Compact fieldpoint help!!

Hi, im currently using compact fieldpoint cFP-2120 with modules cFP-AIO-610 (X3) cFP-TC-120, cFP-RLY-425, cFP-DIO-550. The question i have is im using cFP-AIO-610 to measure Voltage. The issue that i having is that i can measure e.g. 3 Volts on channel 1, then i connect it to channel 2 (not while connected to channel 1). And it wont read 3 volts it gives less that a tenth of this value and the current is increasing to a large value if i try and increase the Voltage. Ive checked my connections on the cFP connector, MAX and everything seems ok. Is the module broke? could it be bridged? Ive even changed the module to a new one and same problem. What could it be??

Need help getting networked shared variables on compact fieldpoint to work

I'm still a newbie and am trying to get Networked Shared Variables to pass from a VI running on a PC to a VI running on a Compact Fieldpoint. I created a VI that sends a message via a Networked Shared Variable and a VI that receives it. I have them both in the same project. If I run them both on the PC, it works, I can send a message string from the first VI to the Networked Shared Variable and read it in the second VI. I have the second VI turn the LED "A" on and the LED "B" off if I send the string "a", and turn the LED "B" on and the LED "A" off if I send the string "b", and turn them both off if I send anything else. It works as expected if both the VIs are running on the PC. The second VI also continuously blinks the LED "C" so I can verify that it's running.
I "deployed" the second VI to the Compact Fieldpoint as follows:
In Project I dragged the VI from My Computer (under Project: name.lvproj) down and put it under the Compact Fieldpoint name.
I right clicked on Compact Fieldpoint name and verified it was set to "Connect".
I right clicked on the second VI and selected "Deploy".
I started both VIs with the "Run" arrow. At this point I know second VI is running since the LED "C" keeps blinking. But, when I try to send an "a" or "b" nothing happens, so the VI on the Compact Fieldpoint must not be receiving the messages in the Networked Shared Variable.
I also right clicked on Compact Fieldpoint name and selected
"Disconnect". The second VI continued to run since the LED "C" keeps
blinking, but I still can't get messages to pass.
Any help will be greatly appreciated.

I got this to work. I moved the library (.lvlib) containing the Networked Shared Variable to down under the Compact Fieldpoint name. Now it works.

How to install "Compact FieldPoint Embedded Data Logger Example Program" on cfp2200

i finally managed to get max to see the devices of my cfp2200.
(i had to disable every unused networkadapter due to overlapping subnets)
now i want to deploy the example programm "Compact FieldPoint Embedded Data Logger Example Program"
http://zone.ni.com/devzone/cda/epd/p/id/3221
i therefor have tried to install the runtime 8.5 on the target. however this is not possble, because i have labview 2010 installed and it gives the message:
"the host has a newer version available"
ok. runtime 2010 should work to - not?
i open a new project - import my *.iak-file and drag-n-drop the content of "cfp_data_logger_source.zip" onto the target.
now if i open the file cFPEmbeddedDataLogger.vi the run-button is cracked and by pressing it an errorlist opens.
the errors say stuff like:
target does not support this function/subvi
and
vi has been modified with a different applicationinstance
please help me to make this work.
i know that it is possible to get the programm to run on the cfp2200 even dough it is primaly designed for the cFP-2000, cFP-2010, cFP-2020, cFP-2100, cFP-2110,
cFP-2120.
big THANX already for you help !!!!!

Hi, thanks for your help=) I've manage to drag the file into my targeted controller. I am now doing the setting of the data logger program, but there's one thing I'm unsure of. May I know what does it mean by the cFP controller clock? http://zone.ni.com/devzone/cda/tut/p/id/3219 . Thanks. =)
Log On Startup
Start logging when the controller powers up.
Start Log Time
The time to start logging.
Stop Log Time
The time to stop logging.
Note: Make sure the clock is set correctly on the controller. The settings described above refer to the cFP controller clock.
Log Rate
The number of milliseconds to wait between each acquisition.
FP Drive For Data Files
The drive to store the log files in. The C: drive is the default for all cFP controllers. If you want to save to the removable CompactFlash drive on the cFP controller, select the D: drive.
Digital "Pause" Line
The Digital Input item to use as a "pause" button for data logging. Logging pauses when the signal is high. When the signal goes low again, a new file is created and logging continues if appropriate.
Note: Use only Digital Input items for the Digital "Pause" Line.
Tip: You can use DIP Switch 3 to block the current data from being logged. This switch works the same way as the Digital "Pause" line.
Logging Session Tag
Is stamped on the spreadsheet that the data logger creates.

