What can Sources A and B of the DIV instruction contain?

The DIV instruction in programmable controller systems is used for division operations, where the instruction divides one value by another. Sources A and B in this instruction can indeed contain tags or constants. Tags refer to variables that are defined within the program, which can store dynamic data, while constants are fixed values that do not change during program execution.

When using the DIV instruction, providing flexibility in the types of inputs allows for a wider range of calculations. For example, if Source A is a tag (a variable that stores a value from a sensor) and Source B is a constant (a predetermined value), the instruction can be executed successfully. This versatility is crucial for effectively programming controllers, especially in applications where inputs may vary.

Since both tags and constants can be utilized in this context, it confirms that the choice stating that Sources A and B can contain tags or constants is accurate. This understanding enables programmers to write more adaptable and robust code, enhancing the performance of the programmable controller systems.
