The Robotics_Trigger.project sample project described here is located in the installation directory of CODESYS under ..\CODESYS SoftMotion\Examples.
Triggers are used to find out exactly when an axis group reaches a specific point on the commanded path. This information can be used, for example, to switch a tool on or off at exactly the right time. This example shows how a single trigger is commanded on a movement and then read out cyclically. Based on this, the Trigger Example 2: Gluing Process project shows a realistic sample application.
