Mks mass flow controllers only giving 2 sig. figs. over deviceNet and labview

We can only read 2 digits (before the decimal point) on an MKS deviceNet mass flow controller using Labview 2013. Does anyone know a solution to increase the resolution on this device? We should be able to read 3 digits past the decimal point.

Hi David,
Could you also specify the type of mass flow controller device?
According to our engineer, we had the APIs to set the attributes of DeviceNet device, but the specific type of the device is required. Attached is the document of some device type. You could turn to page 75 to see there the S-Analog Sensor Object Attributes::FlowDataType could be Get/Set.

Connect to MKS Alta 1480 Device Net Mass Flow Controller

I have a MKS Alta 1480 mass flow controller (MFC), MFC Manual, Labview 8.2 and NI PCI-CAN card. I know have the MFC wired correctly because I can operate it using another program on the PC that used the deviceNet interface. I want to talk to it via Labview. Everything looks OK using measurement explorer. I have the NI-DNET pallet. I know the MACID. I have downloaded the EDS from the manufacturer.
Here is what I am lacking: A general clue about the DeviceNet interface. Is there any example code out there that could get me started? Are there any tutorials on how to figure out the Dnet protocol? I am used to serial devices command--> response. I don't know anything about Class, Object, attirbutes.
Thanks,
Joe
Solved!
Go to Solution.

Joe, you can read MFC Flow value from S-Analog Sensor Object.
Class Id 49 (0x31), Instance Id 1 (0x01), Attribute Id 6
(0x06)
The default Data Type is Integer and Data Units is counts
If you want read from assembly object, you will
have establish polled IO connection, then use Read DeviceNet IO.vi to read
flow.

Mass flow controller

hello,
does anyone have or know of a vi that can be used to read and display mass flow of a gas?
i have a mass flow controller(MFC) and it reads the gas flowing thru a pipe (or a tube, forexample). i want to be able to take the readings or signals from the MFC and display it on the front panel.
does anyone have something(VI) of the sought that i can maybe modify to do what i'm trying to do?
thanks

A lot of MFC's have an analog out denoting the "is" value of the mass flow.
Connecting this analog out (from the MFC) to an analog in of a DAQ card will allow you to record the values.
This is an easy thing to do (If your MFC has a simple analog out), so I'm not sure if you'll find ready-made functions for it.

Producing a voltage that coresponds to a setpoint for a mass flow controller.

Hello,
I have a mass flow controller that requires a voltage output signal from my DAQmx board (SCB-68) to maintain a setpoint. This set point is a voltage that corresponds to the desired flow rate. I have produced a scale for this linear controller but I do not know how to use it.
I know how to create a vi that reads a voltage input, I can also write one that sends the same voltage input back throught the output. I can not write one that sends a constant voltage output corresponding to a flow rate.
Could somebody help me out with this?

Hello,
First, tp upload code (or any document) it is quite easy, just select the file, by clicking the "browse" button... see image below (I'm sorry it's all in french... 'cause I am french ! "Parcourir" means more or less "Browse" ) :
About your app, well adding a channel doesn't require to duplicate the whole code... Developper are always trying to do things with the less code possible . Check VI attached and tell me if it matches your needs.

Mass Flow Controller PS-54D

i am currently working on the device PS-54D Mass Low Controller. I am suppose to create and interface on Labview 7.0 to control the device. However, in the reference book of the device, there isn't any codes given for me to control the device. So i am wondering if you all have the codes that i need to write a program for this device.
Thank You.

Hi tyl,
What interface does the PS-54D Mass Low Controller use? GPIB or serial? There are some basic examples in LabVIEW to get you started with simple communication, and most instruments respond to commands like *IDN?, but you will need to speak with the manufactuer of the PS-54D to get a listing of function references for this particular device. Good luck!

Mass Flow Controller Driver

Hi,
I have a Brooks 5850E MFC and a HART driver for it that used with LabView which I downloaded from NI.com. What hardware connection does this driver use to communicate LabView with the device (MFC)?
Thanks

Sorry but I think you as the user should know what hardware connection your device uses.

Labview programming to convert weight measurement into mass flow

Hello,
I have continuous analog input measurement from weight scale. I want to convert the weight measurement to mass flow measurement.
E.g.:
1st minute weight measurement: 200kg
2nd minute weight measurement: 300 kg
3rd minute weight measurement: 350 kg
and so on.
I want to convert those weight into mass flow which is
1st mass flow300-200)keg/1min = 100kg/min
2nd mass flow: (350-300)kg/1 min = 50 kg/min
and so on.
So the weight and should be updated every minute, whatever the time value of while loop iteration.
Can somebody give solution of this case with labview programming? (structure in block diagram)
Thanks,
Eko

Hi Eko,
is this some kind of homework?
Well I suggest to use two shift registers to hold mass and time, then two subtract nodes to get the difference of current and old vlaue for both and finally a simple divide to get the mass flow...
Look here to get the basics!
Best regards,

PID Troubles on a Flow controller???

