Setting Up Parameters
PLS View
The PLS View allows users to define Programmable Limit Switches (PLS) for advanced machine operation.
By selecting PLS in the Hierarchy View, the PLS View will appear on the right (see Figure 38).
Figure 38: | PLS View |
A PLS can be used to turn on or off a bit based on feedback position, commanded position, or master feedback position. Eight global PLS’s are available for a single application. To operate a PLS, first it must be enabled (see the PLS enable destinations in the assignments view) and then the Absolute Position Valid source must be active. Each PLS has its own OnPoint and Off Point, as well as a Rollover Point.
The terms OnPoint and Off Point assume movement in the positive direction. Those labels should be reversed if traveling in the negative direction.
