GPIB control of HP 6034A power supply

I would like to find drivers for GPIB control of HP 6034A power supply (LabVIEW 6.1). There are drivers HP6xxxA for power supplies 6033A, 6035A, 6038A, ... Could anyone give me information how to modify these drivers for 6034A or any other directive. Jokut

You might post your answer in the Instruments Connectivity >> GPIB section of the NI Exchange forum.

PS: Most of the time you might just change the initialisation string of the instrument setup function/command if the instrument is similar to the dirver you already have. But this is all relative to the instrument - Unfortunatly I don't know the driver nor your instrument.

Using NI LabVIEW PID.vi to control 4 quadrant dc power supply in MOKE application; but the Process Variable won't achieving Zero Set Point, oscillating either side of zero instead !! Please help me to resolve this issue

Please see the image also where the PID values can be seen.
Thank You

Hi Aruvi,
PID controls are made for linear systems. When your system acts nonlinear you need to use a different control algorithm - or adapt your PID to use different PID parameters depending on system workpoint!
In the PID toolkit you will find a GainSchedule function that helps you in this matter…
And PLEASE put more text in the message body and (much) less in the topic title!

Controlling HP E3632A Power Supply

Problem Description : I need help with controlling the HP E3632A Power Supply. I used the instrument driver from your website, but it does not seem to work well. Here is the link to the driver I used:
http://zone.ni.com/idnet97.nsf/9b2b33e1993d877786256436006ec498/0817568e8af393c5862568ab005fbd3d?OpenDocument
I upgraded all the necissary software to use the driver, but it does not work properly. When I tried using the sample Getting Started program on the driver and told it to ramp the power supply to 5 volts, it only went to 3 volts. Also I would like to know how you would program labview to make the power supply go to a certain voltage and maintain it. I want the power supply to send out a constant voltage for a certain period
of time.
The only thing the Power Supply is connected to is the GPIB card. The getting started VI does not maintain the voltage. When i set it to go to 1 volt it goes there, but then drops back down. I want it to maintain the
voltage

I don't have this instrument available to test with directly, so I can only offer some suggestions.
First of all, it looks like the menus aren't quite right, so you have to load the Getting Started VI with File -> Open, not through the palette menus. I think you figured this out, though.
I think the main subVI you want to use is "Configure Output". If you just use a simple program with Initialize, Configure Output and Close, does it maintain the voltage?
If not, then I would try leaving out the Close. Does this make a difference?
If you are using Windows, you might also try using NI-Spy to look at the messages being sent to the instrument. Maybe you can figure out that the driver is explicitly resetting the instrument. If so, we can look at th
e driver more closely and figure out how to avoid this.
I hope this helps you get started.

Keithley 228 power supply

Hi, i have written a labview program to control the keithley 228 power supply. If i input 5V and 1A into the power supply from my front panel when the power supply is turned on, the power supply display panel will display 5V and 0.2A. The 0.2A is the current which is drawing by the DUT. My question is if i were to display the 0.2A onto my labview program on the front panel, i need to input a 1000ms into the timeout of the GPIB read function, inorder for the current to display out. If i input less than 1000ms, the current is unable to display out. But i need fast reading and measurement, the 1000ms input into the GPIB timeout have affect my testing. My hardware configuration consists of the keithley 228 power supply, 7053 switch card and 7002 switch box.
I have tried using the 228 driver from the NI web, but it don't seems to work. You may take a look of the attachment file of my written VI. Please advise.
Thank you.

Hi Desmond
Try to add an extra endcharacter to your string.
I saw that you rely on EOI (End or identify) and the keithley should respond.
But maybe it is faster in mode 3 (add CRLF)
I'm talking about the send/read data
Furthermore...
You are using a sequence frame for sequencing the write and read..
You can use sequence by wiring instead.
See case 3 of your vi.

Connecting LabView with TDK-Lambda ( Genesys )Power Supply

Hello, I have a task of controlling my TDK -Lambda power supply (GENH 60V-12.5A) with the Lab view. I have already downloaded the drivers for it. It would be of great help if any one could provide me with a sample Labview code/program to command and control the voltage and current outputs of the power supply. Thank you...

Every Genesys supply I have tried had the exact same SCPI protocol. So those should work for your supply. But you won't really know until you try it.

