You can use the CXA_PYTHON library:

Or use the REST API of the Data Layer with standart CXA_Datalayer

[Fred74]

What should I copy inside those 2 following inputs :

-Instance Name 

- File Name 

PS : I use your "DevelopR" example

Here a working example:

VAR
	fbIL_ScriptInstance: IL_ScriptInstance;
	StateInstance: CXA_PYTHON.INSTANCE_STATE;
	bEnableInstance: BOOL;
	bInOperationInstance: BOOL;
	bErrorInstance: BOOL;
	ErrorIDInstance: CXA_PYTHON.ERROR_CODE;
	ErrorIdentInstance: CXA_PYTHON.ERROR_STRUCT;
	strInstanceName: STRING := 'MyTestInstance'; //Name of script instance to be created
	bResetInstance: BOOL;
	bAbortScript: BOOL;
	
	fbIL_StartScriptFile: IL_StartScriptFile;
	bExecuteFile: BOOL;
	bDoneFile: BOOL;
	bActiveFile: BOOL;
	bErrorFile: BOOL;
	ErrorIDFile: CXA_PYTHON.ERROR_CODE;
	ErrorIdentFile: CXA_PYTHON.ERROR_STRUCT;
	strFilePath: STRING(255) := 'activeConfiguration/test.py'; //Path to the file to be executed e.g. root folder of the active configuration
	ParametersFile: ARRAY [0..9] OF STRING;
END_VAR

fbIL_ScriptInstance(
	Enable:= bEnableInstance, 
	InOperation=> bInOperationInstance, 
	Error=> bErrorInstance, 
	ErrorID=> ErrorIDInstance, 
	ErrorIdent=> ErrorIdentInstance, 
	InstanceName:= strInstanceName, 
	ResetInstance:= bResetInstance, 
	AbortScript:= bAbortScript, 
	State=> StateInstance);
	
fbIL_StartScriptFile(
	Execute:= bExecuteFile, 
	Done=> bDoneFile, 
	Active=> bActiveFile, 
	Error=> bErrorFile, 
	ErrorID=> ErrorIDFile, 
	ErrorIdent=> ErrorIdentFile, 
	InstanceName:= strInstanceName, 
	FileName:= strFilePath, 
	Parameters:= ParametersFile);

This is not very clearly explained in the IDE manual (R911410625, Edition 02, image below). When deploying to the target it would appear that the file path is 

/skripts/Bosch/TIGER/application.py when in reality the path that works is /activeConfiguration/scripts/bosch/tiger/application.py

[CodeShepherd]

The path changed during development and is now always the active configuration for all our our apps. This has to be changed in the documentation thanks for mentioning.

Hello,

I have been trying to Start the IDE Project in the PLC application but every time I execute the StartScriptFile FB the StateInstance changes to "Error" and the ctrlX Core returns a 081F2001 Error. It seems that the EnableInstance FB creates successfully the instance, as I can see it in the Datalayer but every time I start the script it returns this error,

Attached the pictures,

Does anyone know why is this happening?

Thanks for the help,

Look at C0270302. Looks like maybe there is a script error. 

Script runner could not execute the script

Cause/Remedy 1: Cause: The script interpreter has detected errors in the script. Remedy: Correct your script file.
