What does TON mean?

The correct interpretation of "TON" is "Timer On Delay." This term refers to a specific type of timer used in control systems, particularly in programming logic controllers (PLCs) and automation. A Timer On Delay operates by starting a timer when the input condition is satisfied, and it delays the output for a predetermined time period before turning it on. This function is critical in various applications where a delay is needed to ensure that certain conditions are met before the output is activated, thereby helping to prevent premature actions and ensuring system reliability.

Understanding this concept is fundamental for those working in automation and control systems, as it allows for better programming and control over processes that require timing considerations. Through the effective use of the Timer On Delay, engineers can design systems that operate more smoothly and efficiently.
