public class CanOpenDIO
extends CompactIOModule
implements PieceOfHardware

This is the driver class for the Digital-Input-Output we use in the FCS: CAN-CBX-DIO8. A CAN-CBX-DIO8 has 8 inputs or outputs. At the initialization, it has to be configured to say which are the inputs and which are the ouputs. The outputs for the standby or standback motors of the autochanger are on this device. The sensors to know if a latch on the autochanger is closed or open are also connected to a CAN-CBX-DIO8.

CanOpenDIO

public CanOpenDIO()

CanOpenDIO

public CanOpenDIO(String nodeID,
                  String serial)

Method Detail

initModule

public void initModule()

Overrides:

initModule in class CompactIOModule

getSerialNB

public String getSerialNB()

Specified by:

getSerialNB in interface PieceOfHardware

getNodeID

public String getNodeID()

Specified by:

getNodeID in interface PieceOfHardware

setSerialNB

public void setSerialNB(String serialNB)

Parameters:

serialNB - the serialNB to set

setNodeID

public void setNodeID(String nodeID)

Parameters:

nodeID - the nodeID to set

isInitalized

public boolean isInitalized()

Specified by:

isInitalized in interface PieceOfHardware

Returns:

true if the hardware has been initialized with success, false otherwise.

isNodeIdBootedAndOK

public boolean isNodeIdBootedAndOK()

Specified by:

isNodeIdBootedAndOK in interface PieceOfHardware

Returns:

true If this piece of hardware is booted and the nodeID on the hardware is the same than the one in the Configuration DB.

writeDigitalOutput

public String writeDigitalOutput(int outputNB,
                                 int value)
                          throws SDORequestError,
                                 HardwareNotDetectedException

Write a value to the output of the DAC

Parameters:

outputNB - in 1..8

value - given in decimal format TODO chnage this : it's not so simple !

Throws:

SDORequestError

HardwareNotDetectedException

readNewHexaValue

public String readNewHexaValue()

returns the value in hexa of all the sensors connected on the inputs channels of the device. cf CAN-CBX-DIO8 examples : if returns "80" means that the input 8 is set to 1, the others to 0 if returns "A0" means that the inputs 7 and 5 are set to 1, the others to 0 if returns "FF" all the inputs are set to 1 if returns "00" all the inputs are set to 0

Specified by:

readNewHexaValue in class CompactIOModule

Returns:

a String which is the value in hexa sent by the device.

writeMask

public String writeMask()
                 throws SDORequestError

This methods initialize the CAN-CBX-DIO8 with the mask (value 3) to configure the 2 first channels of the device to be output channel. (3 = 00000011)

Returns:

mask Value as a String (hexa)

Throws:

SDORequestError

checkMask

public boolean checkMask()
                  throws SDORequestError

This methods checks if the mask of the device is the good one. The good one is when the first 2 channels are output channels, that means that the value of the mask is 3 (3= 00000011)

Returns:

true if the mask is OK, false otherwise

Throws:

SDORequestError

readNewValue

public int readNewValue()

Description copied from interface: Sensor

This method reads the current value in decimal measured by the hardware or compute a random value for the simulated sensor, and returns this current value.

Specified by:

readNewValue in interface Sensor

Returns:

the current value provided by the real or simulated sensor.

initializeHardware

public String initializeHardware()
                          throws Exception

Description copied from interface: PieceOfHardware

This methods write some configuration data on the hardware CPU.

Specified by:
