Product Release Notice: KINGSTAR 3.2

General Availability Release Date November 3, 2017

KINGSTAR products are designed for industrial machines requiring motion control and positioning systems. KINGSTAR’s all-software approach sets it apart from other machine control solutions.

Using the EtherCAT standard; the power of Industrial PCs; and the Windows operating system, enhanced by IntervalZero’s RTX64< hard real-time software that transforms Windows into a real-time operating system (RTOS), you can create software-only, PC-based machine controllers that lower the costs of industrial machines while delivering excellent precision and performance. There are two product lines: KINGSTAR Soft Motion and KINGSTAR EtherCAT.

KINGSTAR Soft Motion is a complete software solution that creates PC-based machine controllers with premium precision and performance.

KINGSTAR EtherCAT provides support for CANopen over EtherCAT and simplified configuration of EtherCAT networks.
