Connect a Power Supply (IPS603) over RS-232 in LabView

Dear friends,

 

I am having a problem with my project. I have done some programs before in LabView, and my actual project is now to connect IPS 603 DC Power Supply serially and sending/recieving data in order to change input voltage from the computer without touching the hardware device.

I actually already connected the Power Supply to my computer ,I also, with the help of people on this forum, build driver for my power supply.


So now the problem is I can't set any value to the power supply. All that is working for now, I can only read actual voltage and current of the power supply but can't command the supply to change it 's actual voltage level. I can set connection with the power supply and put it in "remote" mode, and can read via VISA actual current and voltage. But  when I try to set new values for Current limit and voltage level I just receive a Bip from the supply and nothing change.

Can anyone has experinced the same issue and help me resolve this matter? I have no idea what can be the problem as I can actually send a command to read the actual outputs (Current and Voltage) but can't change the actual value to the desired values..How can I let the LabView to send a new voltage to the hardware?

With best wishes

 

Serge

Hello Serge,

 

It seems like you are definitely on the right direction, this may simply be an issue with the commands that you are sending to the device. For example the device might be expecting a string "k,2.35" and you are sending "k-2.35" or some other sort of syntax issue.

 

I was able to find a driver for the Oxford Instruments oxps Power Supply which mentions that the IPS model was tested using this driver. Unfortunately this driver is built for GPIB communication and was developed in LabVIEW 5.0 and has not been updated. This driver may be a resource for determining how the device is expecting syntax or other configuration data. If there is an issue with the version of LabVIEW, you can look at the Version Conversion Discussion board and consider posting there for some helpful user to bring the driver up to a version that is compatible with the version of LabVIEW that you are using.

 

Here is a link to the Driver page on ni.com which links to the manufacturers website:

Engineers have been controlling instruments without using drivers for quite a long time. 

 

If you are not able to physically connect to the power supply with a serial cable then you have bigger problems.
