Class Summary

Class	Description
Autochanger	This class is used with the final hardware and prototype in which we have online clamps to hold the filter at online position.
AutochangerLatch	This class is a model for the latch which lock a filter on the autochanger trucks.
AutochangerMain	This class is the Main Module when autochanger is in standalone mode.
AutochangerOnlineClamp	This is a model for online clamp which holds a filter when it is at ONLINE position.
AutochangerThreeOnlineClamps	The Three Online clamps which holds a filter when it is at ONLINE position can ve viewed as a single object.
AutochangerTruck	A model for an autochanger truck.
AutochangerTwoLatches	This class represents a model for the 2 Latches of the autochanger.
AutochangerTwoTrucks	This is a model for autochanger trucks.
Carousel	This is a representation of the hardware of the carousel.
CarouselClamp	A class to model a clamp that holds a filter on the carousel.
CarouselClampSensor
CarouselMain	This class is the Main Module when carousel is in standalone mode.
CarouselSensor	A model for the carousel sensors.
CarouselSocket	This is a socket on the carousel : there is 5 sockets on a carousel.
ComplementarySensors	Represents a couple of DigitalSensor which are complementary : when one has the value 1 the other must have value 0 and vice versa.
DigitalSensor	This class represents a sensor which sends 0 or 1.
FakeFilterHolder	This class is a model for the fakeAutochanger that we use on loader and carousel test bench in standalone mode.
FcsMain	The main module in FCS.
Filter	This is a model for an optical filter for the camera.
FilterIdentificator	This is a Model for the system which identifies filters on the autochanger trucks.
FilterManager	This class's goal is to manage the filters.
ForceSensor	Represents a model for a force sensor.
Inclinometer	This is a model for the Inclinometer used in CPPM test bench and on whole size prototype.
Loader	This is the model for the loader in the Filter Exchange System.
LoaderCarrier	This is a model for the carrier in the loader.
LoaderClamp	This is model for the clamps mechanism in the loader.
LoaderHook	This is the model for a single hook in the loader.
LoaderMain	This is the Main Module for the Loader control software when the loader is in standalone.
MainModule	This is the Main Module for every software related to the Filters Exchanger : - single-filter-test control-command - scale 1 prototype control-command - real Filters Exchanger This class is designed to gather the commons methods to all these softwares.
RedondantSensors	Represents a couple of sensors which are redondant : that means they must have the same digitalValue.

Package org.lsst.ccs.subsystems.fcs Description

This package is for the control software of the LSST camera Filter Exchanger Subsystem. It contains many subpackages for the test stands, for the GUI, for commons stuff, for simulation classes or for real drivers classes. The control softwares for the test stands could probably go in another place, because they will be used only during the construction of the camera. Here are the test stands we have :

• singlefiltertest: The test for the clamps.
• testbench: a small test stand in APC to test the communication with the can open drivers.

The FCS is a Modular Subsystem, a set of Modules that listens each other. This Modules are assembled within an xml file. The 4 most important Modules are :

• Autochanger: The main Module for the control of the autochanger.
• CarouselModule: The main Module for the control of the carousel.
• LoaderModule: The main Module for the control of the loader.
• FcsMainModule: The main Module for the control of the fcs viewed as a whole subsystem.

For each piece of hardware that moves or can be controled, there is a Module and an interface in the subpackage common. The Module implements the interface. We can have the sofware for the simulator when we build the fcs with the hardware simulated classes in the package simulation or we can have the control software for the hardware when we build the fcs with the drivers classes in the package drivers.
