locateFilter

@Command(type=QUERY,
         level=0,
         description="Read the sensors and update location of the filter and state of Carousel and Autochanger.")
public void locateFilter()

Read the sensors and update location of the filter and state of Carousel and Autochanger.

Throws:

FcsHardwareException

checkPreConditionsForUnlockClamps

@Command(type=QUERY,
         level=1,
         description="Check if the carousel is ready to unlock the clamps in a safe way for the filter.",
         alias="checkUnlock")
public void checkPreConditionsForUnlockClamps()

Check if the carousel is ready to unlock the clamps in a safe way for the filter.

Throws:

FcsHardwareException

goToInitialState

@Command(type=ACTION,
         level=1,
         description="Move the hardware to the initial state : ")
public String goToInitialState()

Initial state for sequence1 : autochanger is in highposition and trucks are empty carousel holds a filter and its clamps are in CLAMPEDONFILTER state.

Returns:

Throws:

FcsHardwareException

executeSequence1

@Command(type=ACTION,
         level=0,
         description="The world famous sequence 1",
         alias="es1")
public String executeSequence1()

This method is the main sequence of commands that we want to test on the Single Filter Test. It executes this sequence of commands once. From the initial position (autochanger trucks empty in the higher position) :

• the autochanger trucks go down along the rails to standby position,
• the autochanger grabs the filter at standby position,
• the carousel ungrabs the filter at standby position,
• the autochanger moves the filter to the higher position,
• the carousel releases the clamps to be ready to clamp a filter again,
• the autochanger moves back the filter at standby position,
• the carousel checks if the filter is clamped at standby position,
• the autochanger ReleaseBrakes the filter latches,
• the autochanger trucks go empty to the higher position.

Returns:

a message for the operator

Throws:

FcsHardwareException

executeSequence1

@Command(type=ACTION,
         level=0,
         description="The world famous sequence 1 (with number of repetitions)",
         alias="es1")
public String executeSequence1(@Argument(name="nExecutions",description="Number of executions")
                                                                                                                                                                              int nb)

This method will execute nb times the Sequence1 : the parameter nb is given by the user at the console.

Parameters:

nb - : number of times we want to execute the Sequence1

Returns:

Throws:

FcsHardwareException

updateStateWithSensors

@Command(type=QUERY,
         level=1,
         description="Read the sensors and update the state of the carousel and the autochanger.")
public void updateStateWithSensors()

This command updates the state of the carousel and of the autochanger in reading the sensors. It has to be used in Engineering mode at the console when we send commands step by step.

Overrides:

updateStateWithSensors in class MainModule

Throws:

FcsHardwareException
