This series introduces only the technologies that I personally encountered at exhibitions and judged as truly useful for on-site improvement or distinctive in their approach.


Rather than simple product promotion, I focus exclusively on practical solutions that directly address real challenges in manufacturing environments.


========================================================

Practical Technologies Found at FOOMA JAPAN — Part 1

TSUBACO Kansai × PRO-SEED


FOOMA JAPAN 2026, held over four days at Tokyo Big Sight, attracted more than 110,000 visitors despite the approaching typhoon. Photography inside the venue was prohibited, which is unfortunate, because many practical solutions for food and manufacturing sites were exhibited.


Among them, the joint booth of TSUBACO Kansai Co., Ltd. (Tsubakimoto Group) and PRO-SEED Co., Ltd. showcased four technologies that directly contribute to on-site improvement.


With approval from President Kamimura of TSUBACO Kansai, I am sharing these insights here.


Below is the first installment.


① Siemens PLC Program Readout, Modification, and Data Extraction



Siemens PLCs (S7 series), commonly used in equipment imported from the EU, often become a “black box” in Japan:


  • Program cannot be read

  • Password unknown

  • No modification possible

  • No data extraction


These issues frequently occur at manufacturing sites.


The joint technology of TSUBACO Kansai × PRO-SEED enables:


  • Program readout

  • Program modification

  • Data extraction



This capability is extremely rare in Japan and highly valuable for factories in food, automotive, chemical, and other industries that rely heavily on imported equipment.

This article is written by me (Tanaka) based on technologies I discovered at the exhibition. If you are considering Siemens PLC program modification or retrofit work, please contact me first. I will introduce TSUBACO Kansai as needed.
