Use other structured text programming to achieve the same result. See the description for the instruction.(2) There is no equivalent structured text instruction. Use the operator in an expression.You can compare values of different data types, such as floating pointand integer.For relay ladder instructions, bold data types indicate optimal datatypes. An instruction executes faster and requires less memory if allthe operands of the instruction use the same optimal data type,typically DINT or REAL.Publication 1756-RM003I-EN-P - January 2007
