NI PXI 4110 Register-Level Programming Manual

[Tudor_ik]

Hello,

I would like to program my NI-PXI 4110 DC Power Supply with VISA, so I need to know if i can find a register-level programming manual  for this module. I would also like to know if there is anyway to convert SCPI commands into register-based commands. I would greately appreciate if someone could help me.

Thank you, 

Tudor

Hi Tudor,

At this time, register level programming of the PXI 4110 is not supported.  What kind of system / application would you be needing this for?

Hello David,

I would have liked to control the DC power supply 4110 on my PXI system vith VISA functions, and because the PXI does not support SCPI  commands I would have liked to control it with register commands. My goal is to control the PXI modules remotely , with VISA. I succeded in doing so with Instruments that are connected with GPIB(because they support SCPI) but I am having a lot of trouble with the PXI system.

Thank you,

Tudor

Tudor,

I believe what David was trying to figure out is whether or not our driver with LabVIEW, CVI, or Visual Basic support would work with your operating system, etc. Are you programming in an environment that doesn't allow the use of one of these APIs, such as Linux?

If you have further questions that are more appropriate to take offline and have support service, feel free to call in to 866-ASK-MYNI (275-6964) for further clarification. If not, if you give us permission to contact you, we can get your contact information.

Thanks!

Hello Mark,

My operating system is Windows XP, and I am using Labview to control the PXI. I have no problem in doing this from the computer that is connected to the PXI system directly, because I have all the necessary drivers installed. The problem is that I want to run a Labview program that can control the PXI modules from a computer on my local network. For example if I want to control the NI-PXI4110 DC Power Supply I must set the niDcPower Initialize.vi resource name parameter to Dev4. But if I try to open a VISA session the instrument handel  given by the VisaOpen.vi is

visa://server ip address/PXI5::9::INSTR( which is not a valid resource name for niDcPower Initialize.vi). I know that my problem could be solved by using the WebPublishing Tool or Remote Pannel Connection, but I was trying to do this with VISA functions in a Labview program( in the same way I succeded to control GPIB instruments with Visa read/write).I hope that this time I made my problem more clear.

Thank you,

Tudor

Hi Tudor_ik,

Thank you for clarifying your application for us.  Since the register level programming with VISA functions are not currently supported, please let us know if you would like assistance implementing the other options.

Dear David,

Thank you very much for your response.Since regiter-based Visa functions are not supported, I will try to approach my application in another way .

I'm a little surprised this is not supported.  How does a user access and control a remote resource?

Surprisingly, the NI-DCPower 21.0 Soft Front Panel (SFP) does not detect remote PXIe devices.  For some reason, the SFP software is only probing devices on localhost.  Clearly, the PXIe card will not be detected by the SFP.

 Here the PXIe-411X Getting Started Guide states that the SFP should be able to control the device.  How does the SFP control a device that it can't detect?

What am I missing?

Kindly please start a new thread but do not continue a conversation on a thread that is more than 10 years old.

What do you mean by a remote PXIe device? Are you trying to control the device on a remote Windows computer?

Soft Front Panel only works on the remote RT target.

For remote Windows targets, you can consider using https://github.com/ni/grpc-device

The PXIe-411X is installed in a PXI chassis running NI Linux RT.  The Windows Host PC is connected to the PXI chassis via LAN.

I'm a little confused.  The PXI chassis is not running Windows.  For those unaware, NI has moved to NI Linux RT for all RT controllers (i.e. PXI, cRIO, sbRIO, ...etc).

Is there a Soft Front Panel for the NI Linux RT Desktop Environment running on the PXI chassis?
