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.
AutoChangerTrucksModule
AutochangerTwoLatches	This class represents a model for the 2 Latches of the autochanger.
CarouselClampModule	An abstract class which extends Module to model a clamp that holds a filter on the carousel.
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.
EmergencyMessage	This is a model for an Emergency message comming from the CANbus.
EPOSEnumerations	Here are 2 Enum : Parameter and EposMode
FcsEnumerations
FcsMainModule	The main module in FCS.
Filter	This is a model for an optical filter for the camera.
FilterClampXminusModule
InclinometerModule	This is a model for the Inclinometer used in CPPM test bench.
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 32767.
StatusDataPublishedByAPCTestBench
StatusDataPublishedByAutoChanger	A structure for the data published on the status bus by the AutoChangerModule.
StatusDataPublishedByAutochangerLatch	The data published on the Status Bus by a latch.
StatusDataPublishedByAutochangerOnlineClamp	Object published by an Autochanger Online Clamp.
StatusDataPublishedByAutochangerThreeClamps
StatusDataPublishedByAutoChangerTrucks	To publish on the status bus the AutoChangerTrucksModule data.
StatusDataPublishedByAutochangerTwoLatches
StatusDataPublishedByBasicAutoChanger	A structure for the data published on the status bus by a BasicAutoChangerModule.
StatusDataPublishedByCarousel	A structure for the data published on the status bus by the CarouselModule.
StatusDataPublishedByClamp	A structure for the data published on the status bus by the ClampModule.
StatusDataPublishedByClampActuator
StatusDataPublishedByEPOSController
StatusDataPublishedByFCS	Just to avoid having to change a bunch of classes when the core developpers change their mind about the interface to implement in the classes which describe objects to publish on the bus.

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.
