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.
