CFp-1808 IP address

I am trying to setup a cFP-1808 and in Max (5.0.0f1) am getting to the screen that needs me to put in the device IP. What is the device IP or where would I find that? I will be using LabView2011 on a XP computer.
Thanks
Gerald

The Windows firewall was blocking the 0.0.0.0 IP address for the initial setup.
Turned off the firewall and the Field point cFP-1808 popped right up turned the firewall back on it is seems to be there.
Now it has been a long time since I worked with field point but the Field Point tool pallet does not show up and the Field point does not show up in the start: Program: National Instruments menu. I will ask that question in the LabView part of the forum.
Thanks
Gerald

CFP-1808 shared variables timestamp

Hi,
I need to control and acquire data from a cFP Ethernet module (cFP-1808) to a PXI RT system. I have tested two ways of doing it:
1. Bind shared variables to the Fieldpoint channels. Works great except for the fact that I have to record the timestamp of every single channel in all Fieldpoint modules. I have to avoid this. The reason I have to record all timestamps is that sometimes two consecutive reads are the same in value and in timestamp; so even if I make sure I get a value every 100ms in my real time application I cannot trust that the shared variable engine will give a real new value every 100ms, because sometimes one read is the same as the previous one. My
understanding of the technology is that the cFP network interface checks for an
updated value of the channels of each module at the Advise Rate. If there’s a
new value the cFP transmits it to the Shared Variable Engine running in the PXI
controller, but if the value has not changed it doesn’t transmit anything, so
more efficiency is achieved in the network communication. This would explain the
timestamp behavior of the shared variables bound directly to Fieldpoint
channels; since there is no new value the shared variable is not updated so the
timestamp of two consecutive reads is the same.
2. Create a Modbus server and then create shared variables bound to the Modbus server channels. With this method any time my RT application asks for a new value the shared variable engine provides a real new value with an updated timestamp, and all timestamps in the same module are equivalent (in 1usec range). Therefore, it looks like using the Modbus solution I only have to record one timestamp per module.
So option 2 probably fixes my problem, but I'd like to understand why. Both methods use the shared variable engine, shouldn't they behave the same way? There's one downside in option 2, which is having to deal with Modbus addresses and not having the ease of use of option 1 that just browses to find the Fieldpoint channel.
Any comments?
A final note, it'd be great to be able to use the Fieldpoint VIs in LV Real-Time! Can this be achieved?

Hi Raimon,
How are you binding to your shared variables? This KB reviews three methods:
http://digital.ni.com/public.nsf/allkb/FA610367EC62574186257118005089F2?OpenDocument
I don't believe using FieldPoint VIs on a PXI RT target is possible because FieldPoint is not a driver that you are able to install on the PXI RT target. We do have the cFP-2xxx line of RT controllers for FieldPoint, which can communicate directly to the FieldPoint modules, ensuring determinism.

CFP 1808 can not see software option under tree in MAX

I have configured the cFP 1808 with the correct IP address so that it is recognized by the laptop but when I expand the tree under the Field Point there is no options under it. I need to install Real-Time software but obviously can't if the option is not given to me.

The cFP-180x are just distributed I/O interfaces for ethernet or RS-232. The do not have an on-board host processor to execute an operating system like RT.

Getting cFP-1808 Data to cFP-2120 Controller

Hello,
We have an existing cFP-2120 Controller with the following embedded system software. We are on LabView 7.1.1 on the Windows Host.
LabView Realtime
7.1
NI-Watchdog
2.1.2
NI-VISA
3.2
NI-Serial RT
2.5.4
NI-IrDA RT
1.0.1
Datsocket for LabView Realtime
4.2
FieldPoint Drivers
5.1.0
FieldPoint VI Manager
3.1.0
We have purchased a cFP-1808 Ethernet/Serial backplane and additional I/O modules to extend the I/O on this system (as the I/O on the existing controller's 8-slot backplane is already full with 3 AI-111, 3-DI-301 and 2-RLY-420 modules). We were told and I have seen documents that suggest that we should be able to read data from the cFP-1808 on the cFP-2120.
Unfortunately, however, we can only read data on the first module (an AI-111) and up to the second module's channel 11 (a DI-301). The data reads fine within NiMAX, but not from the controller. No channels after that channel can be read either. The module has been swapped and the backplane swapped as well.
The cFP-1808 is on the same subnet, etc. The Ethernet info is:
cFP-2120 Controller, 10.0.0.242
cFP-1808 Backplane, 10.0.0.142
Subnet Mask(s) 255.255.255.0
As I said, some of the data can be read up to a certain channel and the I/O data can be read within MAX. So, it's not really an Ethernet config issue. So please, *no replies on the Ethernet config* or hardware setup.
We are also trying the Optomux (extended) Commands via the serial connection (direct via null modem cable), but have not had much luck there either.
If we can not extend the I/O in this way, then how else would be with such an existing controller?
Thanks,

