What does the DOUT instruction with an OT#() tag operate?

• A. It reads an output status.
• B. It turns ON or OFF an output device, such as a light, clamp, or gripper; the output remains ON until OFF.
• C. It configures a timer for an output.
• D. It resets all outputs to a default state.

Answer: (B)

Controlling a digital output as a latched on/off state. DOUT drives a specified output point to on or off, and the OT#() tag makes that state persist until you explicitly change it again. In other words, once you turn the output on (or off) with this tag, it stays in that state across subsequent program steps until another command turns it off. This is ideal for devices like lights, clamps, or grippers that need to remain energized beyond a single execution cycle. It’s not about reading an output, not a timer setup, and not a global reset—the OT tag simply enables a persistent output state.
