Class DigitalSensor

java.lang.Object

org.lsst.ccs.subsystems.fcs.DigitalSensor

All Implemented Interfaces:

BinarySensor, SensorPluggedOnDevice

public class DigitalSensor
extends Object
implements BinarySensor, SensorPluggedOnDevice

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.

Method Detail

getName

public String getName()

The name of this component.

Specified by:

getName in interface SensorPluggedOnDevice

Returns:

the name of this component

getByteNumero

public int getByteNumero()

Specified by:

getByteNumero in interface SensorPluggedOnDevice

getInputNumero

public int getInputNumero()

getDeviceName

public String getDeviceName()

Specified by:

getDeviceName in interface SensorPluggedOnDevice

isOn

@Command(type=QUERY,
         level=1,
         description="Return True if the sensor is ON")
public boolean isOn()

Specified by:

isOn in interface BinarySensor

updateValue

public void updateValue(int newValue)

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

Specified by:

updateValue in interface SensorPluggedOnDevice

Parameters:
