0, //Resistance offset 0, //Voltage Offset ARI32XXFrequencyEnum::ARI32XXFrequency60Hz );

//Frequency for AC ouput Mode

//Add GND step and then edit parameters driver->Steps->AddGNDTestWithDefaults(); driver->Parameters->OutputMode = ARI32XXTestModeEnum::ARI32XXTestModeDC; driver->Parameters->Dwell = 5; driver->Parameters->Current = 20; driver->Parameters->Voltage = 5; driver->Parameters->HighLimit = 200; driver->Parameters->LowLimit = 0; driver->Parameters->HighLimitVoltage = 6; driver->Parameters->LowLimitVoltage = 0; driver->Parameters->Offset = 10; driver->Parameters->OffsetVoltage = 0.2; //driver->Parameters->Frequency = ARI32XXFrequencyEnum::ARI32XXFrequency50Hz; //DC do not support frequency configuration

driver->Files->Save();

For the HYAMP 4, all of the test parameters would be within a file. Therefore, you need to create a file first and then select a file to be edited. For the previous firmware version, it does not support the methods of AddGNDTest(). Therefore, we could add the steps with default values using the AddGNDTestWithDeafults() and then modify the parameters. At first, there is a try-catch process to handle creating files with the name might be existed.

3.3 Load file and start a test
//Output driver->Execution->Execute();
Before running output, you have to select a file to load using driver->files->Load(). And then invoke driver->Execution->Execute() method to start a test.

3.4 Measure during test
bool lastOpcStatus = false; while (true) {
std::cout << driver->Execution->ReadTestDisplayRaw() << std::endl; driver->System->WriteString(“*OPC?n”); std::string opcStatus = driver->System->ReadString(); if (opcStatus.find(“1”) != std::string::npos && lastOpcStatus)
break; lastOpcStatus = opcStatus.find(“1”) != std::string::npos; Sleep(100); }
This while loop would run with the condition of state is testing. Using the methods of
Execution.ReadTestDisplayRaw() could let you read the immediate readings.

Development
1 Install the Comtypes library pip install cometypes
In order to call an external com DLL in Python, you will need comtypes library installed.
2 Create a Python file 2.1 Open any IDE of Python and create a new Python file.
3 Import Libraries 3.1 Import the cometypes library and ARI32XX_64.dll
import time import comtypes import comtypes.client as cc

Import the IVI-COM DLL cc.GetModule(‘ARI32XX_64.dll’) from comtypes.gen

import ARI32XXLib
4 Start programming 4.1 Create an object of the driver and use the initialize method to build up the connection.
driver = cc.CreateObject(‘ARI32XX.ARI32XX’, interface=ARI32XXLib.IARI32XX) # Initialize Driver and make connection driver.Initialize(‘ASRL7::INSTR’, True, False, ‘DriverSetup=BaudRate=38400’)
For more detail for the parameters of the Initialize() method, please refer to the help document, ARI32XX.chm located at “IVI FoundationIVIDriversARI32XX”. The first parameter ResourceName is a string type and indicates the interfaces type and address of the connection. The resource name,”ASRL7::INSTR”, represents a serial port with address 7. For example, a GPIB connection could be “GPIB0::8::INSTR”. For TCP/IP connection, it will be in the format of “TCPIP0::192.168.0.1::10001::SOCKET”. The 10001 is the TCP/IP connection port of HYAMP 4. The second argument should be set with false value for not identifying the model names. It is a known issue that the HYAMP 4 returns the incorrect format of string which cause the model could not be detected correctly. If you use serial port to connect to device, please follow the above example, “DriverSetup=BaudRate=38400”, to setup the baud rate. There are other parameters for the option of the Initialize() method, please refer to the ARI32XX.chm for more detail. For example, “QueryInstrStatus=true” makes the session automatically query the error status for each command was sent.
4.2 Create file and setup test

Create file try:

driver.Files.Create(1, “IviTest”) except:
28105 N. Keith Drive Lake Forest, IL 60045 USA Toll Free: 1-800-858-TEST (8378) US/Canada Phone: 1-847-367-4077 | Fax: 1-847-367-4080 | www.arisafety.com

files = driver.Files.TotalFiles; for i in range(1,files+1):
if ‘IviTest’ in driver.Files.QueryFileName(i): driver.Files.Delete(i) driver.Files.Create(i, ‘IviTest’) break

Add ground bond test item by AddGNDTest() driver.Steps.AddGNDTest(

ARI32XXLib.ARI32XXTestModeAC, #Output Mode 1, #Dwell Time 25, #Current 8,

Voltage 0, #Resistance High Limitation 0, #Resistance Low Limitation 0,

Voltage High Limitation 0, #Voltage Low Limitation 0, #Resistance offset 0,

Voltage Offset ARI32XXLib.ARI32XXFrequency60Hz #Frequency for AC ouput Mode

);

Add an GND step and then edit parameters

driver.Steps.AddGNDTestWithDefaults(); driver.Parameters.OutputMode = ARI32XXLib.ARI32XXTestModeDC; driver.Parameters.Dwell = 5; driver.Parameters.Current = 20; driver.Parameters.Voltage = 5; driver.Parameters.HighLimit = 200; driver.Parameters.LowLimit = 0; driver.Parameters.HighLimitVoltage = 6; driver.Parameters.LowLimitVoltage = 0; driver.Parameters.Offset = 10; driver.Parameters.OffsetVoltage = 0.2;

driver.Parameters.Frequency = ARI32XXLib.ARI32XXFrequency50Hz; #DC do not

support frequency configuration
driver.Files.Save();
For the HYAMP 4, all of the test parameters would be within a file. Therefore, you need to create a file first and then select a file to be edited. For the previous firmware version, it does not support the methods of AddGNDTest(). Therefore, we have to add the steps with default values using the AddGNDTestWithDeafults() and then modify the parameters. At first, there is a try-catch process to handle creating files with the name might be existed.
4.3 Load file and start a test

Start test driver.Execution.Execute()

Before running output, you have to select a file to load using driver->files->Load(). And then invoke driver->Execution->Execute() method to start a test.
4.4 Measure during test

Measure lastOpcStatus = False while(True):

print(driver.Execution.ReadTestDisplayRaw()) driver.System.WriteString(“*OPC?n”)
28105 N. Keith Drive Lake Forest, IL 60045 USA Toll Free: 1-800-858-TEST (8378) US/Canada Phone: 1-847-367-4077 | Fax: 1-847-367-4080 | www.arisafety.com

opcStatus = driver.System.ReadString() if (‘1’ in opcStatus and lastOpcStatus):
break lastOpcStatus = ‘1’ in opcStatus time.sleep(0.1)
This while loop would run with the condition of state is testing. Using the methods of Execution.ReadTestDisplayRaw() could let you read the immediate readings. 4.5 Close the session

Reset test and close connection driver.Execution.Abort() driver.Close()

print(“Done – Press Enter to Exit”)
Close() would close the I/O session to the instrument. 5 Completed example
The completed sample code could be find at the path of “IVI FoundationIVIDriversARI32XXExamples”.

5. Getting Started with LabVIEW
Introduction
This chapter describes the procedures of using the IVI-COM driver of Ikonix Group by LabVIEW programming language. In this exercise, the programmer could learn how to import the driver and complete a short program controlling the device step-by step.
Even though the programmers could control the device by IVI Driver. For the LabVIEW programmer, we suggest that using LabVIEW plug & play driver would be easier for your programming and debugging. The LabVIEW driver from Ikonix Group are all made up with commands directly, so you could clearly check how the commands were sent to instruments.

1 Open a new vi. 2 Import the DLL component.

Development

Open the Function Palette by right-clicking on the block diagram. Then select Connectivity -> ActiveX. Select or drop the Automation Open function on the block diagram. 3 Right-clicking on the Automation Open and select Select ActiveX Class -> Browse will open a window for choosing the DLL. 4 Select the Browse button and select the file ARI32XX_64.dll located at IVI FoundationIVIBin. The IVI ARI32XX Type Library would be added into the Type Libraries drop down menu. 5 Select IARI32XX and then click OK to complete creating an object of HYAMP 4 driver instance.
The Labview will automatically generate an Automation refnum of ARI32XXLib.IARI32XX control and connect to the Automation Open function.

6 Create an Invoke Node function and connect the reference to the output of Automation Refnum and then click on the Method and select Initialize to initialize the connection with device.
For more detail for the parameters of the Initialize() method, please refer to the help document, ARI32XX.chm located at “IVI FoundationIVIDriversHYAMP 4″. The first parameter ResourceName is a string type and indicates the interfaces type and address of the connection. The resource name,”ASRL9::INSTR”, represents a serial port with address 9. For example, a GPIB connection could be “GPIB0::8::INSTR”. For TCP/IP connection, it will be in the format of “TCPIP0::192.168.0.1::10001::SOCKET”. The 10001 is the TCP/IP connection port of HYAMP 4. If you use serial port to connect to device, please follow the above example, “DriverSetup=BaudRate=38400”, to setup the baud rate. There are other parameters for the option of the Initialize() method, please refer to the ARI32XX.chm for more detail.

6.1 Create file and setup test
Use the Property Node to get reference of the sub-system of IARI32XX class. For example, Files is one of the sub class of IARI32XX, and then we could use the Create method under Files to create a file in the device. For the HYAMP 4, all of the test parameters would be within a file. Therefore, you need to create a file first and then select a file to be edited. The methods of AddGNDTest is unavailable for the previous firmware version. Therefore, we could add steps with default parameters first and then edit the parameters. Please be noted that the flow of error data could make sure that the procedure ran sequentially.

6.2 Start a test and measure
Before running output, you have to select a file to load. And then invoke Execute method to start a test under Execution class. The Execution class is one property of the IARI32XX class. This for loop would run with polling the state and meters. Using the methods of ReadTestDiaplyRaw could let you read the immediate readings. ReadTestDiaplyRaw is one method of IARI32XX.Execution. There is another commands querying states of the device, polling “*OPC?” could get the running status. Please be noted that the status between step and step might be OFF for a shot moment. To avoid reading wrong status, we use shift register comparing the status.

6.3 Close the session
Close() method in IARI32XX class would close the I/O session to the instrument. Also, all of the references should be closed using the Close Reference function. 7 Completed example
The completed example with the state machine design pattern for your reference which are located at the path of IVI FoundationIVIDriversARI32XXExamples, including C#, C++ and Python as well. However, we suggest that using LabVIEW plug & play driver would be easier for LabVIEW developers. If you need a LabVIEW driver, please download it from the website of Associated Research or contact the vendor.
