Interface Summary

Interface	Description
FilterLocator	This interface is to factorise code between main Module for carousel in standalone mode and main Module for whole fcs.

Class Summary

Class	Description
AutochangerLatchModule	This class is a model for the latch which lock a filter on the autochanger trucks.
AutochangerMainModule	This class is the Main Module when autochanger is in standalone mode.
AutoChangerModule	This class is used with the final hardware in which we have a clamp online to hold the filter at online position.
AutochangerOnlineClampModule	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.
AutochangerTruckModule	A model for an autochanger truck.
AutochangerTwoLatches	This class represents a model for the 2 Latches of the autochanger.
AutoChangerTwoTrucksModule	This is a model for the autochanger trucks.
CanOpenNumericSensor	This is a model for the numeric sensors we have in single-filter-test and the loader, to monitor the latches in the autochanger, the autochanger trucks position in single-filter-test and the loader hooks.
CarouselClampModule	A class which extends Module to model a clamp that holds a filter on the carousel.
CarouselMainModule	This class is the Main Module when carousel is in standalone mode.
CarouselModule	This is a representation of the hardware of the carousel.
CarouselSocket	This is a socket on the carousel : there is 5 sockets on a carousel.
ComplementarySensors	Represents a couple of NumericSensor which are complementary : when one has the value 1 the other must have value 0 and vice versa.
FakeFilterHolder	This class is a model for the fakeAutochanger that we use on loader and carousel test bench in standalone mode.
FcsMainModule	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.
InclinometerModule	This is a model for the Inclinometer used in CPPM test bench and on whole size prototype.
LoaderCarrierModule	This is a model for the carrier in the loader.
LoaderClampModule	This is model for the clamps mechanism in the loader.
LoaderHookModule	This is the model for a single hook in the loader.
LoaderMainModule	This is the Main Module for the Loader control software when the loader is in standalone.
LoaderModule	This is the model for the loader in the Filter Exchange System.
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.
NumericSensor	This class represents a numeric sensor which sends a digitalValue 0 or 1.
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 :

• AutoChangerModule: 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.
