MKS PR4000 CONTROLLER driver for labview 8.6

[MYLONG]

I need to interface the MKS PR4000 (two chanels for pressure transducer) with labview 8.6. Do I need to install the particular drivers? Where can I find it?

Thanks

Did you try to find it from the Tools>Find Instrument Driver menu? In any case, there is the Instrument Driver Network and it has a driver for the PR4000.

Dear MYLONG,

 In my lab. we have this instrument (MKS PR4000) for readout of two capacitance manometer gauges (0.05 mbar and 1 mbar full range). Our PR4000 has serial output (RS232).

 I wrote a small program in LabView for pressure logging long time ago.    If your PR4000 also comes with serial output than I can send it to you.

Let me know.

best regards,

 Bojan

 Dear Bojan,

If you can send me, I pretty appreciate it. My email: fan_long2002@yahoo.com.cn

Thank you so much!

That version is for labview 6.02. My labview is 8.6.

Is it ok?

Thanks

Whether it is okay or not will be for you to determine. It is not supported by NI.

Hello BZajec,

I read your email regarding the PR4000.

I am trying to communicate with A PR4000 (single channel) device via RS232.

You mentioned in your email that you had written a program for this. If you still have it available could you please send me it and I will re-develop for the single channel PR4000. I am very confused with the command syntax used as described in the PR4000 manual.

Thanks,

Nevica

Hello Nevica,

 before sending you the program you must establish a communication between your computer and PR4000. I assume you have not succeeded in this. 

 Try this below, before I send you the program. If it works, then let me know and I will send you the program. 

First you need to setup the pr4000 (by pressing keys) communication. I have done this long time ago, but as far as I remember it should be pretty simple. I hope you have a manual for pr4000, otherwise you can get a somewhat older version e.g. here:
http://www.lesker.com/NewWeb/Process_Instruments/pdf/PR4000F_EN_0500A1.pdf

Setup the communication (RS232 interface) to 9600 baud, Parity: NONE

I also hope you have a proper cable to connect the pr4000 and your computer.

I attached a simple program that you can use to verify the communication of pr4000 - the program is in labview.

 In the "port number" enter  0 for com1, 1 for com2 port etc.

In the "String write " field write a command, e.g.  "ID"     (without quotation marks and do not press enter at the end)

the run the program. If everything works fine, you should get a string starting with PR and several numbers. ID command asks for identification.

Then try AV1    and you should get the value of channel1.       See the manual for other commands.
I hope this will work.

Once you have this working, let me know and I will send you the program.  I am asking you to do this test first, because my program is very simple and will not work in case the communication is not established.

regards,

Bojan

Hello BZajec,

Thanks for your reply.

I have set up the instrument via null modem (crossed) RS232 cable and have communicated with the instrument via hyperterminal in Microsoft XP. The only command to which I have had a response is 'v' which has returned 'PR41413602' and what is I think the instrument ID.

I have tried sending the command 'AV1' but I get no response.

I am very unclear from the PR4000 manual as to what the command syntax is.

Also I have tried running one of the PR4000 Labview Vi's. I am having a VISA problem which I don't know how to solve. Are you able to help me with this. (Please see attachment for screenshot of the problem.)

Also I have the latest vesion of Labview (9) and I cannot run your vi because it is an earlier version. Could you please tell me which version you are running?

Thanks for you help,

Nevica
