Class DigitalSensor

java.lang.Object

org.lsst.ccs.subsystems.fcs.DigitalSensor

All Implemented Interfaces:

org.lsst.ccs.framework.HasLifecycle, BinarySensor, SensorPluggedOnDevice

public class DigitalSensor
extends Object
implements BinarySensor, SensorPluggedOnDevice, org.lsst.ccs.framework.HasLifecycle

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.

Specified by:

build in interface org.lsst.ccs.framework.HasLifecycle

getName

public String getName()

The name of this component.

Specified by:

getName in interface SensorPluggedOnDevice

Returns:

the name of this component

getByteNumero

getByteNumero in interface SensorPluggedOnDevice

getInputNumero

public int getInputNumero()

getDeviceName

public String getDeviceName()

Specified by:

getDeviceName in interface SensorPluggedOnDevice

isOn

@Command(type=QUERY,
         level=1,
