Autotuning PID Online.VI Example Reads Proportional Gain 'NaN' with the Relay Technique.When running the Autotuning PID Online.vi example, with the Relay Technique the "Tuned PID gains" output of proportional gain (Kc) shows "NaN" when the program believes tuning is completed by flashing "tuning completed?". Workaround: Tune the individual terms first. Start by first tuning for P until the response is stable. Then continue to tune by switching to PI. Lastly, repeat the process for PID. |

Event Loop, In Place Element Structure, and Timed Loop do not create correctly when dragging from Right to Left (instead of Left to Right)There are some structures that do not create correctly when dragging from right to left (instead of left to right). The structure will create and expand in the Y-axis correctly but will stay to the right of the point where the mouse clicked before dragging, and remain in the smallest width possible. I expect all of them to expand in the X-axis to follow the mouse drag when moving to the left. Workaround: Create the structures left to right, instead of right to left. |
