The document discusses mathematical operations in SIMATIC S7 and their usage. It aims to understand math operations and how to use them in different programming languages. It shows the symbols and functions for addition, subtraction, division, and multiplication and explains that the instruction is executed when EN is high and reads the first and second inputs to perform the operation, storing the result at the output address.

Mathematical Operation
EN The instruction is executed if RLO is =1 at Enable input EN.
IN1, IN2 The value at IN1 is read in as the first address and the value at IN2 as the second.
OUT The result of the mathematical operation is stored at the address at output OUT.
