Which of the following statements correctly describes how the SQO sequences response to the first two scans of the processor?
A) If the rung is true at the time of the first scan and the position parameter is 0, then the data in the memory location at position 0 is NOT transferred to the destination register and the position pointer is NOT incremented. B) If the rung is false at the time of the first scan and the position parameter is 0, then the data in the memory location at position 0 is transferred through the mask to the destination register and the position pointer is incremented by 1. C) When the processor is first changed from the program to the run mode, the operation of the SQO instruction is dependent upon the condition of the rung (true or false) at the time of the first scan. D) After the first scan the sequencer operation is triggered by a false condition on the ladder rung.
