Example 1: Cascaded Function Block Usage
The figure below shows an example where the Function Blocks controls “AxisX" with three different velocities. In a Ladder Diagram program, the velocities 10, 20, and 0 are assigned to the Velocity Input of the Function Blocks. To trigger the Execute input of Function Blocks 2 and 3, the variables L and M are used.
