Which of the following is NOT typically an integer value type in PLC systems?

In programmable logic controller (PLC) systems, data types are crucial for managing information efficiently. Each data type serves a specific purpose and has its characteristics. The integer value types, in particular, are essential for representing whole numbers without any fractional component.

The REAL data type is used for storing floating-point numbers, which can have a decimal component. This distinguishes it from integer data types such as INT, BYTE, and WORD that only represent whole numbers. In PLC applications, using REAL allows for more precision in calculations that involve fractions or require a broader range of values due to its ability to represent non-integer data.

The INT type typically represents standard integer values, BYTE is often used for smaller integer values (from 0 to 255), and WORD usually represents larger integers (from 0 to 65,535). Real numbers, by contrast, are used when calculations demand accuracy that includes decimal points, which is not the case for standard integer types. Thus, identifying REAL as not being an integer value type aligns perfectly with its intended use in PLC systems.