Hello,
I'm having trouble using PID control on an flow valve that requires a 0-12VDC power source. My setup includes an Agilent 34970A with a mulitfunctional module to output power to a Kepco power supply which ouputs power to the flow controller. The only way I can get PID to work is if I use a very small Gain such as (0.2), an Integral Time of (-.49) and a Derivative Time of (.005). It seems to dial in the flow meter within 2-3 minutes but it doesn’t seem right to put a negative value in for the Integral Time though?? I'm wondering if it has something to do with the hysteresis of the flow meter. Have you guys heard of anything like this happening with PID on a control valve? Please let me know.
Thanks, Jeff
Flow controller manf: Teknocraft~Standard proportional control valve.
http://www.teknocraft.com/pdfs/proporvalve1.pdf
Solved!
Go to Solution.

Hi
I am trying to write a simple code on Having a Loop control on a flowmeter. I wrote 2 codes one involving a P control and one Involving a Differnce in the set Point to the Actual output.
The idea is to control a flowmeter based on the pressure of flow . The Pressure measurement gives a Voltage output and the valve need a Current input so i need to control flow using desired Voltage output. But my code with the P control doesn not function as desired. ANd the code which uses just a differnce in a loop seems to work fine but for the fact that it never touches the desired value . it keeps oscilatting around the desired set point.
Could anyone help me set right the P Control ?

Need mass storage controller for Equium A110-147

Hello. I have an Equium A110-147 running windows7 ultimate with 2g of ram and a 500 g hard drive.
In other devices in device manager I am informed that my mass storage controller drivers are not installed. When I try to update the drivers I am told the drivers cannot be found on my computer or on the web.
I would apreciate some help on this if possible please.

Hey,
If you dont post the vendor and device ID its hard to say what driver you need
Theoretically Mass Storage Controller could be related to internal card reader module. You can download it on official Toshiba website:
http://eu.computers.toshiba-europe.com
But I think you must search for Vista drivers because Equium A110 doesnt support Windows 7, only Vista.
And you must search in *Archive* on driver download page because its an older model. ;)

Unrecognised Mass Storage Controller on Satellite A100-680

Hello,
I have a Satellite A100-680 (PSAA9E) that has been running XP Home for about two years. Very satisfied!
I decided to upgrade to Vista Business, which worked very well (actually impressed by easyness of install).
The machine works perfectly , there is only one irritating factor - under Device Manager - Other devices I have some thing called Mass Storage Controller and it does not have a driver loaded. I have been trying to locate one, but I have no idea what to look for.
Vista at some point suggested some Texas Instrument PCI device, but..... let me put it this way..... luckily I did not have to reinstall since I had made an image backup of the disks.
Can anyone give me a hint what I should look for.
Thanks in advance
Hans
Edited by: Admin

Really nice, that your Win Vista installation worked so good.
For this unrecognised device, I too think that it is the Texas Instrument card reader.
Go there: http://eu.computers.toshiba-europe.com
And download the Flash Media Driver and maybe SD Memory Format. Install them, reboot and device should be installed without any problems.

Satellite A200-1CR - Driver for Mass Storage Controller

On my Satellite A200-1CR / Windows 7 Pro I see yellow "Mass storage controller" in device list. What driver I should install?
Also my cardreader is not work now.

Hi mate
In your case I recommend checking the Device ID and Vendor ID which helps you to get more details about the device and needed driver.
Here you can find a nice HowTo:
[How to identify an unknown device?|http://forums.computers.toshiba-europe.com/forums/ann.jspa?annID=78]
If the Mass Storage Controller is the Card Reader device, then you would need the Flash Media Driver but I found only the driver for Vista, however, I recommend checking this driver even if its has been released for Vista and not for Win 7

Mass Storage Controller Error

Hi all
I get a "Mass Storage Controller" error in device manager after a new install. I have nothing unusual in my opinion, my config is listed below. FYI - I havnt yet installed the drivers for "nVidia Firewall" and "Forceware Network Access Manager" - not sure if this could be related.
Does anyone know what could be causing this?
(some of you may recognise my request from a previous thread, which started to get off-topic so I started this new one)
My config is:
Windows XP Pro (standard install without RAID drives for nVidia or SiS)
MSI K8N Neo4 SLI Platinum
OCZ 520W Modstream in Thermaltake Tsunami Case
Athlon 64 3000+
Zalman 7000B Alcu cooler
1 GB Crucial Ballistix PC3200
Gigabyte 6600GT
WD Caviar SE 80GB SATA
Generic DVD-ROM
Onboard audio
USB Mouse
USB Keyboard with Fingerprint Reader
USB Gaming Device ("The Claw")

Problem solved - I disabled the SiS RAID controller
Interesting that it was giving a device error while set to Enabled/SATA

Satellite Pro P300: Need Vista 64bit 'Mass storage controller' driver

Hi, please help.
I've just upgraded my laptop from Windows Vista 32bit to Vista 64bit.
I've managed to find all the drivers apart one: The 'Mass storage controller' driver (yellow exclamation mark in Device Manager).
I don't know where to look for this driver.
Any help would be appreciated. Al

Hi
I assume you didnt search in forum for similar questions? Is it right?
I think Im right because I searched in the forum and found this Toshiba FAQ doc.
+No Windows XP driver for PCI Memory Controller+
http://aps2.toshiba-tro.de/kb0/TSB83023N0000R01.htm
Here you can find this text passage:
After installing Windows XP there could be a yellow exclamation mark by a "PCI Memory Controller" or *"Mass Storage Controller"* in the device manager.
_Solution:_
This device is likely the Turbo Memory former Robson module.
This hardware will only supported by Windows Vista.
Therefore there is no Windows XP driver.
Now everything should be clear ;)
