state currently supported:

• On
• Off
• Restart

Dynamic grow / shrink

This frontend will detect the number of sockets that EPICS declares. It will adapt accordingly. This feature also works at runtime.
