Unable to maintain communication within the company Intranet

[Joseph_Loo]

I have been trying to maintain communication with a fieldpoint module on the company intranet. I have tried version 3.2 and 5.02 firmware version on a FP 1600. On version 5.02, communication last only about 10 minutes. With the 3.2 version, I can sometime maintain communication up to 3 hours.

The fieldpoint will loose communication and all the status light indicates that the device is working correctly except you can not communicate with it at all. The only way to start communication is to power off and power on the module. The program or Max can then restablish communication.

I tried to downgrade the fieldpoint to 3.2 but I keep getting a communication error whenever I try to dow an upgrade. This occurs
even if the unit is on a separate LAN. I have been able to determine if the the unit is on separate LAN, the unit will work for hours without a problem. It seems that when it goes on the intranet, the Fieldpoint unit will just freeze and die.

Joseph,

Have you tried removing the DNS server and gateway IP address settings from the Network Settings page in MAX? If these IP addresses do not exist then you can receive timeout errors or communication errors especially when trying to upgrade or downgrade firmware.

Regarding the general communication problems with the FP-1600, there are know issues with it. All of the know issues are fixed in the FP-1601 and latest firmware.

I have eliminated the DNS and gateway portion. It seems to have improved the time period to about 1/2 hour.

All of those address, DNS and gateway exists. Do you have a location that list these known issues with the FP1600?

Hello Joseph,


I will be taking your case from now on. I am going to try and replicate your issue and will let you know of any updates as I go along.

You can find problems and solutions with the FP 1600 by searching through our Knowlege Base. You can type any question you have on the search box at NI.com and see if there is a KB about that.

Please allow me a couple of days to try and reproduce your issue. I will be getting back to you shortly.
