F_BACnet_RealLT

Function for comparing two floating-point values taking into account the value range. This function should be used instead of the standard operators ("<" or "LT") for values from BACnet, since otherwise a PLC stop is triggered if the values to be compared are not in the finite range.

VAR_INPUT

fIn1         : REAL;
fIn2         : REAL;

Return value: TRUE = value 1 is smaller than value 2. FALSE = value 2 is greater or equal value 1, or one of the two values is not in the finite value range.
