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 motion-derivatives of the Motion-Dimension
STEP 1: Select the Data-Channel

STEP 1.Open the Statistics dialog To open the Statistics FB dialog
The Statistics FB dialog is now open. |

 Statistics FB dialog Channel / Derivative STEP 2.Click the Derivative drop-down and select the derivative for which you want Statistics
* 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 |

STEP 2: Show the Statistics Properties
 Statistic Properties dialog STEP 1.Open the Properties box
The Properties box is now open. Read the Statistical Properties for the Data-Channel of the wire that is connected to its input-connector.
