range begins at an absolute position of zero and ends at the RotaryRolloverPosn.

For example, in a rotary application a PLS could be setup with an OnPosn of 90 degrees and an OffPosn of 100 degrees. If the RotaryRolloverPosn is set to 360 degrees the PLS would come on at 90, go off at 100, go on at 450 (360+90), go off at 460 (360+100), go on at 810 (2*360+90), go off at 820 (2*360+100), and continue repeating every 360 degrees forever.

This View allows the user to configure which parameters are saved when power is cycled. If a parameter is not in this list, the value of the parameter will revert back to the value that was downloaded when power is cycled. If a parameter is in the list, the value that was being used just before power is cycled will be used when power is restored.

7.3.12 Capture View

The Capture View allows the user to configure the various Capture object parameters. Figure 76 shows an example of the Capture view.

A detailed explanation of each of the Capture components is below.

Name - You can assign a descriptive name to each capture, making the configuration easier to follow. The length of the text string is limited by the column width with a maximum of 12 characters.

Simply double click on the Name field of any capture line to assign a name to it.

Capture Number - This parameter defines the number of Capture objects available. Maximum is eight.

The following four parameters are the data that is acquired by the position capture object. These parameters are available to be used as variables in a program. The four parameters can be accessed as follows:

Capture.#.CapturedTime - The time, in microseconds, from a free-running 32-bit binary counter at which the CaptureActivate signal activated.

Capture.#.CapturedPositionCommand - The command position, in user units, at the time when the CaptureActivate signal activated.

Capture.#.CapturedPositionFeedback - The feedback position, in user units, at the time when the CaptureActivate signal activated.

Capture.#.CapturedMasterPostion - The master axis feedback position, in master axis distance units, at the time when the CaptureActivate signal activated.

The captured data remains in these parameters until the capture component is reset and CaptureActivate is activated the next time. When the capture component is reset and CaptureActivate is activated, the data related to the previous capture will be over-written by the most recent capture data.