Hameg power supply HM7044 ieee 488 (GPIB) device control

Dear All,
I have a power supply (Hameg HM7044) with a GPIB interface.It seems that there is no VI to control it in the HAMEG or the ni websites.
Since i am new to this kind of interface i have two questions.
-if i connect the device how do i know the address it is in.
-is there a general VI to interact with GPIB -ieee 488 devices?
thank you in advance,
thodoros

Well, there is a driver here but it is for RS-232 and for some stupid reason, they have password protected the VI. That should deserve a nasty message to them.
First, if you use an NI GPIB controller, you will get a program called Measurement & Automation Explorer (MAX). As part of the installation instructions, you will do a 'Scan For Instruments'. This will return a list of GPIB addresses for all of the connected instruments. Second, the information for setting the GPIB address is going to be in the instrument manual. If you don't have a manual, get one because you can't do a thing without one.
To communicating to GPIB instruments, the recomended API is VISA. The majority of the time, all that you will need is a VISA Write and a VISA Read.
You can learn some of the basics at the Instrument Control Fundamentals page.

GPIB-Controlled XHR Power Supply and HP34401A DMM Conflict

Dear Experts,
I downloaded a driver for XHR Power Supply from NI's website and used
it to controlled the power supply successfully via GPIB cable in
LabVIEW. However, when I used HP34401A digital meter to measure the
voltage from the power supply in the same way via GPIB cable, the XHR
power supply was shut down automatically although the meter read the
measurement correctly before shutting down. Since I am a new user of
LabVIEW, I do not know if it is a conflict of GPIB-Controlled
instuments.
I would be most grateful if you could give me some advice and tell me how to solve this problem at your earliest convenience.
Thanks a lot for your attention and help,
James

You can set LLO with the VISA GPIB Control REN function. This is on the Instrument I/O>VISA>VISA Advanced>Interface specific palette.
You do not use the same VISA session for two different instruments. Each must be different and unique. If they were the same, then the be would be using the same address and your program would not work.
To make a sinlg VI that will control both instruments, just take the functions you need from each and put them into a single VI. The author of the XAN power supply drivers did a kind of lame thing. The Getting Started VIs do not have their controls and indicators wired to the VIs connector pane so you would have to change this before using the Getting Started in another VI. I've attached a simple example that shows some of the other functions along with some 34401 functions in a single VI.
Before you get going, I would recomend that you take a LabVIEW programming class. Information can bge found at http://www.ni.com/devzone/lvzone/fundamentals.htm.
p.s. You should know that your email address is not available to forum users. If you wish an example program, you can request it be posted here but you need to provide the version of LabVIEW that you're using and you need to provide the exact name of the XAN driver you're using. I found three and don't know shich is which.

How do I use LabVIEW to control and vary the voltage on my Agilent Power Supply and simultaneously record temp from 1 DMM and voltage from another DMM?

I am using an Agilent Power Supply to apply a voltage to a
thermistor to heat an Al chassis. I want to use LabVIEW to tell
the power supply to apply 5V for 10 minutes, then step to 7V for 10
minutes, etc. I am completely new to LabVIEW, so any help would be greatly appreciated!
In addition to that, I want to place a type J thermocouple onto the Al
surface and use a Keithley 2000 DMM to monitor the temperature (it has
a built in conversion from V to Temp for type J). I will also be
using another Kelthley 2000 DMM to record the output voltage of a new
uncalibrated thermocouple. I would like to collect the output
voltage for this uncalibrated thermocouple and the temperature reading
from the type J simultaneously. How should I go about doing this
in LabVIEW? I will be using version 6.1. The power supply
and DMMs will be connected to a PC using GPIB.
Again any suggestions would be greatly appreciated- I have no idea
where to begin on such a project. I have taught myself how to
make a basic VI- converting temp in oC to oF, but that is as far
as my knowledge goes.

What you want to do should be fairly straightward and a good way to learn labview.
First off, if you haven't already, I would download the drivers for the Keithley and Agilent instruments. I found the keithley drivers at the link below. You will need to find the labview drivers for the Agilent PS at their website. Drivers are the VI's you will use in your program to control the insturments.
http://sine.ni.com/apps/we/niid_web_display.download_page?p_id_guid=E3B19B3E90B0659CE034080020E74861
If you open Labview and go to the help menu and click on Labview bookshelf there is alot of information on getting you started coding labview. This should get you started, if you have anymore questions just ask in this same thread and I am sure you will get all the help you need.

How can i change the voltage of my power supply using my pci gpib 488.2 driver?

I need to be able to control the voltage outputed by the power supply. I have a pci gpib 488.2 and I downloaded the correct driver. I also don't no exactly how to use the communicator included in the measurement and automation explorer. When ever I type in the commands I get an error. If anyone can help me I would appreciate it.
thank you

First see if you can establish communications with the power suppy using Meas and Automation explorer (MAX for short). If you can find your GPIB card in the directory tree choose it and then use the scan for instruments tool. If it can see your power supply it will give you it's address. Choose it and try the Communicate with my instrument tool. It will send a IDN? command to that address and it might return a string if the instrument understands the command. If not you will need to dig through the power supply manual to find the correct commands.