Why should I prefer NI Compact FieldPoint to Siemens S7-400 PLCs?

NI guys please answer:
Why should I prefer NI Compact FieldPoint controllers to Siemens S7-400 PLCs to build an automation and monitoring systems for a factory?
I am asking this because one of our clients insists to use Siemens S7-400 family of PLCs to build an automation systems and we want to convince them to use NI cFP, but we need help from NI advisors to bring more satisfying reasons to our clients in order to change their mind.
The case includes 51 AI, 15 AO, 108 DI and 51 DO.
The whole process of this chemical factory must be automated and also monitored in a control room in two touch screen monitors and a big 52" LCD panel.
Any help will be appreciated from NI advisors!

For what it's worth, I'd like to make a comment. It's difficult to compare the various PLC vendors with the NI line of products such as cFP because everyone has their various perceptions. In short for me, the NI products are far easier to program than typical PLC's because of the much greater flexibilty and the rich features found in the LabVIEW programming environment. I've programmed several PLC projects over the years that include GE Fanuc, Allen-Bradely, Omron and Siemens (Including the S7-400 series) I'll take the LabVIEW environment any day over miserable ladder logic and the other versions such as instruction lists. The customer gets a better product when it is easier to program and test. I often provide features for the customer using LabVIEW and cFP that I would never think of doing using ladder logic. The bottom line is that it's too easy to compare hardware without consideration of the software or benefits of features available.
And then there are the customer's perceptions. Just the other day I met with a potential customer who hates Siemens with a passion because he had experienced a lot hardware failures. Conversely I have other customers who will not accept NI products only because they are not familiar with them. For example, their technical personnel are familiar with Allen-Bradley and so that's what they want to stay with. I have a very large international customer who has a corporate mandate to use Seimens. It goes on...
I consider my time to be somewhat valuable, which means that I have different pricing structures that are based on what the customer wants. When a customer requires a non-NI product, I literally double the charge for programming time. Some jobs I win and some I lose. However, I'm very busy in the mean time and will continue the preference of vi's over PLC programming.

Compact FieldPoint and Shared Variables

Hi Real-Time community,
let me first to describe my problem: I have a project running perfectly on Windows XP machine. The Real-Time Target (compact FieldPoint) is acquiring a data from different sensors and sends them via Shared Variables to the host machine (WinXP). Now this host application has to migrate to Windows 7 machine, which second Ethernet port is also connected to the compact FieldPoint's network. I have created an installer, it run on Win 7 computer but I I see no data there. Shared Variables are standart network-published. What else I need to configure to get Shared Variables visible over there? Thank you in advance for any helpful hint.

Hi,
we do have the full edition of Signal Express, this is not the problem. We are already logging the information comming from our cFP-1808 : TC-120 and AI-111 module. The problem is that the AI-111 module is a 4 to 20mA module, and we have thermocouple connect to it. We want to read temperature in Signal Express instead of mA.
There's a option in MAX where you can add scaling to a cFP module. This scaling work in MAX, in the OPC server of the cFP, but not in Signal Express. In Signal Express, you still read the mA value.
I know we can add a formula in Signal Express, but we don't want to do that, when there is an other option in MAX.
Thanks

Improving Boot Time on Compact Fieldpoint

Does anyone have any suggestions for how to improve the boot time of Compact Fieldpoint controllers? Right now, I've got some not real complex code with 2-3 Loops (lots of shared variables, though). It takes roughly 5-8 minutes for the loops to start running after the unit is powered on or rebooted. After they start running, the performance is OK but not great. I'm using a cfp-2020, but will be moving to a 2120 soon.
Thanks!
-Matt

