Start controller with Loaded module - LoadModuleFromFile function was used.

EugeneB

Hi everyone,
How can I start the controller with the loaded module inside? I'm using pc sdk application. Using LoadModuleFromFile function and now I would like to start the controller. How can I trigger the execution of that module?

Thank you?

Hello Eugene,

after loading the module you have to set the program pointer to a routine:

For routine "main" you can use the method "ResetProgramPointer", see:
http://developercenter.robotstudio.com/blobproxy/devcenter/RobotCommunication/html/e73d2cb4-1974-f850-471f-52abe9951166.htm

For another routine, you have to use the method "SetProgramPointer", see
http://developercenter.robotstudio.com/blobproxy/devcenter/RobotCommunication/html/edd35108-78a7-01de-a154-186d03d0226d.htm

Afterward, you have to "Start" the program, see
http://developercenter.robotstudio.com/blobproxy/devcenter/RobotCommunication/html/4dc4d703-0b11-363a-31bf-674cacd97b5e.htm

Please have also a look into the manual "Working with RAPID modules and programs"
http://developercenter.robotstudio.com/blobproxy/devcenter/RobotCommunication/html/847d1dda-5ab5-4fec-a238-9e5d34115938.htm

I hope I could help you.

Thanks Micky,
I have one more question. I load the module from external hard drive, set program pointer to sequence routine inside that module, finished running that module. The controller will continue to go through that module over and over, right? How can I stop the controller at the end of my module/sequence, resave that module back to my external hard drive and delete that module? I know the delete method is exist, but I need to re-save that module back to the external hard drive. Basically same procedure as from the production manager but only from my application and with external/network hard drive (not from the controller ).

Thanks for your help,
Eugene

Hello Eugene,

you could stop the program as follows:

1. Starting the cycle once with the following method: 

   task.Start(RegainMode.Continue,ExecutionMode.Continuous,ExecutionCycle.Once)

   (See http://developercenter.robotstudio.com/blobproxy/devcenter/RobotCommunication/html/d53ae203-12ad-821c-f1e9-54a8f1886bf4.htm)
   
   
2. or add the instruction "Stop" or "Exit" at the end of your RAPID routine

Observe the execution state and as soon as the program stops you save and delete the module.

...
//Load module 
//start robot program
aController.Rapid.ExecutionStatusChanged += ExecutionStatusChanged;
..

private void ExecutionStatusChanged(object sender, ExecutionStatusChangedEventArgs e)
{
   if (e.Status == ExecutionStatus.Stopped)
   {
       aController.Rapid.ExecutionStatusChanged -= ExecutionStatusChanged;
       //Save module
       //Delete module
   }
}

In case it not possible to save the module directly on your computer, you have to save it first onto the controller (maybe in the TEMP directory) and copy it later to your PC.

How can I copy it from the controller (temp folder)? What kind of method should I use?

EugeneB

You included the link for the file system domain. 
Thank you Micky for all your help.

Hello Eugene,

Maybe you should set an additional signal or a persistent at the end of the program so that you know for sure that the program has really quit and not just stopped. 

If only the program stop is monitored, your PC program will delete the current robot module and the robot can no longer continue its program.

This means that in addition to the program stop you would also have to check the current value of the persistent or the signal and only then save and delete the module if this is the case.

Hi Micky,
Yes, you right. And I can set something like:
pseudocode:
public void .... (objec sender, Signal state change)
 {
    Save module;
    Copy module;
    Delete module;
 }
