I/O server services for selecting and utilizing active controller outputs from containerized controller services in a process control environment

An I/O server service interacts with multiple containerized controller services each implementing the same control routine to control the same portion of the same plant. The I/O server service may provide the same controller inputs to each of the containerized controller services (e.g., representing measurements obtained by field devices and transmitted by the field devices to the I/O server service). Each containerized controller service executes the same control routine to generate a set of controller outputs. The I/O server service receives each set of controller outputs and forwards an active set to the appropriate field devices. The I/O server service and other services, such as an orchestrator service, may continuously evaluate performance and resource utilization in the control system, and may dynamically activate and deactivate controller services as appropriate.

Claims preview

1 . A method of facilitating messaging from a controller service to a field device in a process control environment, the method comprising: receiving, at one or more input/output (I/O) servers, a plurality of messages from a plurality of controller services, each implemented in a respective container and each executing a same control routine to generate a message including a set of commands to control a same portion of an industrial process via the same one or more field devices; performing, at the one or more I/O server services, an analysis of the plurality of messages; selecting, by the one or more I/O server services and based on the analysis, an active message from the plurality of messages; detecting from the active message (i) an address for a field device and (ii) a command to manipulate the field device; and responding to detecting the command and the address for the field device by transmitting, at the one or more I/O server services, the command to the address for the field device to manipulate the field device in a manner that drives a process output of the industrial process. 2 . The method of claim 1 , further comprising verifying that the active message has been refreshed by the corresponding controller service within a given time period sufficient to confirm that the active message is not stale before transmitting the active message to the field device. 3 . The method of claim 1 , wherein the one or more I/O server services is a plurality of I/O server services each executed in a different container, wherein the plurality of I/O server services includes (i) a first I/O server service that has been designated as an active I/O server service and (ii) one or more other I/O server services, wherein receiving the plurality of messages from the plurality of controller services includes receiving the plurality of messages at each of the plurality of I/O server services.
