public class CompactIOModule
extends CanOpenDevice

This represents a device we use in FCS for to connect our numeric sensors(CAN-CBX-DIO8). It has 8 channels. Each channel can be configured to be inputs or output channel. So we can plug up to 8 sensors on one CampactIOModule. We read all the inputs channels in the same commands. 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. This class raises alerts : - FCS004 in readNewHexaValue

Constructor Detail

CompactIOModule

public CompactIOModule(String aName,
                       int aTickMillis,
                       String nodeID,
                       String serialNB)

Method Detail

initModule

public void initModule()

Overrides:

initModule in class CanOpenDevice

readNewHexaValue

public String readNewHexaValue()
                        throws FcsHardwareException

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

Returns:

value in hexa read on the device

Throws:

FcsHardwareException

getHexaValue

public String getHexaValue()

Returns:

the hexa value converted in decimal.

getValue

public int getValue()

Returns:

the hexa value converted in decimal.

updateValue

public void updateValue()
                 throws FcsHardwareException

Throws:

FcsHardwareException

writeDigitalOutput

public String writeDigitalOutput(int outputNB,
                                 int value)
                          throws SDORequestException,
                                 HardwareNotDetectedException,
                                 FcsHardwareException

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 !

Returns:

Throws:

SDORequestException

HardwareNotDetectedException

FcsHardwareException

writeMask

public String writeMask()
                 throws SDORequestException,
                        FcsHardwareException

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:

SDORequestException

FcsHardwareException

checkMask

public boolean checkMask()
                  throws SDORequestException,
                         ShortResponseToSDORequestException,
                         FcsHardwareException

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:

SDORequestException

ShortResponseToSDORequestException

FcsHardwareException
