3. Each Sub VI contains the required references to the software console so additional programming is not required LabVIEW NEXYGEN Interface Driver Features Ease of uSe programming via pictures Logical and intuitive for current users of LabVIEW Includes 15 Sub VI s for programming tests Predefined example programs are provided in the manual which can be easily modified 3 software consoles are provided for controlling different machines ISO TickIT Accreditation NEXYGEN By double clicking on any Sub VI a VI schematic diagram will be revealed which is summarised by the block diagram Example Control Sub VI Console In Console Out Control VI Schematic Diagram Console In a Console Lut F H espgenlabiiewLtl P n 20 gt ee The user need never see the schematic diagram unless he wishes to alter the machine operation or program a testing sequence from scratch Creating a Test Program Using the Sub VI s is Easy and Logical Example Pull to Limit Test Step 1 The User Interface Within the User Interface right click the mouse to display the CONTROL palette shown below and select the Numeric Icon Choose the Gauge option and label the Gauge Load Do the same again and label the second Gauge Extension r Controls Step 1 Numeric Step 2 The Programming Interface Load and Extension are now also shown on the Programming Interface To develop the rest of the program right click the mouse for the FUNCTI
4. programme a test with the LabVIEW NEXYGEN Interface Driver the user has the option of using predefined test procedures Sub VI s which they may modify or alternatively create their own test procedure from sctratch The interface driver provides 15 Sub VI s Virtual Instrument s that can be strung together to form a programme to perform a test SUB VI FUNCTION Break End the Stage or StageHold when the Load falls BY X of Max Load BreakS harp End the Stage or StageHold when the Load quickly falls to zero Compression Select Compression Mode Connect Creates the Console Object and connects it to the machine Control Allow the Software Console to Move the Machine Error Report any errors from the Software Console Quit Closes the Software Console Readings Reports the Last Load and Last Extension Reading ReleaseConsole Releases the Console Object ReturnToZero Moves the Machine to its Zero Positon Stage Moves the Machine to the specified Limit at the Specified Speed StageHold Moves and Holds the Machine at the specified Limit for the Specified Time Tension Select Tension Mode Values Reports ALL the Load and Extension Readings since it was last Run Zero Sets the Machines Zero Position and sets the Load Reading to Zero Sub VI s are summarised schematic diagrams which have been pre programmed for you Sub VI s cannot be used independantly but when placed on the diagram and wired together they make a valid and logical test sequence
