To prepare an autorun sequence, a set of standard commands are available to:

• Modify the Parameters of a Device -- SET command
• Perform a Run in an Autorun Sequence
• Wait for Special Conditions
  • wait_time_auto
  • wait_temp_auto
• Change the Titles of the Run
• Document the Autorun Sequence

Modify the Parameters of a Device -- SET command

To modify the parameters of a device, the command SET should be used:

Syntax:

SET  <alias>|<equipment name> [<device specific arguments>]

Examples:

• Setting the Cryostat Temperature (2-loops mode):

  SET Temperature 100.0 1.0 60 100.0 1.5 30
  

  where:
  • Temperature represents the alias for the temperature controller frontend,
  • 100.0 represents the new setpoint in Kelvin for the first heating loop,
  • 1.0 represents the tolerance in Kelvin for the first heating loop,
  • 60 represents the time that the first temperature needs to stay within the tolerance to be considered "in range",
  • 100.0 represents the new setpoint in Kelvin for the second heating loop,
  • 1.5 represents the tolerance in Kelvin for the second heating loop,
  • 30 represents the time that the second temperature needs to stay within the tolerance to be considered "in range".

• Setting the Cryostat Temperature (1-loop mode):

  SET Temperature 100.0 1.0 60
  

  where:
  • Temperature represents the alias for the temperature controller frontend,
  • 100.0 represents the new setpoint in Kelvin,
  • 1.0 represents the tolerance in Kelvin,
  • 60 represents the time that thetemperature needs to stay within the tolerance to be considered "in range".

• Setting an helium flow:

  SET Flow FLOW 2.5
  

  where:
  • Flow represents the alias for the flow controller frontend,
  • FLOW represents the parameter to be changed,
  • 2.5 represents the flow in l/min.

• Setting a magnet:

  SET Magnet WED 1000 60
  

  where:
  • Magnet represents the alias for the magnet controller frontend,
  • WED represents the name of a specific magnet,
  • 1000 represents the new field in Gauss,
  • 60 represents the waiting time for the field stbilization.

• Setting a sample rotation angle:

  SET Position ANGLE 130.0
  

  where:
  • Position represents the alias for the rotation controller frontend,
  • ANGLE represents the parameter to be changed,
  • 130.0 represents the new angle.

• Setting a new value for the Tube Heater:

  SET Tube_Heater I 0.230
  

  where:
  • Tube_Heater represents the alias for the Tube Heater frontend,
  • I represents the parameter to be changed (here the current),
  • 0.230 represents the new current in Ampere.

• Setting a new value for a beamline element:

  SET Beamline_PiM3 FS302 400
  

  where:
  • Beamline_PiM3 represents the alias for the Beamline Controller frontend,
  • FS302 represents the element to be changed (here the slits in front of GPS),
  • 400 represents the new DAC value for this element.
