Note Using the Reset instruction with timer instructions The TONR timer can only be reset with the Reset (R) instruction. The TON and TOF timers can be reset by the timer's enable input and also the Reset (R)instruction. The Reset instruction performs the following actions: • Timer bit = OFF • Timer current value = 0 • After a ... TON (Functionblock) The TON function block is an ON delay timer that enables the "q" output a specific number of milliseconds after the trig input is enabled. When the trig input is set TRUE, the elapsed time counter (et) is reset to zero and then incremented until the preset timer value (pt) is reached, after which the "q" output is set TRUE. Time in PLC programs is used almost everywhere from delaying the start of a motor to prolonging a signal. PLC timers are used exactly for that. Although they at first can seem confusing it doesn't take a lot to understand how they work and how to use them. Content: On Delay Timer (TON) Off Delay Timer (TOF) Pulse Timer (TP) Timer AccuracyToF – Direct vs Indirect • Two ways to measure the Time of Flight (ToF): • In the direct method, the time difference between the emitted pulse, and a received signal. • In indirect, a continuous modulated sinusoidal light wave is emitted and the phase difference between outgoing and incoming signals is measured.

Those of us who've been programming Allen-Bradley PLCs for some time now have found many uses for the TON and TOF Ladder instructions. And I'd also wager many of us have found more than one way to implement our own On / Off code as well. between the PLC and the original timer circuits. Allen-Bradley provides three timers; TON, TOF, and RTO. All are block-type instructions and are located at the extreme right of each rung used. They are parallel to coils but may not be used in series with each other or in parallel with coils. Each has two coils extending from its right. The instantaneous contacts of a timer have no time-delay period associated with them. T The accumulated time of a TOF timer is reset by causing the ring to go true momentarily F A RES (reset) instruction must be used zero the accumulated value in an RTO timer.
