Question 2

An SQO sequencer with a 48 bit word length is needed where data starts at N7:20, length is 12, and the least significant output bit is O:1.0/0. Which one of the following statements correctly describes the ladder logic and sequencer configuration used for this application?
 
  A) The three cascaded SQO sequencers would be placed on a single rung in series to link the three 16 bit outputs together.
  B) The three cascaded SQO sequencers on a single rung would have identical parameter values in the mask, control, length, and position elements. The starting field address for upper 16 bits would be N7:20, the middle 16 bits would be N7:35, and the lower 16 bits would be N7:50. The destination addresses from MSBs to LSBs would be O:1.0, O:2.0, and O:3.0.
  C) The three cascaded SQO sequencers on a single rung would have identical parameter values in the mask, control, length, and position elements. The starting field address for upper 16 bits would be N7:50, the middle 16 bits would be N7:35, and the lower 16 bits would be N7:20. The destination addresses from MSBs to LSBs would be O:3.0, O:2.0, and O:1.0.
  D) The three cascaded SQO sequencers on a single rung would have identical parameter values in the field, mask, destination, control, length, and position elements.
