VoltSE datable values

MHyatt Nov 17, 2025 08:51 PM

I am using a 3:1 voltage divider to allow reading of a 9 to15volt DC input to U2. (provides 3 to 5volts to U2).  The varible I use shows the correct scaled value.  VoltSe(POEV,1,mV5000,U2,False,500,5,Mult(2),Offs(2)) - this work fine.

For the data table I have:

DataTable(POEVout,True,-1)

DataInterval(0,10,Sec,2)

FieldNames("POEBV") 

Median(1,POEV,10,FP2,False)

EndTable

The issue is the value in the datatable rails at 7999mV, so I cannot capture any voltage over 8volts (which with a 3:1 divider is only 2.666v applied to U2.

thoughts?

I believe the issue is your data table. Change the output data type from FP2 to IEEE4.

Thanks, That was the issue, I figured it out after some additional reading and testing.
