Direct Known Subclasses:

SimuCompactIO

public class CompactIO
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

Build a new CompactIOModule

Parameters:

nodeID -

serialNB -

Method Detail

readNewHexaValue

public int 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

Returns:

value in hexa read on the device

Throws:

FcsHardwareException

getHexaValue

public int 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

writeDigitalOutput

public String writeDigitalOutput(int outputNB,
                                 int value)

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

writeMask

public String writeMask()

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

checkMask

public boolean checkMask()

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
