KINGSTAR Soft Motion provides all the benefits of a software solution to motion control in an automatically configured EtherCAT environment with “plug-and-play” compatibility. With the highest quality and performance of pre-integrated and pre-tested motion libraries, KINGSTAR delivers motion control at half the cost of traditional hardware platforms. Deliver Software-Only Motion Control and Positioning Systems Quickly and Affordably KINGSTAR Soft Motion is an open and standards-based, software-only solution that streamlines motor control and automation. Soft Motion runs directly on the PC, uses the NIC card for I/O, and uses the powerful EtherCAT protocol to free you from the shackles of proprietary and costly hardware. With Soft Motion, motion control engineers can design, develop and integrate PC-based machine controllers in a “plug-and-play” environment for consolidated, inexpensive and scalable motion and vision control.

Product Release Notice: KINGSTAR 3.2

POSTED 04/09/2018

 | By: Terri Hawker, Vice President Product Management

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.
