Math and Data Move instructions are output instructions that will only execute if the rung they occupy is true. Is this statement true or false?

The statement is true because Math and Data Move instructions in programmable controller systems are designed to execute when the rung they are part of evaluates to true. In ladder logic programming, each rung typically represents a condition or a set of conditions that must be satisfied for the instructions within that rung to carry out their functions.

When the rung conditions are met (true), the Math and Data Move instructions will execute, performing the necessary calculations or data transfers. If the rung does not evaluate to true, these instructions will not run, effectively ensuring that operations occur only under specified conditions. This behavior is fundamental to how programmable controllers manage process control, allowing for precise and controlled execution of tasks based on real-time data and conditions.

Contextually, while the other options might suggest variations in operation, they do not apply to the fundamental operation of these instruction types within the ladder logic framework.
