I need to bind NV's from a 9000 via LonWorks to a controller.  The controllers that I use only accept 2-byte SNVT's yet the 9000-Lon puts out the data via 4-byte.  Any different SNVT's I try using skews my values.  For instance, I want to get nvoTotalVA (SNVT_power_f#US) bound to a controller.  When changed at the PT-9000 from power_f#US to power#US, the value is greatly different.  Is there any 2-byte SNVT I can change these XXX_f#US to so I can keep the values the same?

Henry,  I will have to dig into it a little further but I think that the PTNTL10 is only capable of  4-byte floating point output values.  Any change would reqire a code revision that we have never looked into.  How many would you need?
