Class AutoChangerModule

java.lang.Object

java.util.Observable

org.lsst.ccs.framework.Module

org.lsst.ccs.subsystems.fcs.AutoChangerModule

All Implemented Interfaces:

Observer, org.lsst.ccs.framework.Configurable, org.lsst.ccs.framework.HardwareController, org.lsst.ccs.framework.SignalHandler

public class AutoChangerModule
extends org.lsst.ccs.framework.Module
implements org.lsst.ccs.framework.HardwareController

This class is used with the final hardware in which we have a clamp online to hold the filter at online position. It's not used for Single Filter Test but is used for testbenchCPPM.

public int getStandbyPosition()

getLatches

public AutochangerTwoLatches getLatches()

getTrucks

public AutoChangerTrucksModule getTrucks()

getOnlineClamps

getPlutoGateway

public PlutoGatewayModule getPlutoGateway()

isLoaderConnected

@Command(type=QUERY,
         level=0,

public boolean isLoaderConnected()

Returns the boolean field loaderConnected. If the loaderConnected boolean is being updated and waits for a response from a sensor, this methods waits until loaderConnected is updated. If the field loaderConnected is not being updated, it returns immediatly the field loaderConnected.

Returns:

                                                    throws org.lsst.ccs.HardwareException

Specified by:

checkHardware in interface org.lsst.ccs.framework.HardwareController

Throws:

org.lsst.ccs.HardwareException

checkStarted

public void checkStarted()
                  throws org.lsst.ccs.HardwareException

Specified by:

Throws:

org.lsst.ccs.HardwareException

checkStopped

public void checkStopped()
                  throws org.lsst.ccs.HardwareException

This method is executed during a shutdown of the subystem to prevent a shutdown when some hardware is moving. Nothing to do here because all the moving hardware of the autochanger is represented by the class MobilItemModule where the method checkStopped is implemented.

Specified by:

checkStopped in interface org.lsst.ccs.framework.HardwareController

Throws:

org.lsst.ccs.HardwareException
