Cryogenic SMS120C superconducting magnet power supply


Dear all,

has anyone here experience in accessing the aforementioned

"Cryogenic SMS120C superconducting magnet power supply"

over GPIB with LabView, and would be willing to give some hints / maybe
even share the code?

For details about the device, see the manufacturer website:
http://www.cryogenic.co.uk/products/electronics/power_supplies.asp

It seems to be pretty trivial to send commands to the power supply - "GPIB
Write" does the job and the device executes the commands (as can be seen
on its front panel). However I have not managed to get any status
information / command output back; when I do a subsequent "GPIB Read", I
always get only an empty line. ???

Thanks in advance for any hints;
best, Andreas

Hi Andreas,

Since you have been successful in writing to the device, it appears that your communication is working properly.  You may need to initiate a response or poll the device in order to read from it.  In order to read, the device needs to switch into talk mode, and the computer into write.  For specific information on this, as well as the exact communication protocol for your device, you will need to consult the user manual for the device.

You may also want to take a look at the following KnowledgeBase article, Why can I write to my GPIB device but cannot read back?

Regards,

Lauren L.
