PowerSupply

Powersupplies are very common devices found in accelerators. They are used to contain and guide the beam. They can be controlled in voltage and current. Powersupplies come in many different types. Some of them are very complicated e.g. ramping and ac-dc powersupplies. The abstract class proposed here is for a simple powersupply. Other abstract classes can be developed to cater for the more complicated cases.

Version 1

Commands

The following commands must be implemented :

1. On - switch the powersupply on (state = ON)
   
2. Off - switch the powersupply off (state = OFF)
   
3. Reset - reset the powersupply (state = OFF)

Attributes

The following attributes must be implemented :

Attribute	Type	Access	Description
Current	DOUBLE	RW	current in amperes
Voltage	DOUBLE	RW	current in volts

States

The following states must be implemented :

1. ON - powersupply is switched on and delivers current
2. OFF - powersupply is switched off and does not deliver current
3. FAULT - powersupply is in fault

The following states are optional :

1. STANDBY - powersupply is ready to deliver current

Implementations

This is a proposal, there are currently no known implementations.
