Dear  All,
We have problems with FBM 214 all channels getting elevated 10 to 20 %  than
real field readings. FBM rev is 2.35F . By reinitialising the FBM gets  back
to normal readings and functions. Is any one facing similar  problems.



Please don't be offended if I mention a few things you may have  already 
checked.  This is obviously an FBM for Hart protocol devices (which  are 
inconvenient in Fox I/A anyway, requiring RIN and ROUT blocks for their  
accompanying 
AIN and AOUT blocks to have decent functionality).   Check that your MGAIN on 
the RINs are 1.0 and that your KSCALEs and BSCALEs on  your AIN blocks are, 
respectively, 1.0 and 0.  Make sure your SCIs on your  AIN blocks are 0.  
Finally, watch that filtering in the AIN  block (FLOP and FTIM) are not set too 
high.
