KINGSTAR 3.6.1 is Now Live: What You Need to Know

by | Aug 16, 2019

We’re pleased to announce that our latest release, KINGSTAR 3.6.1, is now available. KINGSTAR 3.6.1 includes powerful new features for Windows-based Realtime Soft Motion and EtherCAT, as well as updates, bug fixes, and support for new hardware.

We’re most excited about the new features in KINGSTAR Soft Motion and that this release sets the foundation for Machine Automation that can support world-wide Industry 4.0 initiatives.  For example, KINGSTAR offers native language support such as Chinese.  In addition, KINGSTAR PLC now supports Symbolic constants, in the size of Array/Matrix variables and has an improved sample program.  We have also added COM Port over EtherCAT support and a diagnosis interface window to the KINGSTAR Analysis Console.

KINGSTAR 3.6.1 also resolves several known issues.

Read the full product release notes below for all the details, and as always, get in touch with any questions.

General Availability Release Date: August 19, 2019

Product Overview

KINGSTAR is an all-software, complete “plug-and-play” PC-based Machine Automation platform for IoT and Industry 4.0.  Key pre-tested and pre-integrated industrial machine components include software-based motion control, machine vision, programmable logic controller (PLC) and the industry’s only plug-and-play EtherCAT master that auto-discovers any vendor’s EtherCAT drive, IO or device and auto-configures the EtherCAT environment at startup.  Built on the EtherCAT standard and supported by a real-time 64-bit Windows operating-system (RTOS) from IntervalZero, KINGSTAR empowers engineers to design, develop and integrate machine control applications or a system of controllers on a single Industrial PC. The KINGSTAR platform can replace all hardware with software-only motion controllers and machine vision positioning systems, quickly and cost effectively

There are two product lines: KINGSTAR Soft Motion and KINGSTAR Fieldbus powered by EtherCAT.

KINGSTAR Motion replaces hardware motion cards with an all-software solution that creates PC-based machine controllers for premium precision and performance.
KINGSTAR Fieldbus powered by EtherCAT offers support for CANopen over EtherCAT and simplifies configuration of EtherCAT networks with its unique plug-and-play approach.
