Method for controlling field devices in industrial processes
A patent application (Publication Number: US20240036553A1) describes a method and system for facilitating messaging from a controller service to a field device in a process control environment. The method involves receiving messages from controller services, analyzing them, selecting an active message, detecting the address and command for a field device, and transmitting the command to manipulate the field device to drive the industrial process output. The system includes field devices, hosts executing I/O server services, and an orchestrator service for selecting active I/O server services. The I/O server services verify message freshness, perform load balancing, and evaluate quality-of-service metrics for each message to ensure efficient communication and control in the process plant.
Furthermore, the patent application details the configuration of servers implementing I/O server services to facilitate messaging in a process control environment. These servers receive messages from controller services, analyze them, select active messages, detect device addresses and commands, and transmit commands to manipulate field devices. The I/O server services ensure message freshness, execute in different containers for load balancing, and can be selected by an orchestrator service for optimal performance. Quality-of-service metrics are evaluated for each message to maintain effective communication and control within the industrial process. This innovative method and system aim to enhance efficiency, reliability, and responsiveness in process control environments by streamlining messaging processes between controller services and field devices.