Please allow me to answer my own post here.
We were able to read data on modules residing on a cFP-1808 I/O backplane from a cFP-2120 controller. This was done using "logos" protocol and the Datasockets functions. The format of the URL is as such
logos://10.0.0.10/FP/4DI/12
where,
10.0.0.10 is the configured IP address of the cFP-1808
FP is constant for FieldPoint
4 refers to the number "4" module in the bank
DI is a designation of a digital input module (in our case a DI-301 module), and
12 is the number "12" input channel
We were under the incorrect impression that Datasockets could not be used on an embedded/controller system. To the contrary, this does work.
There are recent documents released by Idaho National Labs and other government studies in SCADA security that suggest that the Datasockets protocol is not secure. Therefore, we have made some reassurances by isolating this communication behind a firewall. Only a single Windows XP host can communicate with the network segment which contains both the cFP-2120 controller and the cFP-1808 I/O backplane.
We were never able to get the Extended Optomux functions to work between cFP-2120 controller and cFP-1808 I/O backplane (using respective serial ports and null modem adapter). This would be a secured method as well, if it could be made to work.

Daisy Chain cFP-1808 Network interface module

Hello,
I am trying to find some documententaion that explains how to Daisy Chain 2 NI cFP-1808, which is Network interface modules for the Compact Fieldpoint platform. http://sine.ni.com/nips/cds/view/p/lang/en/nid/202210
I am also trying to find out what are the performance hits when adding 1 or more cFP-1808 to a system.
Also has anybody had experience doing this and what did you observe?
Thanks
Dan

Use an ethernet switch to connect as much as you want.
The filedpoint system is low-speed I/O with 10Mbit ethernet you should see no performance hit imho.

Can you please tell me in detail how to connect a CFP-1808 and a CFP-RLY-425 with a ethernet conection to the labview please

Hi,
I am doing a research in creating a controlled environment, and i require using labview and NI equipment to control the environment. I am currently using a CFP-1808 as a bank, and using a relay module to connect it to the labview software.
Can you give me detailed information on how i will be able to do that.
regards,
Robert

Hi Robert,
Have you had an opportunity to take a look at the cFP-1808 Quick Start Guide? And the Operating Instructions for the cFP-RLY-425? Also the Compact FieldPoint FAQ is an excellent resource.
Hopefully those can get you on your way,

How to build a current loop with cFP-1808 and analog input module AI-110?

I am trying to build a current loop to measure temperature via and a resistance thermometer a transmitter that converts the signal to current. I am using cFP-1808 with the power supply PS-5 directly connected to it.
For the current measurement I am using AI-110 but I am having trouble with getting current in my loop. I have looked in he manual of the AI-110 module and am using the set up for a "loop with an external power supply", counting the PS-5 as external. That is to say, I have connected the negative transmitter terminal to Vsup on the AI-110, and the positive side to Vin. Now, however, I am stuck. I don't get any signal in my loop.
Can I use the PS-5 to power my AI-110 module or do I need to use another external power supply? In this case, how do I connect this?
Thanks for any help!

Clara G:
I overlooked that in your 1st post you were connecting the other end of the transmitter to Vin, you actually need to connect it to Iin on the AI-110.
Regarding the use of the PS-5 to power the cFp and supply power to the loop, I do not know if that will work or not.
Suggest that you switch over to Iin terminal and use the separate 24V supply to power the loop. If that works, them maybe try the PS-5 for both the cFP and loop power.

