DragScript Flow of Control

From Voyager Wiki
Jump to navigation Jump to search

These DragScript elements control the flow of execution through your script. You can use the DragScript Simulator to test how control will flow when the DragScript actions complete with OK, ERROR or TIMEOUT status, and when Emergency Suspend, Resume and Exit events happen.

Variables

DragScript has several variable types: counters (integers), string variables and decimal numbers. They must be declared with the Counter, String or Decimal Number actions before they can be used. You can set and change their values, and then make decisions to execute DragScript actions based on their value. For example, you may build a script that runs from zero to ten sequences based on the value of a counter variable you set at the start of the script.

Jumps

Jumps are used to goto a specified block of the DragScript. You can jump to the Start, End or a named Block.

Dragscript-jumps.png

  • Goto End: Jump to the End block of the script


Repeats

Repeats are used to execute a DragScript block a specified number of times, or until a specific time, or until astronomical night ends.

Repeats must be placed inside a block (note: Script: is a special block that contains the entire script.

If the result of evaluating a Repeat is to repeat the block, control returns to the block statement that contains the repeat.

Dragscript-repeats.png

  • Repeat Block for n Times: Repeat the containing block a specified number of times

Dragscript-repeat-block.png

  • Times: Number of times to repeat this block
  • OK: Save changes and close the window
  • Cancel: Discard changes and close the window
  • Repeat Current Block Until Time: Repeat the contained block until the specified time:

Dragscript-until-time.png

  • Time: Repeat the current block until this time
  • OK: Save changes and close the window
  • Cancel: Discard changes and close the window
  • Repeat Block Until Astronomical/Nautical/Civil Night End:

Dragscript-repeat-until-night-end.png

  • Get Latitude and Longitude from Mount: Retrieve the current latitude and longitude from the connected mount, which must support this command. This location is used, along with the current date, to determine the time that astronomical/nautical/civil night ends
  • Use the Latitude and Longitude indicated below: Specify your current latitude and longitude in the fields below. This location is used, along with the current date, to determine the time that astronomical/nautical/civil night ends
  • Offset: Time in HH MM SS
    • Offset Before: If selected, repeat the block until this amount of time before astronomical/nautical/civil night ends
    • Offset After: If selected, repeat the block this amount of time after astronomical/nautical/civil night ends
  • Default: Use the default settings
  • OK: Save changes and close the window
  • Cancel: Discard changes and close the window


Important Note! The time will be considered to have been reached if it is within 12 hours of the current time when the check is performed. E.g., if we set a repeat until 05:00, if it is 23:30 the repeat will be done since 23:30 is more than 12 hours in the future and less than 12 hours in the past, relative to 05:00. If it is 11:00, the repeat will be skipped, since 11:00 is later than 05:00 and more than 12 hours in the past.


Decisions

Decisions control the flow of your DragScript based on the results of an action (OK, ERROR, TIMEOUT), operating conditions (current time, date or target altitude), or the value of a variable.

Important Note! A Decision element will create a new indent level in your DragScript. Drag new elements and drop them on the Decision element, or copy and paste them to it, to have their execution controlled by the result of the Decision

Events

DragScript execution can be suspended, terminated (exited) and resumed based on the occurrence of Emergency Exit, Emergency Suspend and Emergency Resume events.

The most common use of Events is together with a weather monitoring system, as configured in Weather Setup. You can specify at a detailed level which events should cause DragScript execution to SUSPEND (such as overcast clouds), EXIT (such as rain), or RESUME (such as clouds moving out so it becomes clear again).

In addition to weather events, you can raise Emergency Exit, Emergency Suspend and Emergency Resume events at any point in your DragScript.

When an Event is raised, control flow goes immediately to the appropriate block (Exit, Suspend or Resume) in the Events block of your DragScript. Create those blocks by dragging elements from the Events: Manage list.

Dragscript-events.png

Manage

See the DragScript Examples section to see how these blocks work in a DragScript.

