Configuration of a FF sensor

[Hzino]

we are having some problems with the configuration of FF devices with the NI-FBus configurator.

All the devices in the network shows the folowing alarm msg: UKN, but there is comunication and I can read values from those devices.
There is on special instrument, it's a level sensor that shows the following msg in the Resource Block:DSNF(Dict string not found), and no reading is done from the network.
The instrument itself don't show any error msg.

I guess you mean "all the blocks of the devices in the network" show msg: UKN. If so, it is a problem of your DD (Device Description) settings, please check whether your DD dictionary files exist (files like "nifb.dct", "nifb.ffo" or "nifb.sym" under ".\Nifbus\Data" directory). If not, you need to re-install NI-FBUS Configurator software to solve the problem.

On the other hand, the msg of "DSNF" might be related to DD Support libary, please upgrade your Configurator to version 2.3.6, which contains the latest DD Support library. Please refer to URL below:

You can contact "fieldbus.support@ni.com" if you have other question.

Well, it looks like the problem is the DD, however, it no necessary reinstal NI-FBus Configurator, only check the path for DD configured in the NIFBusConfig is the same wehere you had downloaded or unzipped your DDs.

If the problem continues, check the DD revision is the same of the hardware instruments (Check Foundation fieldbus web site or vendor web site to download dd).

Try commisioning and decomissioning the sensor before check the above points.

If problem continues, try restarting the power of sensor (Previously decomissioned).

Regards.

jcano is right, it is not necessary to reinstall NI-FBUS Configurator software.

The string "UNK" stands for "Unknow", which means the right DD files are not imported properly, so please

check the Resource Block of your device, open "Diagnostics" tab and check the parameters of

"MANUFAC_ID", "DEV_TYPE", "DEV_REV" and "DD_REV", which specify the DD files. Specially the

"DEV_REV" and "DD_REV" specify the DD file name, for example, if DEV_REV is 2 and DD_REV is 1, then

the DD file names should be "0201.ffo" and "0201.sym". Then you can find the correct DD files according to its

manufactor, device type(model) and the DD file name.

The string "SNF" indicates the standard dictionary files might be out-of-date, thus the new block types can not

be recognized. In that case, probably you need to upgrade your Configurator software to newer version. Or your

can copy the new version of "nifb.dct", "nifb.ffo" and "nifb.sym" to replace the old files in "..\NI-FBUS\Data"

directory, it might help as well.

If all of the blocks show "UNK", probably the standard dictionary files are missing, you need to copy those files

back the folder of "..\NI-FBUS\Data" for recovery.