RS 232 port to communicate between cFP 2100 and Multiple cFP 1808

Hello All,
I am using one cFP-2100 (controller) and two cFP-1808 (network contoller) for a project.
All the three devices have Ethernet port, so i can connect to a network switch for communicating with the Host PC.
My question is:
All the three devices have Serial Ports (RS 232) too, Can i use those ports to communicate between the three devices (1 controller and 2 Net. controllers) and use the ethernet port in the controller (2100) only for communicating with a Host PC?
If this is possible, how to do the RS 232 cabling ?
Regards
John

Hi bjsprem,
You can connect network modules to the controller with serial. This KB shows how to do this. Hope this helps!

Curently using LabView 2013 is there anyway to use cFP-1808 with this version LabView?

How can I use older hardware that 2013 doen't support without uninstalling 2013 and going back to a version that does support it? I'm starting to wonder why upgrade when it will obsolete hardware you already own, Previous upgrades still showed older versions of LabView but 2013 doesn't.

Hello Rod,
If you install LabVIEW 2013 and FieldPoint driver 6.1, you should be able to add a cFP-1808 to your LabVIEW project. Did you reinstall drivers after upgrading to 2013? If you don't do this, cFP support won't be added to LabVIEW. Are you getting another error or warning when trying to recognize the target from LabVIEW?

Communicating with cFP 1808

How can I communicate from a vi running embaded on cFP 2020 to data chanels from cFP 1808 module. I am using LabVIEW and RT module 7.1 ver.

Hello dksharma,
This is Dominic L. from Applications Engineering at National Instruments. How would you like to communicate between the cFP-2020 and cFP-1808 module? Two methods of communication can be used: ethernet or serial. I would recommend using ethernet simply because it is faster. Once deciding to use ethernet, you can choose a protocol: OPC, FieldPoint API/driver, or Modbus. I believe Modbus is the fastest protocol. To help you get started you can search the discussion forum for more information on FieldPoint and Modbus.
The cFP-1808 module requires FieldPoint 4.1.2 or later. If possible, I would work with FieldPoint 5 because that would allow you to use simple FP-read and FP-write VIs rather than making your 1808 a Modbus slave (with older drivers).

Transfer cFP 1808 bank to delivery computer

I have a cFP setup working fine in LV 2010 on my development computer. Now I need to move it to a delivery computer. I copied all the project including the.iak to the (shiny) new computer which has LV and PF and Visa etc all freshly installed and apparently working.
I connect the ethernet cable and MAX does not see this bank of cFP. It will not recognize the IP address (192.168.1.2) the computer IP is 192.168.1.109.
The Ethernet port works because when I connect it to the modem, my network name shows up.
The cable works because it works on my development computer
I get error 32812 when I try to read one of the TC modules.
Any help will be gratefully received.
John

Hi jbrohan,
In order to switch the FieldPoint to the delivery computer, you will need to make sure the FieldPoint drivers are installed on the new computer. Also, you will need to set up the computer's network settings according to this KB. Once you do this, you should be able to locate the FieldPoint. If you still can't see the device, try to ping it using the IP address and the windows command prompt. If you cannot ping the device, than that usually means there is something wrong with the network settings.
Do you have multiple networks cards on the delivery computer? If you do, you may want to refer to this KB.
Hope this helps!

Retrieving cFP's IP address

Hi,
From my embedded LabVIEW, I would like to retrieve the IP address of the cFP controller it is running on. How can I do this?
I can easily do this from my Host by using the Ping Controllers.VI. But I would like to do this on the RT target (Ping Controllers.VI did not work -- timed out -- when embedded). Something similar to the IPCONFIG command, but for RT, would work.
Thanks in advance!
-Khalid

Another way of doing this on a PC is using String to IP followed by IP to String (both from the TCP palette) with Dot Notation set to True.
I can't test this on a FP at the moment, but I think it will work.

How to get the cFP IP Address?

Hi, I have a VI running standalone at a cFP 2020, and I can access the front panel using webserver. But to access these VI, I need to know the cFP 2020 IP address. This way, I'm leaving a fixed IP Adress. Now I want to put this cFP inside the company net, and, to do this, I'll select the "Obtain IP address from DHCP server" from the IP settings. But, doing it, if I know the cFP controller name, there's a way to discover the IP address?

Try using String to IP followed by IP to String (and select dot notation). I believe the name should be resolved correctly.
