Statistics FB

Use a Statistics FB to summarize data-values over a machine-cycle - e.g. Minimum, Maximum, RMS, ... .

Compare with Element Properties dialog, which shows the data-values at the Master Machine Angle.

STEP 0: Add a Statistics FB and connect a wire to its input-connector.

After you add and connect a wire to a Stats FB, there are two steps you need to do to get Statistics for a Data-Channel on a wire.

STEP 1: Select the Data-Channel

STEP 1.Open the Statistics dialog

To open the Statistics dialog

1.Double-click the Statistics FB in the graphics-area

1.See How to Open a dialog

The Statistics dialog is now open.

STEP 2.Click the “Channel / Derivative” drop-down and select the derivative for which you want Statistics Properties

The Data-Channels in the drop-down box are always Dis., Vel., and Acc., even if the actual units of the data and data-channels are, for example, Force units.

Channel / Derivative	≡ Actual Data-Channel
Dis.	Linear or Angular Displacement; or Torque
Vel.	Linear or Angular Velocity; or Force X
Acc.	Linear or Angular Acceleration; or Force Y

Ignore the other separators in the dialog.

STEP 3.Click to close the Statistics dialog

STEP 2: Show the Statistics Properties

To open the Statistics dialog

1.CTRL + Click the Statistics FB in the graphics-area

2.Click Edit menu > Rebuild Now

If the Master Machine Angle changes, you must Rebuild Now, again.

Statistic Properties dialog

The Statistical dialog form is now open.

Read the Statistical Properties for the Data-Channel of the wire that is connected to its input-connector.
