This comparison function compares the operands connected to the input parameters in regard to less. Comparison proceeds from left to right. The function is available as standard function LT and safety-related function LT_S.
NOTE:
The comparison is always a signed comparison. Therefore the values for DWORD are limited to 31 bits, for WORD to 15 bits and for BYTE to 7 bits.
