Timers are __________
In word zero, of timer element, bit 13, is the _______
In an on-delay timer, the enable bit will be true when the timer-timing bit is true. Timer enable bit will be set through the transition from the timer-timing bit to the timer-done bit. Timer enable bit is set as long as there is logical continuity through all input instruction to the timer instruction, no matter the relationship between the preset value and accumulated value.
In timer element, word 0 is for ________
In timer file 11, timer 6's timer enable bit is addressed as _______
___________ instruction is used to program a time delay to begin after rung input goes false.
