public BonnDevice()

Method Detail

initDevice

protected void initDevice()

Performs basic initialization. Verify that all ConfigurationParameters are set.

Overrides:

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

initialize

protected void initialize()

Performs full initialization.

Specified by:

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

canClearAlert

public org.lsst.ccs.framework.ClearAlertHandler.ClearAlertCode canClearAlert(org.lsst.ccs.bus.data.Alert alert,
                                                                             org.lsst.ccs.bus.states.AlertState alertState)

Tests whether WRONG_STATE alert can be cleared. Allow it to be cleared if shutter is now in CLOSED state.

Specified by:

canClearAlert in interface org.lsst.ccs.framework.ClearAlertHandler

Parameters:

Alert - - the Alert being testsd

AlertState - - state of Alert being tested

Returns:

ClearAlertCode

close

protected void close()

Closes the connection.

Specified by:

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

checkChannel

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

Checks a channel's parameters for validity. The only channel types which appear useful are two voltage readings.q For an invalid channel name, ErroTUtils will throw Exception.

Overrides:

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

Parameters:

chName - The channel name

hwChan - The hardware channel number

type - The channel type string

subtype - The channel subtype string

Returns:

A two-element array containing the encoded type [0] and subtype [1] values.

Throws:

Exception

readChannel

protected double readChannel(int hwChan,
                             int type)

Reads a channel.

Overrides:

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

Parameters:

hwChan - The hardware channel number.

type - The encoded channel type returned by checkChannel.

Returns:

The read value

reset

         level=1,
         name="reset",
         description="reset (after an error condition)")
public void reset()
                                                                                                                                   throws org.lsst.ccs.drivers.commons.DriverException

Throws:

org.lsst.ccs.drivers.commons.DriverException

readInfo

@Command(type=QUERY,
         level=0,
         name="readInfo",
         description="Read some shutter parameters and data")
public String readInfo()

Read some parameters and data from shutter controller All DriverExceptions are caught; if one occurs, the data field is replaced by the text (String) associated with the exception.

Returns:

String reporting all information read and exceptions.
