TMR : retentive timer

retentive timer store (retain) current value of timer when it reaches the preset value. if the retentive timer input set to true than timer start up and reaches to preset value if the current value is equal to preset value than timer retain or store accumulated value(current timer value). if the timer bit set you cannot run timer again because current value is equal to preset value if you want to run your timer again then first reset retentive timer . Accumulated value of a timer returns to 0 when the input conditions of the timer rung become false. This is not the case with retentive timers. To return a retentive timer accumulated value to 0 it is necessary to use the TRST T# instruction.
