Class Summary

Class	Description
AutoChangerModule	This class will be used with the final hardware in which we have a clamp online to hold the filter at online position.
BasicAutoChangerModule	An abstract changer module without a fliprail, without online clamp, and without a motor.
CarouselLatch
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.
ClampActuatorModule	A model for the clamp actuator.
CompactIOModule	This represents a device we use in FCS to connect our numeric sensors(CAN-CBX-DIO8).
FcsMainModule	The main module in FCS.
Filter	This is a model for an optical filter for the camera.
FilterClampModule	An abstract class which extends Module to model a clamp that holds a filter on the carousel.
FilterClampXminusModule
FilterLatchModule	This is a model for a latch.
LatchActuatorModule
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.
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.
PlutoGatewayModule	This represents the gateway to the pluto PLC involved in the camera protection system.
Sensor14bits	This class represents a 14bits sensor : the value returned by the sensor is coded with 14 bits, so its value is between 0 and 32760.
TruckModule	A truck is a mobile part in the autochanger.

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.
