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

[antique]

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 antique,

  You can download labview drivers for your controller from

Thanks and regards,

There are also the Kikusui ki4800 Power Supply instrument drivers. This collection of VIs should allow you to control your Power Supply.

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

OK I figured it out. I just overlooked a part in the Kikusui IVI-COM instrument driver programming guide. After installation there is a scan utility that needed to be ran when all of the power supplies are connected? I ran it when I had the first unit connected but had not ran it with all of then connected. Once that was done they were all recognized and worked great. Thanks for the help.