I was also having problems on my cFP-2120 with the initial read on shared variables hosted on the cFP controller. I was working with only about a dozen shared variables and seemed to take several minutes before all the variables were up to speed. When I watched them on the variable manager, I could see them get their first values one at a time with about 5-8 seconds from one variable to the next. The FPremote.ini tip that I had seen in a few threads did seem to help. One comment I would add is that it didn't seem to take effect until after the controller was rebooted.
I would like to pose a few questions of an NI person as to why this file is needed? It isn't logical that the absence or presence of an empty file would have any effect on the speed of the shared variable engine. Are there any configuration settings that get added to it automatically? Are there any settings to be added that have any meaning to the shared variable engine? It appears to remain empty.
Has this behavior been documented as a bug within Labview or Fieldpoint? It seems that if something as simple as adding an empty file to a directory improves performance, a Fieldpoint patch or upgrade should be put in the drivers in the quarterly service CD's to take care of this automatically.
There should probably be a knowledgebase article on this in the official NI website rather than just the threads in the forums addressing this issue. I did a search for fpremote.ini from the NI home page and zero results came up.

Compact fieldpoint simulated device for simulation

I am preparing to use a compact fieldpoint device (cFp-2120) with some I/O modules for DAQ through ethernet communication.
However, the hardware is not ready yet.
Is it possible I can create a simulated compact fild point device with those I/O modules in MAX and then use these simulated devices just as the real devices in LabView to start writing the vi programs
Thanks
jinhua

Hi,
It sounds like you are interested in a feature similar to simulated devices like we offer with our DAQ devices. Unfortunately we don't offer this feature with FieldPoint. Let us know if we can help you in some other way and we'll be glad to answer any other questions you might have.

WebServer on a Compact FieldPoint

Hi,
In my project I make a lot of acquisitions of sensors, and I wanna do this with a Compact FieldPoint, and publish those measures on the web for controling from a remote panel on the web. But using the standart way of the remote control I had a problem. When I do 1 or 2 measures there´s no problem, but when there are more than 3 sensors being read the web page comes very slowly and after a short time MAX says that the CFp is disconnected. Is there anyone who can help me on doing this?
Thanks.
Vinícius Silva Lima.

Hi
One question:
- Your program is running in cFP?
Because all processcis dedicateds to the measurement of sensors, not providing time to make the communication with ethernet port.
Try give a time that task and see the result.

Getting started with Compact Fieldpoint

Is there a tutorial document to help get started programming Compact Fieldpoint in LabWindows?
Examples?

Hi!
I was able to find a few community examples involving LabWindows/CVI and a FieldPoint:
Simple FieldPoint Counter Example in LabWindows/CVI
Measuring Multiple FP-TC-120 Channels Using CVI
FieldPoint Simultaneous Analog Voltage Input and Output (FPVoltAnalogInOut)
Hope this helps!

Internet connection of Compact Fieldpoint controller

Hi all, I have this Compact Fieldpoint controller of cFP-2120, I need to make it stand-alone & also to be able to get my data directly from internet. Is there anyone who know's how to do it? Thanks=) For the controller's mannual I came across this sentence of "In order to configure the cFP-21xx, it must reside on the same subnet as the host PC. If you want to use the FP-21xx on a subnet other than the one the host PC is on, first connect and configure it on the same subnet as the host PC, then reassign a static IP address for the subnet where you want it to be
and physically move it to the other subnet." Do you all know what does it mean? Is this feature for stnad-alone or for internet connection?=)

Hi!
   You seem a little confused about networks, am I right?
   The thing is that to configure your cFP, it must reside on the same subnet as your PC. I make an example: you can assign your PC a static IP address, example 192.168.168.1, subnet mask 255.255.255.0, then your cFP-2120 will have to be inside this subnet, that is 192.168.168.2 to 192.168.168.254.   If you connect your PC to cFP-2120 through a cross ethernet cable, you can set your PC IP address to 192.168.168.1 and cFP-2120 to 192.168.168.2.   With this gear, you configure, program, and test your cFP application.
   If I understood your needs, you need to place the cFP-2120 remotely, and collect data over Internet, isn't that? If so, one way for doing this is activating a web server on the cFP-2120, for which you can find examples.
   The next step is to be able to view your cFP-2120 remotely, because of course you can't keep IP addresses you used for configuring cFP-2120. When placed remotely, cFP-2120 will reside on a different LAN, I suppose, and you need to access it from your PC. Unfortunately, I have no experience on this, but I think that once you configure cFP-2120, create application, create the web server, then you can turn to remoting cFP-2120.
   Some useful application notes are here, in particular take a look at links at the bottom of the page.
Hope this helps!

