Class FcsMain

java.lang.Object

org.lsst.ccs.subsystems.fcs.MainModule

org.lsst.ccs.subsystems.fcs.FcsMain

All Implemented Interfaces:

org.lsst.ccs.framework.HasLifecycle, org.lsst.ccs.framework.SignalHandler, AlertRaiser

public class FcsMain
extends MainModule

The main module in FCS. Commands can be sent to the FcsMain from the CCS Master Control Module (MCM) in normal operation mode or from a Console (org.lsst.ccs.subsystem.console.TestConsole).

Example of commands that can be sent to the FcsMain :
Console> invoke fcs-test MoveFilterToOnline filtername

The main goals of the FcsMain is :

• Receive commands from MCM for the whole subsystem.
• Execute commands received from MCM in invoking methods on the Carousel Module on the Autochanger Module and on Loader Module.
• Handle the logic of the whole subsystem.
• Publish on the status bus the status of the whole subsystem.

Constructor Detail

FcsMain

public FcsMain(BridgeToHardware bridge,
               BridgeToHardware bridgeToLoader)

Build a FcsMainModule

Parameters:

bridge -

bridgeToLoader -

Method Detail

init

public void init()

updateFCSStateToReady

public void updateFCSStateToReady()

Description copied from class: MainModule

Updates the FCS state and FCS readyness state and publishes on the status bus. Checks that hardware is ready to be operated and moved. This means that : - all CAN open devices are booted, identified and initialized, - homing has been done on the controllers. This updates the FCS state and FCS readyness state and publishes on the status bus. This has to be overriden if there is other initializations to do on the hardware like homing.

Overrides:

updateFCSStateToReady in class MainModule

getOnlineFilterName

public String getOnlineFilterName()

Return the name of the filter which is at ONLINE. Return null if no filter is at ONLINE.

Returns:

printFilterONLINEName

@Command(type=QUERY,
         level=0,
         description="Returns the name of the filter which is at ONLINE.")
public String printFilterONLINEName()

For end user. Return the name of the filter which is at ONLINE. Return null if no filter is at ONLINE.

Returns:

getFilterByName

@Command(type=QUERY,
         level=0,
         description="returns the filter which has for name the String given as argument.")
public Filter getFilterByName(String filterName)

This methods returns the filter which has for name the String given as argument.

Parameters:

filterName -

Returns:

isChangerConnected

@Command(type=QUERY,
         level=0,
         description="Return true if the changer is connected.")
public boolean isChangerConnected()

Return true if the changer is connected.

Returns:

isLoaderConnected

@Command(type=QUERY,
         level=0,
         description="Return true if the loader is connected.")
public boolean isLoaderConnected()

Return true if the loader is connected.

Returns:

isChangerReady

@Command(type=QUERY,
         level=0,
         description="Return true if the hardware of the changer is ready.")
public boolean isChangerReady()

Return true if the hardware of the changer is ready.

Returns:

isLoaderReady

@Command(type=QUERY,
         level=0,
         description="Return true if the hardware of the loader is ready.")
public boolean isLoaderReady()

Return true if the hardware of the loader is ready.

Returns:

disconnectLoader

@Command(type=ACTION,
         level=0,
         description="Disconnect the loader hardware.")
public void disconnectLoader()

Disconnect the loader hardware.

connectLoader

@Command(type=ACTION,
         level=0,
         description="Connect the loader hardware.")
public void connectLoader()

Connect the loader hardware.

checkFilterName

public void checkFilterName(String aName)

Check if a filter name given by an end user at the console is a valid Filter Name. Delegate to filterManager.

Parameters:

aName -

checkAutochangerTrucksLocation

public void checkAutochangerTrucksLocation()

Check where are the autochanger trucks. If a filter is at ONLINE position update state and publishes.

listLoaderHardwareNames

@Command(type=QUERY,
         level=1,
         description="Return the list of LOADER CANopen hardware that this subsystem manages.")

Returns:

setFilter

@Command(type=ACTION,
         level=0,
         description="Move filter to ONLINE position.",
         alias="setFilterONLINE",
         timeout=60)
public void setFilter(String letter)

Move a filter to ONLINE position. The filter must be in the camera. It can be on the carousel or on the autochanger. It envolves the carousel Module and the autochanger Module. If the filter we want to move is on the autochanger, the autochanger has to move it to ONLINE position. If the filter is on the carousel, and the autochanger truck is loaded with another filter, the autochanger has to move back the other filter on the carousel at standby position. If the filter is on the carousel and the autochanger is empty, we have to rotate the carousel in order to put the required filter at standby position, then the autochanger grabbes the filter on the carousel and moves it to ONLINE position.

Parameters:

letter - name of the filter to move

Throws:

FcsHardwareException

changeState

@Command(type=ACTION,
         level=0,
         description="change subsystem state.")
public void changeState(String state)

just for mcm testing

Parameters:

state -

loadFilter

public void loadFilter(Filter aFilter)

Load a filter from the loader to the camera. At the end of this operation the filter is grabbed on the autochanger at Handoff position.

Parameters:

unloadFilter

public void unloadFilter(Filter aFilter)

Unload a filter from the camera to the loader. The camera has to be at horizontal position. The filter has to be on Carousel at STANDBY. The trucks of the autochanger have to be empty at STANDOFF position.

Parameters:

aFilter -

Throws:
