Statistics FB

If you can connect a wire to a Graph FB to plot its data over a complete machine-cycle ...

... then you can connect a wire to a Statistics FB to find statistical data for the complete machine-cycle.

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

STEP 1: Select the Data-Channel

STEP 1.Open the Statistics dialog-box

Edit the Statistics FB:

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

- or -

The Statistics FB dialog-box is now open.

Channel / Derivative

STEP 2.Click the Derivative drop-down and select the derivative for which you want Statistics

Derivative	≡ Data-Channel
Dis	Linear Pos or Angular Ang or Torque
Vel	Linear Vel or Angular Vel or Force X
Acc	Linear Acc or Angular Acc or Force Y

* The Data-Channels in the drop-down box are always: Dis, Vel, and Acc , even if the actual units are different. The actual units:

•For a Kinematic-FB are three(3) motion-derivatives

•For a Force-Data FB are Total Force/Torque, Force X, Force Y.

Ignore the other separators in the dialog.

STEP 3.Click to close the Statistics dialog-box

STEP 2: Show the Statistics Properties

Statistic Properties dialog

STEP 1.Open the Statistical Properties box

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

The Statistical Properties box is now open.

Read the Statistics for the Data-Channel of the wire connected to its input-connector.
