Quizplus · Accepted Answer

A RTO retentive on-delay timer retains its accumulated value even if the rung goes false, the processor is placed in the program mode, or power to the processor is temporarily interrupted. This is because the RTO timer is a retentive timer, which means that it will continue to hold its accumulated value during these events and resume timing when the conditions are met again.
