Detailed Description

These commands act on Sample Enviroment labVIEW VIs directly and do not use the blocks configured in SECI and displayed on the dashboard like the high level commands.

They are usually used to produce custom commands where more complexity than is allowed by e.g. CSET() is needed.

CALLLABVIEW	(	String	VI,
		String	NAME1,
		Var	VALUE1,
		String	NAME2,
		Var	VALUE2,
		String	HOST
	)

Call a LabVIEW VI as a Sub VI.

This command is passed the name of the LabVIEW VI to call and a set of (name, value) parameters. It will call the VI and not return until processing is complete.

Parameters:

[in]	VI	Name of VI to call
[in]	NAME1	Label of Variable on VI front panel
[in]	VALUE1	Value of Variable on VI front panel
[in]	NAME2	Label of Variable on VI front panel
[in]	VALUE2	Value of Variable on VI front panel
[in]	HOST	(optional) Remote HOST to connect to (default: as specified by ISC_SETUP)

Returns:

VI call result

SETLABVIEWVAR()

GETLABVIEWVAR	(	String	VI,
		String	VARNAME,
		String	HOST
	)

Read a variable from a LabVIEW VI.

This command is passed the name of the LabVIEW VI and the label for the variable on the front panel.It will return the value of that variable.

Parameters:

[in]	VI	Name of VI to read
[in]	VARNAME	Label of Variable on VI front panel
[in]	HOST	(optional) Remote HOST to connect to (default: as specified by ISC_SETUP)

Returns:

Value of VI control/indicator

SETLABVIEWVAR()

Example:

VAL=GetLabVIEWVar("Eurothem.vi", "Some Control label") 

LOADSCRIPT	(	String	SCRIPT,
		String	DIR
	)

Load a script file into memory and name it.

This loads a script file, whihc has a .isc extension and is like a GENIE PROCEDURE except that is is missing the PROCEDURE and ENDPROCEDURE commands. The file is loaded and a command is defined in GENIE whihc is the same as the filename; this name can then be used to execute the script.

Parameters:

[in]	SCRIPT	name of script to run
[in]	DIR	(not used at present)

PUSHLABVIEWBUTTON	(	Qualifier	WAIT,
		String	VI,
		String	BUTTONNAME,
		String	HOST
	)

Push a button on a LabVIEW VI.

This command is passed the name of the LabVIEW VI and the label for the button. It will press the button and (optionally) wait for the button to pop back up again.

Parameters:

[in]	VI	name of LabVIEW VI
[in]	BUTTONNAME	label of Button on VI
[in]	HOST	(optional) name of computer to connect to (default: That specified by ISC_SETUP)
[in]	WAIT	Wait for button to pop back up before returning from procedure (default: NOWAIT)

See also:

SETLABVIEWVAR()

Example:

PushLabVIEWButton "Eurothem.vi" "Read Value" 

SETLABVIEWVAR	(	String	VI,
		String	VARNAME,
		Var	VALUE,
		String	HOST
	)

Set a variable on a LabVIEW VI front panel.

This command is passed the name of the LabVIEW VI and the label for the variable on the front panel. It will set the variable to the supplied value.

Parameters:

[in]	VI	Name of VI to read
[in]	VARNAME	Label of Variable on VI front panel
[in]	VALUE	Value to set
[in]	HOST	(optional) Remote HOST to connect to (default: as specified by ISC_SETUP)

GETLABVIEWVAR()

Example:

SetLabVIEWVar "Eurother.vi" "Temperature" 55.0 

WAITFORBOOLEAN	(	Qualifier	FALSE,
		Qualifier	TRUE,
		String	VI,
		String	BOOL,
		String	HOST
	)

Wait for a Labview VI boolean variable to become either true or false.

This command is passed the name of the LabVIEW VI to call and a set of (name, value) parameters. It will call the VI and not return until processing is complete.

Parameters:

[in]	VI	name of labview VI
[in]	BOOL	label for boolean variable
[in]	TRUE	wait for value to become TRUE
[in]	FALSE	wait for value to become FALSE (default: TRUE)
[in]	HOST	(optional) Remote HOST to connect to (default: as specified by ISC_SETUP)

WAITFORBUTTON()

WAITFORBUTTON	(	String	VI,
		String	BUTTON,
		String	HOST
	)

Wait for a Labview VI button to pop back up.

This command is passed the name of the LabVIEW VI to call and a set of (name, value) parameters. It will call the VI and not return until processing is complete.

Parameters:

[in]	VI	name of labview VI
[in]	BUTTON	label for button
[in]	HOST	(optional) Remote HOST to connect to (default: as specified by ISC_SETUP)
