Siemens PLCs imported from Europe often become a “black box” in Japan, making program readout, password recovery, modification, and data extraction difficult. TSUBACO Kansai × PRO-SEED provides rare technical capability to unlock, modify, and extract data from Siemens S7 PLCs, offering practical solutions for factories relying on European equipment.

Manufacturers facing black box PLCs can still achieve safe, real-time data visualization by using dedicated PCs and mirrored client PCs as data hubs instead of accessing the PLC directly.
