org.lsst.ccs.framework.Module

org.lsst.ccs.subsystems.fcs.ComplementarySensors

All Implemented Interfaces:

Observer, org.lsst.ccs.config.ConfigurationBulkChangeHandler, org.lsst.ccs.framework.Configurable, org.lsst.ccs.framework.HasLifecycle, org.lsst.ccs.framework.SignalHandler, AlertRaiser, org.lsst.ccs.UsesSubsystem

public class ComplementarySensors
extends org.lsst.ccs.framework.Module
implements AlertRaiser

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)
