Interface BridgeToHardware

All Known Implementing Classes:

CanOpenProxy, LoaderCanOpenProxy, SimuCanOpenProxy

public interface BridgeToHardware

This interface has to be implemented by classes which start a tcpip server to communicate with real hardware or by classes which simulate the communication with hardware.

Method Detail

checkHardware

org.lsst.ccs.framework.TreeWalkerDiag checkHardware()
                                             throws org.lsst.ccs.HardwareException

Throws:

org.lsst.ccs.HardwareException

connectHardware

void connectHardware()
              throws org.lsst.ccs.HardwareException

This method is used when the loader CANbus is connected.

Throws:

org.lsst.ccs.HardwareException

disconnectHardware

void disconnectHardware()

This methods stops the CWrapper client, and the TCP server.

printHardwareList

String printHardwareList()

Return a String with the list of hardware expected in this subsystem. For debug purpose.

Returns:

listHardwareNames

List<String> listHardwareNames()

Return an Array containing hardware names handled by this component.

Returns:

printHardwareState

String printHardwareState()

Return a printed list of hardware with the initialization state. For debug purpose.

Returns:

publishData

void publishData()

Publish Data on status bus for trending data base and GUIs.

isCWrapperConnected

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.

Returns:

isRealHardware

boolean isRealHardware()

Returns:

true if this bridge is connected with real hardware, false if the hardware is simulated.

isCANDevicesReady

boolean isCANDevicesReady()

Returns:

true if the hardware is booted, identified.

startServer

void startServer()

startThreadReader

void startThreadReader()

readPDOs

PDOStorage readPDOs()
