Outlet Power Scaling with Compact Fieldpoint

Does anyone have any suggestions on scaling outlet power? I have a fan which takes 115 VAC and .68 A but the PWM module can't handle that wattage. I've considered using an electronic potentiometer but have yet to find one which suppports my requirements. It's for a fan which we need to scale between 0 and full speed.
We have:
Compact Fieldpoint 2120
cFP-AI-112 Aanalog input
cFP-PWM-520 Pulse width modulation output
cFP-TC-120 Thermocouple module

You may want to look for a small variable frequency drive. Speed is varied by different frequency outputs. You could control one by outputing an analog signal to it, or even using serial communication.

Gains Available with Compact FieldPoint

What gains are available with Compact FieldPoint
I/O modules?

This question does not really apply to FieldPoint/Compact FieldPoint. Different FieldPoint modules have different input ranges. By changing the range of a channel, the gain may be adjusted automatically. A user has no direct control over the gain. FieldPoint and Compact FieldPoint IO Modules have input ranges from +/- 25 mV to +/- 120 Volts depending upon the module. What sort of signal ranges are you looking for?

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!

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,
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:

Number of outputs in Compact Fieldpoint

Hello, all.
My name is Ng Oon-Ee, and I'm a student of Monash University Malaysia. I'm currently working with NI LabVIEW, utilizing Compact Fieldpoint. I have a simple question that I haven't been able to solve using either the forum search feature or through reading the documentation I have.
How many outputs are possible with Compact Fieldpoint (maximum number), also, how many outputs are there per module.
Thank you for answering what is probably a very inane question to most here.

Each Compact FieldPoint Controller have have an 8 slot backplane, allowing up to 8 IO modules. The IO modules range from 4 to 16 channels each. Thus, you can have up to 128 IO module channels per controller. Additionally, the controllers have 4 User accessible LEDs and 5 digital lines for an extra 9 channels.
Compact FieldPoint controllers can communicate with each other, so you can have an embedded program in one controller that is controlling the IO on other controllers to get additional IO.

Aaron

HT4060 Hi, I have bought iPad air, and got apple 12w USB Power Adapter with pin flat plug. It is a problem for me. I live in Switzerland and the electric outlet is suitable only for round pin plug.

Can compact fieldpoint work together with regular fieldpoint?

Hi,
I'm using regular FieldPoint modules with Labview 8.5 right now. I want to add new modules, can I choose compact FieldPoint moudles?
Thanks!
Gman

You'll have to get a new backplane and a new controller or network module. Compact Fieldpoint modules aren't physically compatible with the regular field point modules. So the new devices will show up as a new target in MAX. Beyond that, LabVIEW will be able to work with both just have in any application that would have multiple targets.

Compact Fieldpoint Reliability

Hi,
Up until today I was convinced that Compact Fieldpoint was the way to go on our new plant but I have read several posts on this forum about loosing network connections to the units and other horror stories which make me wonder about their reliability in the real world. Like most people we simply cannot afford to have to reboot occasionally, this is unacceptable.
Does anyone have any experiences, good or bad with running a Compact Fieldpoint system for long periods (months/years)?
Thanks
Tony

Tony,
Been running one cFP-2020 for over a year now. Have not had to reboot. Unit operates in a large test lab with multiple variable frequency drives and other tests that generate a lot of electrical noise. 3 more systems in the cue that will use cFP for long term testing. I did have one cFP-2120 fail after one day on the bench. Caused by failure of switching power supply in the controller. Unit was repaired and no further problems 1 year after repair.
The only other problems I've seen were self inflicted and fixed during development.

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:

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.

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.

Are there any relay modules available for Compact Fieldpoint, and if not, what are the alternatives?

I'm speccing out a Fieldpoint system, and although Compact Fieldpoint has many features that make it superior to Fieldpoint for my application, I'm wondering why no relay modules seem to be available for it.
The cFP-RLY-420 is referenced in the manual it shares with the FP-RLY-420, and a search in the product section comes up with several pages that aren't viewable, but it doesn't seem to be currently available.
More importantly, if there are no relay modules available at this time, what would be the alternatives for switching? A small Opto22 backplane wired to a DO module perhaps?

Mako,
Several of the more specialized modules in FieldPoint have not yet been released in Compact FieldPoint. However, National Instruments is presently working on releasing most of these traditional FieldPoint module in the future.
Depending on your application, either the cFP-DO-401 or cFP-DO-410 (which are both providing sourcing outputs) may be a possible alternative. The DO-401 module can sustain up to 2 A per channel, 8 A squared per module whereas the DO-410 can sustain up to 1 A per channel. Please note that these modules only handle low voltage DC.

Selecting and running vi's on a compact FieldPoint 2120 via remote panel

Hi,
I'm trying to provide two html files to run two different vi's on a compact fieldpoint. I can run either of them by setting them as 'run as startup' in the Build Specification which creates the startup.rtexe program on the controller but the only way I can run two different vi's on the fieldpoint is by renaming the files in the startup directory before calling the html file (and that doesn't work that well). Is there a better process to allow different programs to be run on the compact fieldpoint via the remote panel/html calls?
thanks

Hey AgB2,
I think the best way to get multiple HTMLs linked to their respective VIs would be to set your VIs as the Startup VIs when you build the EXE to deploy to your Compact Fieldpoint. A KnowledgeBase article describing the steps to do this can be found here:
http://digital.ni.com/public.nsf/allkb/466EA9705F98E07786257687005E081B?OpenDocument
Next, all you'll need to do to get your two HTML files to run two different VIs will be these steps:
1.Build the HTML for each VI you want to control
2. Enable the WebServer for your cFP
3. FTP your HTML files to the www folder on your cFP
Once you restart the cFP, your EXE will run at startup with both VIs and you can access them by navigating to http://<ip address>/<vi name>.html. Just to double check, I did this on my computer and had no problem loading both HTMLs or taking control of both VIs at the same time.

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.
