How to Find the Advantech’s VIs from LabVIEW Environment(1) Make sure that the Active Windows is in Diagram mode, Windows Show Diagram (Ctrl +

E)

(2) Eanble the Functions Palette dialog, Windows Show Functions Palette

(3) Click on the Advantech icon, you will find that the Advantech LabVIEW driver is divided by two main group: Easy I/O VIs and Advanced I/O VIs. For detail usage on the suppoted VIs, please refer to Advantech LabVIEW Driver User’s Guide.

Start from Tutorial Example

Tutorial 1: Get voltage input from PCL-818L(C:\Program Files\National Instruments\labVIEW\Examples\Examples\Advantech\TUTOR1.VI)

(1) Click on New VI button to create a new LabVIEW program.

(2) Select Front Panel and enable Controls Palette to choose a Waveform Chart indicator in Graph group, add it to front panel and named it Voltage.

(3) Switch to Block Diagram to verify that a new data terminal was created (named Voltage).

(4) Add a DeviceOpen VI from the Advantech 32-bit LabVIEW driver by clicking on Advantech VIs. The path to get DeviceOpen VI is Advantech >> Advance >> DeviceManager >> DeviceOpen.

(5) Move the mouse to the DeviceOpen VI and click on the mouse left button to invoke the Create Constant function. After creating a constant, a number will appear at the left of DeviceOpen VI block. Change the value of the constant next to the “DeviceOpen” VI to be 1.

(6) Execute the Advantech device installation utility (within Advantech DLL driver) from the Windows environment to check with the device number of Advantech DEMO I/O virtual demo board. For example, the device number of Advantech DEMO I/O in the screen shown below is 001.

(7) Add AIConfig and AIVoltageIn, and then change the mouse cursor for use with the Wiring pattern (move the cursor into Tools Palette and select the Wiring icon) to establish the linkage. The path to get AIConfig and AIVoltageIn VI is Advantech >> Advance >> adSlowAI >> AIConfig and AIVoltageIn. The Help window shows input and output parameters of each selected VI. (The way to display the Help window is to click on the Help menu selection and select the “Show Help” option)

(8) Add DeviceClose VI, and then establish the linkage.. The path to get DeviceClose” VI is Advantech >> Advance >> DeviceManager >> DeviceClose.

(9) For the AIConfig VI, Channel and Gain are necessary input values. In order to provide Channel and Gain values for the AIConfig VI, you can add two controls items in Front Panel and pass their values to the AIConfig VI in Block Diagram.

(10)Create the linkage to show the AI signal to Waveform Chart.

(11)The basic steps to get AIVoltageIn data are now complete. You can switch to the window to the Front Panel window and click the Run button to execute AIVoltageIn VI.

(12)If your waveform chart does not show the whole graph, you can change the scale of the Y-axis. To change the Y axis scale on the waveform chart, move the cursor to the graphic origin, click the left mouse button, and type in the desired value.

(13)You can also add a “While Loop” to enhance your program. First, move mouse to Functions Palette and select the Structures group and the While Loop VI. Add the While Loop VI to the Block Diagram and enlarge it to include the AIVoltageIn VI and the Voltage data

terminal.

(14)Add a Stop button to control the execution of the While Loop. Enable the Front Panel and move the mouse to Controls Palette. Select the Boolean and Rectangular Stop Button to add a STOP button to the Front Panel.

(15)Switch to Block Diagram. A TF VI should be showing on the Diagram. Move the TF VI into the While Loop VI and add a NOT VI from Functions Palette. Move NOT VI to the location between TF VI and COND VI. Wire the output of the TF VI to the input of the NOT VI and wire the output of the NOT VI to the input of the COND VI. After wiring, switch to Front Panel and press the RUN button to execute.

(16)If you want to get voltage data from a given device, just change the constant number of the DeviceOpen VI to be the device number of the device of interest. For example, the device number of the PCL-812PG in this tutorial is 0.

How to create a new CIN block to call to Advantech 32-bit DLL Driver

CIN Overview:The LabVIEW Code Interface Node (CIN) supplies a way for user to link external code

written in a conventional programming language to LabVIEW. A CIN is a block diagram node associated with a section of source code written in a

conventional programming language. You may compile the source code first and link it to form executable code. LabVIEW calls the executable code when the node executes, passing input data from the block diagram to the executable code, and returning data from the executable code to the block diagram.

