Class BridgeToCanOpenHardware

java.lang.Object

java.util.Observable

org.lsst.ccs.framework.Module

org.lsst.ccs.subsystems.fcs.drivers.BridgeToCanOpenHardware

All Implemented Interfaces:

Serializable, Observer, org.lsst.ccs.framework.Configurable, BridgeToHardware

Direct Known Subclasses:

BridgeForAPCTestBench, BridgeForCPPMTestBench, BridgeForLPSCTestBench, BridgeToChanger, BridgeToLoader, BridgeToSFTHardware

public abstract class BridgeToCanOpenHardware
extends org.lsst.ccs.framework.Module
implements BridgeToHardware

This class gathers the description of the real hardware and the tools (methods) to give access to this hardware. The concrete classes which extends this abstract class will have to add the fields for the pieces of hardware and to give the list of hardware in the method listHardware.

Constructor Detail

BridgeToCanOpenHardware

public BridgeToCanOpenHardware(String aName,
                       int aTickMillis,
                       CanOpenProxy tcpProxy)

Method Detail

listHardware

public abstract PieceOfHardware[] listHardware()

This method returns the list of hardware that this bridge will manage.

Returns:

a list of PieceOfHardware exemple : public PieceOfHardware listHardware() { PieceOfHardware[] hardwareList = {clampActuatorXminus, clampActuatorXplus, ai814, ao412, dio8n1, dio8n2}; return hardwareList; }

getTcpProxy

public CanOpenProxy getTcpProxy()

Specified by:

getTcpProxy in interface BridgeToHardware

startThreadReader

public void startThreadReader()

Specified by:

startThreadReader in interface BridgeToHardware

isCWrapperConnected

public boolean isCWrapperConnected()

This method returns true if the C-Wrapper is connected to the tcp proxy. The C-Wrapper has to send the tcpProxy clientName as a keyword before any communication can begin. So if the C-Wrapper doesn't send the good keyword or if it doesn't connect to the tcp proxy, this method returns false.

Specified by:

isCWrapperConnected in interface BridgeToHardware

isHardwareReady

public boolean isHardwareReady()

returns true if the hardware is booted, identified and initialized.

Specified by:

isHardwareReady in interface BridgeToHardware

initModule

public void initModule()

Overrides:

initModule in class org.lsst.ccs.framework.Module

sendCanOpen

public Object sendCanOpen(String command)
                   throws InterruptedException,
                          TimeoutException,
                          org.lsst.ccs.bus.BadCommandException

For engineering mode, this method can be used to send Can Open commands to the Wrapper.

Parameters:

command - A Can Open command that the Wrapper should understand.

Returns:

the response from the Wrapper

Throws:

InterruptedException

TimeoutException

org.lsst.ccs.bus.BadCommandException

readPDOs

public CanOpenProxy.PDOStorage readPDOs()
                                 throws HardwareException,
                                        org.lsst.ccs.bus.BadCommandException

Specified by:

readPDOs in interface BridgeToHardware

Throws:

HardwareException

org.lsst.ccs.bus.BadCommandException

toString

public String toString()

Overrides:

toString in class Object
