Which one of the following troubleshooting techniques is NOT useful for sequencer problems?
 
  A) When troubleshooting a sequencer problem with a large database having many elements, start with just a small data set.
  B) If an SQO instruction is used with a timed input, then replace the timed input with a manual switch or forced input instruction to manually step through the sequencer file while all the sequencer outputs and machine actions are verified.
  C) Verify the instruction parameters, especially the length value.
  D) In applications where the sequencer instruction is false during the first PLC scan, verify the 0 position was included in the length value.

Question 2

Which one of the following troubleshooting techniques is NOT useful for sequencer problems?

  B) Check for incorrect parameter data in all sequencer instruction parameters.
  C) Check for incorrect data in sequencer data files.
  D) Check all sensors for proper input level when activated since input bits are compared to sequence word tables in SQI sequencers.
