Using Real-Time Java for Industrial Control

This compelling video, presented by Randy Rorden, Dir. of Software Development at PTC, shows how Java can be used for real-time IoT edge applications requiring deterministic behavior. The demonstration includes a simulated industrial sorter application with millisecond timing deadlines, written in Java, and running via the PTC Perc real-time Virtual Machine technology. PTC Perc is deployed in many real-world applications requiring sub-millisecond deadline response.