  • Emergency Exit: Drag this element to the Events block of your DragScript. Then drag the actions you wish to take place when an Emergency Exit event is raised. For example, stop tracking, stop guiding, park your mount, and close the observatory roof
  • Emergency Suspend: Drag this element to the Events block of your DragScript. Then drag the actions you wish to take place when an Emergency Suspend event is raised. For example, stop tracking and stop guiding

  • On Resume Timeout Restart DragScript: If the time specified above is reached without an Emergency Resume event occurring, Voyager will restart the DragScript form beginneng like a new running
  • OK: Save changes and close the window
  • Cancel: Discard changes and close the window


  • Emergency Resume: Execute these actions when an Emergency Resume event is raised. For example, start tracking and start guiding

Raise

Raise an Emergency Exit, Suspend or Resume event

  • Raise Emergency Exit Event: Raise the Emergency Exit event. Execution of the DragScript will go immediately to the Emergency Exit block in the Events block
  • Raise Emergency Suspend Event: Raise the Emergency Suspend event. Execution of the DragScript will go immediately to the Emergency Suspend block in the Events block
  • Raise Emergency Resume Event: Raise the Emergency Resume event. Execution of the DragScript will go immediately to the Emergency Resume block in the Events block

Remote

Block for management of Distributed Distributed Emergency

  • Set Distributed Emergency Status: Update overriding the internal Distributed Emergency Status for the Voyager Client connected to the selected value
    • Des1.png
  • Distributed Safe: Distributed Safe wait the night like configured and in the night wait to have a Safe condition from the Emergency Event System (in Voyager is Weather, Safety Monitor, Viking I/O). If night is recognized and safe condition is true DragScript will exit from this block with OK result. If timeout is reached waiting DragScript will exit from this block with a TIMEOUT result. In case of error during waiting DragScript will exit with ERROR result. Checking the exit of block user can decide if inform all the client of a SAFE condition using the SET DISTRIBUTED EMERGENCY STATUS or restart the Master DragScript to wait for better conditions (same night or next night is automatically decided from DragScript). This block is usually associated and work only if you using the Distributed Emergency plugin. Right and only place where to use is the Voyager MASTER of plugin where information is processed and emergency events checked.
    • Important Note! Distributed Safe Cannot be used inside the Event Manager (Exit, Suspend, Resume)
      • DES2.png
      • NIGHT Configuration: data necessary to calculate the start and end interval of the actual night
        • Night DATA: data about location of observatory
          • Latitude: Latitude of the Mount
          • Longitude: Longitude of the Mount
        • Night TYPE: type of night to calculate. Astronomical, Nautical or Civil
        • Night START OFFSET: apply an offset to the time start of the night
          • Offset Before: offset before the start in hours, minutes and seconds
          • Offset After: offset after the start in hours, minutes and seconds
        • Night END OFFSET: apply an offset to the time end of the night
          • Offset Before: offset before the end in hours, minutes and seconds
          • Offset After: offset after the end in hours, minutes and seconds
        • EVENT CHECK options: with this option you can decide to remove from processing status of SAFE some kind of events that will be ignored (event in any case are disable during the wait safe action)
          • Check Emergency Exit Status in SAFE status calculation: if unchecked the condition that throw an Emergency Status will be ignored in calculation of SAFE Staus . ATTENTION !! this is a way really dangerous for your setup .. use only if you want to wait safe in particular condition , particular timing and for particular tasks
          • Check Emergency SUSPEND Status in SAFE status calculation: if unchecked the condition that throw an Emergency Status will be ignored in calculation of SAFE Staus . ATTENTION !! this could be a way really dangerous for your setup .. use only if you want to wait safe in particular condition , particular timing and for particular tasks.
        • LIGHT CONDITIONS options: with this option you can decide to remove from processing status of SAFE the LIGHT Conditions status
          • Remove Weather LIGHT Conditions Status From Calculation of All Emergency Status: if unchecked the LIGHT conditions from Weather system will be not used to calculate the SAFE Status. Usefull if you want to open the dome with the light approaching the night time and do skyflat. For the Dawn flat you can decide to disable the LIGHT event using dedicated block
        • Default: Use the default settings
        • OK: Save changes and close the window
        • Cancel: Discard changes and close the window

