Constructor Detail

PduCommonDevice

public PduCommonDevice()

Method Detail

initDevice

protected void initDevice()

Performs configuration.

Overrides:

initDevice in class org.lsst.ccs.monitor.Device

initialize

public void initialize()

Performs full initialization.

Specified by:

initialize in interface SwitchControl

Specified by:

initialize in class org.lsst.ccs.monitor.Device

close

protected void close()

Closes the connection.

Specified by:

close in class org.lsst.ccs.monitor.Device

checkChannel

protected int[] checkChannel(String name,
                             int hwChan,
                             String type,
                             String subtype)
                      throws Exception

Checks a monitoring channel's parameters for validity. Only the type can be checked at this time.

Overrides:

checkChannel in class org.lsst.ccs.monitor.Device

Parameters:

name - The channel name

hwChan - The hardware channel

type - The channel type string

subtype - The channel subtype string

Returns:

Two-element array containing the encoded type [0] and subtype [1]

Throws:

Exception - If parameters are invalid

initChannel

protected void initChannel(String name,
                           int id,
                           int hwChan,
                           int type,
                           int subtype)

Initializes a monitoring channel. This is used here only to check the hardware channel number, since the allowed range is known only after the device is opened.

Overrides:

initChannel in class org.lsst.ccs.monitor.Device

Parameters:

name - The channel name

id - The channel ID

hwChan - The hardware channel

type - The channel type string

subtype - The channel subtype string

readChannel

protected double readChannel(int hwChan,
                             int type)

Reads a monitoring channel.

Overrides:

readChannel in class org.lsst.ccs.monitor.Device

Parameters:

hwChan - The hardware channel number

type - The encoded channel type

Returns:

The read value

getSwitchDevice

public int getSwitchDevice()

Gets the switch device type

Specified by:

getSwitchDevice in interface SwitchControl

Returns:

The switch device type

switchOn

public void switchOn(int chan)

Turns a PDU channel on.

Specified by:

switchOn in interface SwitchControl

Parameters:

chan - The channel number

switchOff

public void switchOff(int chan)

Turns a PDU channel off.

Specified by:

switchOff in interface SwitchControl

Parameters:

chan - The channel number

isSwitchOn

public Boolean isSwitchOn(int chan)

Gets the state of a PDU channel.

Specified by:

isSwitchOn in interface SwitchControl

Parameters:

chan - The channel number

Returns:

Whether the channel is on or off
