A system in which the Single-window Monitor sends wireless call bell signals to PLC equipment via RS485 for control
At Company C's large logistics center, robots sort goods automatically.
Wireless call bells were needed to summon the logistics robots controlled by the PLC control panel, and self-powered call bells were chosen for easy installation and maintenance.

In phase 1, the loading-station robot control system was pilot-tested and verified; in phase 2, it was expanded to all sections of the logistics center, and wireless robot calls across all sections were confirmed using relays. A call bell is mounted at each chute on site, and pressing it brings a robot.
Relays secure wireless range, making it easy to add units anywhere
Lower installation and maintenance costs with no cabling or battery replacement
Expansion under way to additional Company C logistics centers and other logistics automation companies
