Airion Inc. (Head Office: Tokyo; Representative Directors: Takumi Kawamura and Takumi Ohkuma) is pleased to announce that it has joined "PLCopen Japan," an organization that promotes the international standardization of industrial controllers, as a vendor member.

  1. Announcement of Vendor Membership

We have joined PLCopen Japan, a general incorporated association that promotes the adoption of international standards for industrial controllers, as a vendor member. Through this membership, we will support the development of engineering environments based on globally standardized technical specifications and contribute to making manufacturing sites even more intelligent and efficient. 2. Reasons and Objectives for Joining: Innovating Control Engineering with AI

We develop and provide "Ladder-kun," an AI programmer that uses generative AI to automate PLC programming.

On today's manufacturing floors, programs are rapidly becoming larger and more complex as equipment grows more sophisticated—a trend toward "software-rich" systems—and rising engineering costs have become a major challenge. Through this membership, we will directly incorporate expertise in program structuring and componentization compliant with the international standard "IEC 61131-3" into the development of "Ladder-kun," pushing the reliability and versatility of the generated programs to the highest possible level. 3. ** About PLCopen**

PLCopen Japan is an organization that began its activities at the end of 2002 with the aim of promoting "IEC 61131-3," the international standard for industrial controller programming languages. Today, the standard (in its JIS edition) is widely adopted around the world, and in Japan as well, advanced control using "Function Blocks (FB)" and "Structured Text (ST)" has become mainstream in the field of machine control. By promoting the structuring, componentization, and reuse of programs, the organization helps reduce ballooning engineering costs and contributes to the advancement of manufacturing sites by fostering open, vendor-independent engineering environments.

Airion is a technology company committed to "Manufacturing × AI," driving the social implementation of "Physical AI," which fuses cutting-edge AI technology with robotics.

Our solutions connect AI from "inside the screen" to "action in the physical world," including "Ladder-kun," which streamlines PLC programming with our proprietary LLM, control of single-arm robots using VLA (Vision-Language-Action) models, and live demonstrations using a robot dog. With a flexible, manufacturer-agnostic development structure, we help reduce on-site workload and support skills transfer.
