June 16, 2025 - For example: a += b += c *= d; This is evaluated from right to left and is equivalent to: c := c * d; b := b + c; a := a + b; Such expressions must be written with caution, ensuring proper understanding of operation order and data types.

June 11, 2025 - In Siemens SCL (Structured Control Language), the power operator ( ** ) is used to raise a number to the power of another number. It is similar to the mathematical exponentiation operation. The power operator works with both integer and floating-point numbers, and the result is typically a floating-point value. This is useful in calculations involving areas, volumes, scaling, and more in industrial automation. In this example, a value is raised to the fourth power:
