And it's usually written on the timer instruction, what type of … WebOct 15, 2024 · Popular answers (1) TON and TOF are terms used in catalysis, respectively "Turn Over Number" and "Turn Over Frequency". They indicate the maximum number of conversions per unit of catalyst …
WebTOF (Timer OFF Delay) The TOF timer starts running when there is a negative edge at the timer input signal. It starts counting when the Enable(EN) bit is OFF and stops when the accumulated value is reached or when the Enable(EN) bit is ON. The Enable(EN) and Done(DN) bits work the same as the TON timer block. WebMay 4, 2016 · These observations are also evident from the corresponding turnover numbers (TON) and the turnover frequency (TOF), which are summarized in Table 4. TON describes the amount of triiodide which can be generated with the chosen porphyrin concentration. TOF is the turnover per time. The catalytic activity of TMPyP diacid-PSS …
By comparison, TOF instruction works much differently. When the TOF instruction goes true, the DN (Done) bit goes true instantly. After the TOF goes false, the DN bit shuts off later. Let’s take a look at a TOF instruction in logic. In this example, we have a Main Motor and a Blower Motor. When the Main Motor is … See more There are several TON and TOF Differences that you need to be aware of. In summary, the TON delays the DN bit from turning ON. The TOF Instruction delays the DN Bit … See more By far, the TON instruction is probably the most widely used instruction. It is also the easiest to understand. As an illustration, here is what the TON Instruction looks like in ladder logic. When … See more Use the TON when you need to delay an event from starting.
