Statistics FB

See Add 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.


There are two steps you need to do to get Statistics for a Data-Channel on a wire.

STEP 0: Connect a wire to the input of the Statistics FB.

A wire that you connect from the output-connector of a FB to the input-connector of the Statistics FB has three Data-Channels.

For example, the three Data-Channels at the output-connector of a Motion-Dimension FB are the three linear or angular motion-derivatives of the Motion-Dimension

STEP 1: Select the Data-Channel

STEP 1.Open the Statistics dialog

To open the Statistics FB dialog

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

OR

1.See How to Open a dialog

The Statistics FB dialog 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 Displacement or Angular Displacement; or Torque

Vel.

Linear Velocity or Angular Velocity; or Force X

Acc.

Linear Acceleration or Angular Acceleration; 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 OK-tiny-13-17 to close the Statistics dialog

STEP 2: Show the Statistics Properties
