Retentive Timer On. This article discusses about retentive on delay timer instruction and working principle using allen bradley programmable logic controller (plc) ladder logic. The rto, also know as retentive timer, an instruction is used to keep track of time just like the ton instruction. A retentive timer can be built with an on timer and supporting logic. The timer is a fundamental function of ladder logic programming. A typical ton implementation automatically clears the accumulating value when its input goes false. However, there is a key. Each type uses its time delay and triggers its output in a specific way. An rto (retentive timer on) timer in a plc is a timer that retains its accumulated value during power interruptions or when the. The most common application of plc timer types are the on delay plc timer, off delay plc timer, retentive plc timer and pulse plc timer. Plc timers are generally used for delaying an event from taking place, or to delay a device from shutting off either on an on transition or an off transition. That is, when its rung condition changes from true to false, the timer simply stops timing, but its accumulate.