Ports used by Compact Fieldpoint 2120?

I have a Compact Fieldpoint 2120 behind a Linksys WRT54G router. What ports do I need to forward for MAX and Labview to see the router?
I have 20-21, 80, and 44525 forwarded to the Fieldpoint for both TCP and UDP. The ports listed HERE don't look applicable.

Hi Gizmaa,
Thank you for contacting National Instruments. From the information you have provided here, it looks like you are unable to see your router and Fieldpoint in MAX. If this is the case, you should not be seeing your router in MAX, but I can suggest some things to look into to hopefully see your cFP-2120.
From the article that you linked, the port that is listed within the Lookout/Logos Communication document is what is used for communication between the cFP device and the host PC. If you are enabling access to ports for NI hardware and software this might be something to consider. Aanother suggestion when not being able to locate your device in MAX, is to ensure that your anti-virus software or firewall configuration is not blocking the connection. I would ensure that this is not the case by temporarily disabling these programs and attempting to locate your hardware. If this is the case, you can then add the National Instruments software you are using as exceptions to both the anti-virus software and firewall.
I hope this helps! Let me know if there is anything else I can help with or clarify. Have a great day!

VB6 and compact fieldpoint

I have a request to add 4-20 mA and relay outputs to an existing VB6 application using compact fieldpoint. Is VB6 still supported by the compact fieldpoint drivers/software, and if so, what is the recommended interfacing approach?
Thanks,
-Scott Hein
Diablo Analytical, Inc.

Scott,
There does not appear to be nay reason why you cannot use VB6 with compact FieldPoint. The implementation of your application should be the same for FP and cFP. Here are some articles that reference this:

PoE switch and Compact Fieldpoint

Hello all... Is it possible to connect my Compact Field Point Controller to a PoE switch (Power over Ethernet Switch)??? This is because some other devices on the same subnet require PoE (IP cameras) and I wanted to know if this can cause some sort of problem with my Cfp... Should I connect the Compact Fieldpoint to a regular switch and connect that switch to the PoE switch??
Let me know any suggestions...
Thanks a million in advance,

Hi Jaime!
Currently there are only certain products that support the PoE standard, unfortunately the cFP family is not one of them. The best you can do is connect your cFP to a switch and then to the PoE switch like you said and check if that works. Here is the document where the PoE and NI products are described:

DSC for compact fieldpoint(cFP)

which IO server type should be used for building DSC application for compact fieldpoint target?
when i use my computer as target then i get various options for IO server type like custom VI,opc client,epics,data set marker,modbus.But when i choose compact fieldpoint as target i got only epics and modbus options.Is there any problem with my HW/SW or with my concept?
kindly clearify.....
regards
vks

Hi,
if you just wanna use Labview for logging and graphics (using Ethernet) AND you do NOT use a Real-Time cFP-Controller then you do not need Labview Real Time.
E.g. if you use NI cFP-1804 - Ethernet/Serial Interface for Compact FieldPoint.
(http://sine.ni.com/nips/cds/view/p/lang/en/nid/202527)
If you are using a Real Time Controller than you will NEED Labview Real-Time.
You cannot work without it!!!

Has anyone implemented a QUADRATURE IN / QUADRATURE OUT application using the Compact FieldPoint?

Has anyone implemented a QUADRATURE IN / QUADRATURE OUT application using the Compact FieldPoint? The units being used are the cFP-QUAD-510 [input] and the cFP-CTR-500 [output]. What I would like to do is use the QUAD-510 to capture a quadrature signal from a sensor, which in turn would generate a count per quadrature detection. Within LabVIEW, adjust the count received. Then, output a quadrature signal, based on the adjusted count, using The CTR-500.

Hello Andre,
Thanks for your response. That example does provide the output desired, and it is currently being use in my application, along with the 32-bit counter example available via NI for the QUAD-510, which also works. My query was mainly geared to find out if an application with the characteristics described in my original question has already been implemented, this, to avoid "re-inventing the wheel." Additional input on this thread is welcome and appreciated. Thanks.

Dag Gollopp
