If we are in online in function block value is showing in duble float point something like 1256.3
But same address in vat table it is showing 1258 or 1254
Why the value is varying from FB to VAR
Due to this reson we are unable to mesure actual value of tank levels
Program in lader logic and using mltiplcation block for caliculation and input is two wire 4 to 20 mA
