Abstract: This control system includes: a first arithmetic unit for doing cyclic execution of a first task to which one or a plurality of processes are allocated using a first control cycle; and a second arithmetic unit for doing cyclic execution of a second task to which one or a plurality of processes are allocated using a second control cycle that is longer than the first control cycle. For the first task, a first data collection process with a first input data as the target and a corresponding first data processing process are allocated. Depending on the setting via the support device, a second data collection process with a second input data as the target and a corresponding second data processing process are allocated to either of the first task and the second task.

Abstract: Aspects of the subject disclosure may include, determining a twist number based on digital input data, wherein the twist number corresponds to a predetermined orbital angular momentum of a photon. An adjustment value is generated based on the twist number, and multiple orbital angular momentum modulators are adjusted, wherein the modulators are adapted to change orbital angular momenta of photons of an input optical beam according to the adjustment value. Application of a light beam to the multiple orbital angular momentum modulators applies orbital angular momenta to the input optical beam resulting in a modulated optical beam having a predetermined number of twists based on the predetermined orbital angular momentum. Other embodiments are disclosed.

Abstract: The subject matter disclosed herein describes a switch embedded in a motor controller and a network protocol executing on the switch to provide communication between devices connected to the motor controller in a motor drive application. The embedded switch is configured to communicate via separate ports with an external controller, a network interface for the motor controller, additional motor controllers, and with the motor or other devices mounted on the motor. The network protocol includes a first tier for data that requires deterministic delivery at a high data rate, a second tier for data that requires a high delivery rate but is also tolerant of some variation in delivery time, and a third tier for data that may be delivered at a slower data rate. The embedded switch receives data at any port, identifies the communication tier to which the data belongs, and delivers it to another port accordingly.
