Unitronics Manuals & User Guides

ユニトロニクス is a global leader in the development and manufacture of industrial automation products, best known for its pioneering "All-in-One" solution that integrates a Programmable Logic Controller (PLC) with a Human-Machine Interface (HMI) panel. Founded in 1989, the company provides a comprehensive range of control devices that streamline automation tasks by eliminating the need for separate PLC and HMI components, thereby reducing wiring, programming time, and cabinet space.

The company’s product portfolio includes the powerful ユニストリーム series for complex machinery, the ビジョン series for advanced control, and the サンバ series for smaller applications. In addition to hardware, Unitronics offers a unified programming environment—such as VisiLogic and UniLogic—allowing engineers to configure hardware, communications, and HMI designs in a single software platform. Their solutions serve diverse industries including petrochemicals, automotive, food processing, plastics, and energy, backed by a global support network.

• Where can I download the programming software for Unitronics PLCs?

  Software such as UniLogic, VisiLogic, and U90 Ladder can be downloaded free of charge from the Technical Library section of the official Unitronics webサイト。
