This function block allows for the editing of the profile and being able to assess the implications of the proposed changes ( including changing the number of segments of the profile ) before downloading all the parameters at once.</div> <bR> <DIV ALIGN="LEFT"></DIV> <div> <I><IMG SRC="1391f6c0.jpg" border=0 width="543" height="364" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></I></div> <bR> <bR> <div> <I><B>Profiler - Profiler Characteristic</B></I></div> <bR> <div> I am currently working on a Profiler block that has TIME as the X axis and multiple Y outputs.  This enables a number of different parameters to be profiled in time. This block is trying to be all things to all people and thus is very complicated to explain in a few simple lines. The X-axis is in the form HHHMMSS  ( H - Hour is the highest demonimator ) and can either be driven externally to this block or the block itself can generate it's own time function.</div> <bR> <div> There are so many different modes that it is a bit too confusing to describe all the modes - Best to just look at the graphics and ask questions later. </div> <bR> <div> <IMG SRC="114b71a0.jpg" border=0 width="695" height="538" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <bR> <div> Like a lot of the Function blocks that I develop they have an equivalent  <A NAME="linchr_excel"><IMG BORDER="0" SRC="1x1.gif" HEIGHT="1" ALIGN="bottom" WIDTH="1" HSPACE="0" VSPACE="0" ></A><FONT SIZE="3" COLOR="#0000FF" FACE="Arial" ><B>EXCEL</B></FONT> spreadsheet that can be used as the source of the information.</div> <bR> <div> <IMG SRC="13d3c690.jpg" border=0 width="1084" height="617" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <bR> <div> I am generating this block in my own time   but   realise now that had this block been available when I was working for Kelco during their fermenter profiling it would have made the control much easier and made all the bespoke graphics that I generated redundant.</div> <bR> </td> </tr></table></body>