Steps for Creating a CIN code under Windows 951) Place the CIN block on a Block Diagram

2) Add Input and Output Terminals to the CIN. Press right mouse key and select “Add Parameter” for each raw (Left is the Input or Initial value, left is the Output)

3) Presses right mouse key and select Create .c File item and modify the code inside. Please take care of those codes,

/* * CIN source file */

/* Source CIN of adManager.llb\DeviceOpen.vi */#include <extcode.h>#include <hosttype.h>#include <windows.h>#include "driver.h"

/* stubs for advanced CIN functions */

CIN MgErr CINRun(uInt32 *DevNum, uInt32 *DevHandle, TDSTA *ErrInfo){ int len; char msg[256], buf[100]; MgErr Err;

ErrInfo->Code = DRV_DeviceOpen(*DevNum, DevHandle); if(ErrInfo->Code) { ErrInfo->Status = LVTRUE;

/* Get Error Message */ StrCpy(msg, "DeviceOpen.vi : "); DRV_GetErrorMessage(ErrInfo->Code, buf); StrCat(msg, buf);

len = StrLen(msg)+1; if(Err=NumericArrayResize(uB, 1L, (UHandle *)&(ErrInfo->Source), len)) return Err; LStrLen(*(ErrInfo->Source)) = len; StrCpy(LStrBuf(*(ErrInfo->Source)), msg); } else { ErrInfo->Status = LVFALSE; } return noErr;}

4) Set up the compiler environment (under DOS Prompt Windows). Please run below line to set up the compiler environment. Here C:\VC5.0\DEVSTUDIO\VC\BIN\ is the directory of VC compiler.

@echo offCALL��C:\vc5.0\devstudio\vc\BIN\VCVARS32��x86

5) Compiler the source codes. Create a .LSB file, Devopen.LSB, to be linked to a CIN block in Labview environment latter.

Nmake��/f��Devopen.lvm > c.err

Below is the content of Devopen.lvm. Here the filename, Devopen.lvm, could be a user defined filename. If you want to use standard C or Windows 95 or Windows NT libraries, define the symbol cinLibraries in a .LVM. The file, ADSAPI32.LIB, is the header library of C:\WINDOWS\ADSAPI32.DLL.

Trouble Shooting Q: Why cannot I use QConter feature on the PCL-836 card?

A: Sorry, there is no 3-axis Quadrature Encoder feature on PCL-836, only PCL-833 card supports those features. Please also refer to the Table 4-1. DLL Functions on Advantech LabVIEW Driver User’s Guide. For those supported functions, Table 4-1. DLL Functions shows detail information on it. Because the Advantech 32-bit DLL driver supply an interface to call to the Advantech 32-bit DLL driver, for more information about how to setup each parameter, you can also refer to the Advantech 32-bit DLL driver for Windows NT/95 Ver. 1.00 for relative information.

Q: Why cannot I setup the pulse width of output pluse on the PCL-818 serial cards?A: Sorry, only PCL-836 card supports this function.

Q: Although I have enabled the Alarm function through ADAM utility, I cannot use the Alarm function when I try on the Alarm.VI.A: To use the Alarm function, you should enable the Alarm function from the setup in Device Installation utility.

Q: I cannot use the LabVIEW driver after I install the Advantech LabVIEW driver into my system.A: Please make sure that you have installed the Advantech LabVIEW driver into the same directory where you install the LabVIEW software, \Program Files\National Instruments\LabVIEW\.

Q: I cannot use the Analog Output with DMA on PCL-1800 and PCL-816.A: Please check with the Hardware User’s Manual on these two cards, the Analog Output channel with DMA transfer is Channel 1 for PCL-1800, and Channel 0 for PCL-816.

Q: Could you please inform us detail information on the Watchdog feature of PCL-1800 card.A: ???

Q: How can I perform Direct I/O function and receive Interrupt Event through LabVIEW driver.A: Please refer to the example, PORTIO.VI and FDIGIT.VI.

Q: How can I use the Advantech LabVIEW driver to communicate with PLC device through COM port.A: Please refer to the example, COMMPORT.VI, which can send up to 256 characters on each time you send command string to COM port.

Q: How can I implement my own CIN block to call to Advantech 32-bit DLL driver.A: Please refer to the following topic in this document,
