Rotary Enable

This parameter is used to enable the RotaryRolloverPosn for this PLS.

Rollover Point

This parameter is the absolute position of the first repeat position for this PLS. When enabled it causes the PLS to repeat every time this distance is passed. The repeating 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.
