Launch of NX502, New Controllers with Advanced Information Control and Safety Control

Contributing to Achieving High Production Quality and Improving Energy Productivity

OMRON Corporation (Headquarters: Shimogyo-ku, Kyoto; President and CEO: Junta Tsujinaga) will release the NX-series NX502-1□00 CPU Units (hereinafter referred to as “NX502″), automation controllers with advanced information control and safety control, and the NX-EIP201 EtherNet/IPTM Units (hereinafter referred to as “NX-EIP201”), simultaneously globally on April 24, 2023.

With the growing importance of ESG management, efforts to achieve carbon neutrality are becoming more active at manufacturing sites. In addition, manufacturing sites involved in products that are undergoing remarkable technological innovation, such as xEVs and digital devices, are facing the challenge of building lines that can respond to rapid yield improvement and flexible equipment design in order to respond to sudden fluctuations in demand.

The NX502 CPU Units and NX-EIP201 EtherNet/IP Units utilize OMRON’s unique advanced information processing, communications technologies and large capacity memory to realize real time analysis and process modularization*1. This contributes to the reduction of resource disposal losses at production sites and the shortening of lead times when changing lines.

Main Features

(1) World’s highest precision*2 data collection and large-capacity transfer capabilities reduce resource disposal losses at production sites

With high-precision data collection capability with a jitter of 1 μs or less and data transfer capacity approximately four times that of equivalent class controllers*3, production-related data (temperature, pressure, flow rate, etc.) can be analyzed and reflected in processing conditions in real time. It realizes rapid improvement of processes that cause defective products and reduces resource disposal losses at various production sites.


【Application example】 Crystal manufacturing process required for precise product processing

In order to produce high quality crystals, production-related data must fluctuate in real time depending on conditions, and there is a problem that manufacturing quality is not stable due to the limitations of communications performance, which is a bottleneck. The high information processing capability of the NX502 enables early identification of the cause, which leads to improvements in production conditions and contributes to stable mass production of crystals.

(2) NX-series first integrated control technology*4 for large-scale and high-speed safety reduces lead times when changing production lines

The integrated control technology advanced by the NX502 and NX-EIP201 allows you to control large-scale production lines with module division through up to 8 network system separations and up to 254 safety connections*5. This makes it possible to adjust and check partial processes with minimal impact on overall operations even on large lines and maximizes energy productivity by significantly reducing lead times when changing lines.


【Application example】 Body frame welding line handling a wide variety of products

According to the diversification of market needs, when it is necessary to add or change processes while mixed production of various vehicle models is required, it is necessary to minimize lead time by stopping only the relevant parts. The NX502 and NX-EIP201 can separate network systems, including safety. We can flexibly respond to detailed changes in manufacturing sites, such as the addition of welding processes, and contribute to improving production efficiency.

OMRON has been contributing to the improvement of productivity at manufacturing sites by leveraging its strength in control technology under the Innovation Concept innovative-Automation. We aim to achieve sustainable manufacturing sites such as carbon neutrality in production in addition to improving productivity at manufacturing sites from now. OMRON will enrich the future for people, industries and the globe by innovative automation.