Help Using Labview to control Kikusui power supply with a PIA4850 controller

HI I need some help using Labview to control 4 Kikusui power supplies. We have a PIA4850 Kikusui power supply controller. I can use the visa test panel and see the PIA4850 but can see any of the power supplies. I have very limited use of Labview and only wrote a couple programs using GPIB. The PIA4850 is a USB controller and can control up to 32 PS. I can get it to work with a Excel demo software that came with the controllers so I know that it is working. Any help will be appreciated. I am using LabView 8.2 and have updated to the Ni-DAQ 9.0. I have a program that I need to incorporate the PIA4850 into once I figure out how to operate it. Thanks in advance.

HI and thanks for the help. I did get one power supply to work but have another problem. I need to control 4 power supplies at the same time and can only operate the one that is addressed N5!C1. If I set the other to N6!C1 and so on I get an error stating
“Error -1074135008 occurred at ki4800_2 Configure Voltage Level.vi Possible reason(s):IVI Error in the method "get_Item" in the component "Kikusui4800". E_IVI_UNKNOWN_CHANNEL_NAME: Unknown channel name (N6!C1)”
I am assuming that I should be able to change the node number and that will change the supply that I need to use. Everything works great if I use N5!C1 I can change any of the supplies to address 5 and can control it with no problem. I can even have multiple supplies with the same address N5!C1 (don’t think I should do that) and change them all at once. I need independent control of each supply.
I am in a pinch here and need to figure it out but could use some help. Any ideas will be greatly appreciated.
Thanks

Using LabVIEW for temperature control with AMREL SPS200-50-A022 power supply

Hi, I hope someone can help me out. I'm an ME undergrad with pretty much no knowledge of LabVIEW. I am working a project which requires a temperature controller. Previously, we were using an SPS120-10 power supply from AMREL and a grad student wrote a LabVIEW VI which performed feedback temperature control. The VI would acquire temperature from a Benchlink which acquire the temperature from a thermocouple. The VI also monitor the output voltage & current and determine the power output and heater resistance from those values. When a desired temperature is set, the VI compares the actual temperature to the set temperature and adjust the voltage/current setting to achieve the desired temperature. The VI was designed to keep temperature deviation to within +/-0.5 deg C. I'm not sure of the data refresh rate, but it's on the order of seconds since the system has a small thermal mass and we're operating in the 800+ deg C range. When we were using the SPS120-10, the device used GPIB for communication with the PC. Due to higher power output demand for the heater, we switched to an SPS200-50, which only has an RS-232 port. First of all, I was wondering if someone could help me modify the VI so that it could communicate with the SPS200-50 through the serial port? In addition, the drivers for the SPS120-10 and SPS200-50 might be different. If modifying the VI to communicate through the serial port isn't enough, I would need to figure out where to modify the VI with the SPS200-50 drivers, which is provided by AMREL. If anyone would like, I can send you the VI files so that you can take a look at the block diagram and tell me where to modify it. I'm still not 100% certain I understand how to read LabVIEW block diagrams.
Please let me know if you need any additional information. Any help would be appreciated. Thanks in advance!

I have looked over your vi. First of all you have to do some changes in the "ARSPS Initialize.vi" See picture.
The best way to check instrument communication is to send the *IDN? Command. The instrument will indentify itself in response to this command. The vi I have included is a labview example. Use this Vi to test your communication. Do not progress before this is working. The VI is also an excellent example on how to set up and close down RS232 communication.
The VI "Tfeedbackpowercontroller-nolvdt-Dinh.vi" looks OK so I guess it will work then your RS232 communication with the SPS200-50-A022 is working
good luck
PS as mentioned before you will find all the RS232 details in the instrument manual
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)

How to control HV power supply (0-5V control voltage)?

Hey there,
I (LV newbie) wonder how to control my DELTA ELEKTRONIKA Powersupply with Labview. The control interface is a 0-5V analog input to set the power supply's output current.
Also I want to get some feedback of the set power supply current from an second (GPIB-controlled) instrument.
So how do I have to program a closed loop contol (application is not time critical), cause it would be mixed up of controlling by analog out (0-5V) and feedback loop driven on the GPIB-Card?
For a first step a simple control loop to set the current and monitor it on an analog input would also be an assistance .
THX for anyone helping

Look in the example finder for DAQmx functions for analog input and analog output.

Spellman power supply SL40PN2000 remote control using Labview

We have a SL40PN2000 Spellman power supply. We want to do remote programming using Labview program.
We want to control the voltage output.
Many thanks for your help.

You need to first determine the remote control interface. Is it GPIB, RS-232, Ethernet, USB, etc.? In the case of GPIB, you would need to purchase a GPIB controller.
There is not an existing instrument driver but you can review the information here on what a driver is and how to devleop one.
