[EMAIL PROTECTED] it would be much appreciated.And i would be
interested in purchasing the source code.
Thanks Stuart
I am communicating with the device where it uses RS485 to scan for the
device and report the devices available.
Is there any template or example VI which can be used as startup to
Wake Up from sleep mode, unit will acknowledge. Power on Self test and
reboot and the unit will respond?
thanks!!
One more thing;
I used these devices in another project.
In that case we used Brooks 154E's that were controlled and monitored
using AI and AO from FP.
So there are other options.
The Brooks Smart DDE software let users manage the calibration and
other settings of the MFC's. I would be very sup
Hi Stuart,
I tried 3 times to post my files and it would not work!
They must be to big.

Now forgive the following;

Hi, thanks for your help. i've just been told by my supplier of mfc's
that there is no labview example for these mfc's. If u still have it
could i have a look at it. be much appreciated.
Thanks Stuart

I had a look at writing my own drivers using RS 485 and the Hart based
protocol, but this seemed like too much work for our time frames.
I ended up ordering the controllers with DeviceNet communications
option. The Brooks manual for this seems pretty good, and I am busy
developing the application
I did an app that used these a couple of years ago.
Brooks had a LV example that used the DDE interface to the their
dirver.
I used that as a guide and was able to figure out what I needed.
Brooks support fro their example was pretty limited. I remember
getting a phone call back (a day latter) f
Hello Staurt,
I found the following on the Net:

So you could use the "Brooks Smart DDE software" with LabVIEW. The
DDE VIs in LabVIEW are not on the palette anymor. You can get to them
by going to vi.lib\Platform\dde.llb. You may want to fir
Hi, i'm currently going to be writing a piece of software to control
RS 485, brooks 5850s mass flow controllers. First question is does
anybody have any drivers for these mfc'. If not i would appreciate any
examples(PROGRAMS ETC.), advise on RS 485, addressing RS 485 as i will
be usin
Hi, i'm writing a program to control 24 Brooks 5850s mass flow
controllers. I will be using rs 485 to communicate with them. I'm
currently looking for a labview program that communicates with.
Otherwise i write one myself, the protocol it use's is the hart
protocol and i was wonde
I wanted to add a quick note to what Mads had mentioned.
If you are using LabVIEW 7.0 then you can use the I/O Assistant, which
will help you get the communication up and running quickly. In
addition it helps you parse out the results, and when you are all done
it will generate LABVIWE code for y
RS485 is used by thousands of different units. Normally it will look
just like a standard serial port to the application and you can use
the serial VIs to communicate.
The scan for device, acknowledge etc. that you describe is not part of
the RS485 standard, it must be something specific for the d
