Class ComplementarySensors

java.lang.Object

org.lsst.ccs.subsystems.fcs.ComplementarySensors

All Implemented Interfaces:

org.lsst.ccs.framework.HasLifecycle, BinarySensor

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

Represents a couple of DigitalSensor which are complementary : when one has the value 1 the other must have value 0 and vice versa. If both sensors have the same value, the couple of sensors is in error. This sort of sensors are used in autochanger. The goal is to be able to detect errors in sensors (capteur défectueux, error de câblage)
