QL355TP Power Supply Automation

[satheeshvelu]

Hi All,
I'm trying to automate QL355TP Power supply using Python or LabView. If Instrumentation experts out there could you please share your thoughts?

Hi,

I established several remote controls for different kinds of instruments. Most of them can be controlled by SCPI [1]. I used MATLAB to write the control script, as Phyton is also a script language this MATLAB driver might be useful [2].

Hi Stenzer,

Thanks for your inputs. This is really useful.
I'm using the attached commands. Interface is USB. Internally the commands pass through UART. Defined COM Port & Baud Rate 9600.

import pyvisa
rm = pyvisa.ResourceManager()
rm.list_resources()
('ASRL1::INSTR', 'ASRL2::INSTR')
inst = rm.open_resource('ASRL1::INSTR')
print(inst.query("*IDN?"))

To read Voltage, the said command format is
V<N> <NRF> Set output <N> to <NRF> Volts.

print(inst.query("V1 5.00"))

I'm unable to get it this result.

I will also try with Matlab cos the driver is specifically for this PSU.

But eventually I will still need to get it done on Python/C# to support other interfaces.

Thanks,
Satheesh