Various

  • Resume from Block: Resume execution starting with the specified block. This can only be placed in the Emergency Resume block in the Events block

  • Block: Choose the block where execution should resume from the drop-down list
  • OK: Save changes and close the window
  • Cancel: Discard changes and close the window


  • Disable Events: Disable event processing. Emergency Exit, Suspend and Resume events will be ignored
  • Enable Events: Enable event processing. Emergency Exit, Suspend and Resume events will be recognized and handled
  • Disable Exit Event: Disable event processing. Emergency Exit only event will be ignored
  • Enable Exit Event: Enable event processing. Emergency Exit event will be recognized and handled
  • Disable Suspend Event: Disable event processing. Emergency Suspend and Resume only events will be ignored
  • Enable Suspend Event: Enable event processing. Emergency Suspend and Resume only events will be recognized and handled
  • Disable Weather Light Event: Disable event processing of Light conditions coming from Weather System. Status of Light will be not used to processing the Emergency Exit and/or Emergency Suspend or Emergency Resume events (Work only if you have a weather system configured in Voyager)
  • Enable Weather Light Event: Enable event processing of Light conditions coming from Weather System. Status of Light will be used to processing the Emergency Exit and/or Emergency Suspend or Emergency Resume events (Work only if you have a weather system configured in Voyager)


Important Note! Enable and disable Events is a really powerful features !!! Please use with complete understand that if you forget to re-enable the events your setup can be damaged from weather conditions.


Important Note! Enable and disable Light Conditions from emergency status calculation can be useful for do SkyFlat or generally other kind of tasks at dawn and dusk or for daylight operations and testing.


Events Robotarget

If you are running a Voyager Advanced or Full version you can intercept the thrown events generated by RoboTarget Action during. This event can be annotations or errors. Data about are saved in the environment variables of DragScript and can be used in the signal block of DragScript. What is inside the Events RoboTarget Management will executed in seld contained DragScript ineriths by the actual DragScript eliminating all except what is in the events handle you have created.

To select the event handle and create it you must use the Operating Conditions blocks.

Operating Conditions

There is only one operating conditions block to handle a RoboTarget Event. The DO IF ROBOTARGER EVENT. You can use one or more of this block.

  • DO IF ROBOTARGER EVENT: Handle one or more events related to RoboTarget Action executing in a self contained ineriths dragscript the block inside the condition
  • Immaginergerwerhgwrh.png
  • Even(s) Selected: select one or more RoboTarget events to handle
  • Reset: Uncheck all the events selected and remove from handling
  • Cancel: exit from configuration without save anything
  • OK: Save changes and close the window

Block

The Block element creates a new block in your DragScript. Drag and Drop it on a DragScript element that creates a new indent level, e.g. Script, DO IF, IF, Emergency Exit, Emergency Suspend, or Emergency Resume.

  • Label: Give your block a name. This name can be referenced by other script elements such as jumps and resumes
  • OK: Save changes and close the window
  • Cancel: Discard changes and close the window


Remark

The Remark element adds a non-executable comment to your script for documentation purposes

  • Remark: Enter a comment that will appear in your script
  • OK: Save changes and close the window
  • Cancel: Discard changes and close the window


Flow

Flow Control are useful for changin flow of execution during DragScript

  • Exit Block: exit the current block container and execute the first following useful instruction
    • must be used inside a BLOCK container
    • cannot be used directly under the SCRIPT default block or EVENTS default block
    • if nested inside more than one BLOCK container DragScript Engine will exit from the first BLOCK container parent
  • Restart DragScript: The Restart DragScript element allow script to be restart from beginning, all the variable and status will be resetted
