Project description
Overview US11269308B2 is a United States patent for creating and managing a network-connected smart PLC system. It lists Trisala Chandaria as the inventor and Ciambella Ltd. as the assignee, and it was granted on March 8, 2022. The patent connects an existing programmable logic controller (PLC) to a companion controller, a user interface, and a virtualization server. In plain terms, the PLC continues to control the sensors and actuators in the industrial system. The companion controller, called a CBD in the patent, connects the PLC to network services. The server generates applications…
