controlling a potentiostat and perstaltic pump

[student (project)]

how to make a connection between a perstaltic pump and computer to use labview in controlling the equipment on and off state and its flow rate in an electrochemical experiment with an ivium soft potentiostat which has a software bundled with labview. Any idea i'm really new to this

Hi,

You're going to need to give a lot more information before anyone can really help you with this. I've had a look at the Ivium website and they say they have a LabVIEW instrument driver. I'm not sure if you're familiar with LabVIEW but an instrument driver will typically contain a driver, to interface the device (ivium soft potentiostat) to the PC, as well as a number of LabVIEW functions.

Once you've connected the device up to the PC and it appears in the device manager you should be able to start using the LabVIEW functions to control it. Open LabVIEW, Navigate to the block diagram and right click to bring up the Functions Palette. Go to Instrument I/O >> Instrument Drivers. Provided the driver installed correctly (and they do provide LabVIEW functions) You'll see a sub-palette which should interface with your device. Keep the context help open (ctrl-H) and hover over a few of these functions to see what they do.

I would have downloaded the driver myself to have a look at the functions, but I can't seem to find it online.

If you haven't used LabVIEW before I would definitely recommend following through some of the tutorials at the following link:

With regards to connecting the pump up, what kind of connections does it have, do you have a pin diagram? Do you have any NI DAQ hardware with which you can interface to the pump?

Kind Regards,

concerning potentiostat the example within ivium manual of labview enabled be to control potentiostat . My main problem is the integration between the two devices and the control of the pump i don't have DAQ. I will attach a pin diagram for the pump as requsted . my main problem is the perstaltic pump.

The link below shows the arrangement of pin diagram pump model 101u/r.

The lab view program should enable the user to turn the pump on and off. To speed up and speed down the rate of flow of the pump in an electrochemical experiment such as cyclic voltammetry as well as EIS. The Potentiostat i have is compactstat which has labview bundled with its software. The idea is to control both potentiostat and pump durring an electrochemical experiment.

That pump has options for remote control using logic signals and a continuous voltage or current for speed control.  You will need to have some kind of DAQ device to generate these signals. The speed control signals are outside the range of standard multifunction DAQ devices.  You will need to look at devices designed more for industrial controls.

Once you have selected an appropriate device, you can look at developing a LabVIEW program to operate it.

I need to control watson marlow 101u/r perstaltic pump. I don't know which DAQ will be suitalbe for controlling the pump speed and on off state and I'm really new to lab view. I would like some one to guide me with steps please. Here is an attached link to the pump pin diagram.
