MC_DigitalCamSwitch
This function block implements a digital cam switch. Depending on the data source (e.g. from a physical encoder), the cam switch can be used to control actuators (e.g. glue nozzles) in a dynamic motion sequence within adjustable limits or a value range (electronic cam). Any number of cam tracks can be used. Each track can consist of several cams. The switching signal is defined by a binary signal and a switching time.
