What's the FBM partnr.

FBM's Eeprom level ....

2nd 

There is a small tool active hart where you can monitor the hart signal (if
you have a serial hart modem)

http://www.uuhome.de/Hart.Profibus/products.htm

If the signal get scrambled for a reason you can get the same result. Check
the channel LED's (for blinking) on the FBM or with above tool to check the
hart messages.

It doesn't upset your signal, it works like a hart handheld.

I keep these blocks in the same phase and period. 

That's what I would suggests to check.

Subject: [foxboro] RIN blocks from HART tertiary variable & fourth variables
keep smurfing/unsmurfing

Hi List, =20

Anyone using HART communications via RIN blocks in which the PNT_NO =3D = TV
(tertiary variable) or PNT_NO =3D FV (fourth variable)?  Both belong to the
same parent ECB201.  Please help. =20

We went for a really long stretch of NO SMURFs from 1/17/05 - 2/26/05.
Then on 2/26/05 then I "accidentally" clicked "DONE" in the ICC on the
parent ECB201.  Immediately the RIN blocks for TV and FV smurfed and began
repeatedly smurfing/unsmurfing.  Then miraculously unsmurfed for an entire
~48hours.  But as of this morning the the RIN blocks started repeatedly
smurfing & unsmurfing as frequently as every few seconds but some times only
every 5 - 10 minutes.

The period and phase are different for each RIN block. =20

Note that the primary variable of flow is being read as PNT_NO =3D current,
so there is no interruption in our process flow.  But our process is
considerably upset because we are using the TV and FV variables in enthalpy
calculations.

TAC is notified.  No resolution yet.  And we are very concerned about
our process.   Can anyone suggest how to troubleshoot why the digital
communication is not working?  The 4-20 signal is fine.  =20

THANKS VERY MUCH.
