org.lsst.ccs.subsystems.fcs.DigitalSensor

All Implemented Interfaces:

BinarySensor

public class DigitalSensor
extends Object
implements BinarySensor

This class represents a sensor which sends 0 or 1. This is a model for the digital sensors we have in single-filter-test, the loader, to monitor the latches in the autochanger, the autochanger trucks position in single-filter-test and the loader hooks. Value sent by this type of sensor is 0 (false) or 1 (true). This type of sensors are used in the autochanger for the rail filter presence sensor : the sensors which detects if a filter is there or not on each side of the rail and at standby and standback position. This is used too to monitor the autochanger latches : to know if a latch is locked or unlocked. This is also used in the loader test bench where the sensors are connected to a Pluto PLC for the camera protection system. We read the sensors through a Gateway (CanOpenPlutoGateway) byte by byte. So we need to know on which byte this sensor is coded.

Field Detail

byteNumero

@ConfigurationParameter(range="0..15",
                        description="The numero of the byte where the value of this sensor is stored in.")
protected int byteNumero

Gateway byte number where the sensor is coded. value = 1 or 2 in january 2014 value = 0,1,2,3,4,5 in december 2014

on

protected boolean on

this represents the value sent by the sensor. If sensor sent value 1, on = true. If sensor sends value 0, on = false;

Constructor Detail

DigitalSensor

public DigitalSensor(String dioName,
                     int inputNumero)

Build a new DigitalSensor.

Parameters:

dioName - name of the CANopen dio device where this sensor is plugged on.

inputNumero -

DigitalSensor

public DigitalSensor(String dioName,
                     int inputNumero,
                     int byteNumero)

Build a new DigitalSensor which is plugged on a plutoGateway for example.

Parameters:

inputNumero -

byteNumero -

Method Detail

getName

public String getName()

The name of this component.

Returns:

the name of this component

getByteNumero

@Command(type=QUERY,
         level=1)
public int getByteNumero()

getInputNumero

@Command(type=QUERY,
         level=1)
public int getInputNumero()

isOn

@Command(type=QUERY,
         level=1)
public boolean isOn()

Specified by:

isOn in interface BinarySensor

updateValue

public void updateValue(int hex)

This methods updates the digital value for this sensor. It takes as an argument the value in hexa sent by the CompactIOModule. This hexa value represents the 8 values for the 8 channels. example if hex = 80, and inputNumero=7, digital value=1 otherwise digital value=0.

Parameters:

hex -

updateValue

public void updateValue(int[] hexaValues)

Update the field on from the bytes read on the gateway.

Specified by:

updateValue in interface BinarySensor

Parameters:

hexaValues -

toString

@Command(type=QUERY,
         level=1,
         alias="printValue")
public String toString()

Overrides:

toString in class Object
