Fecha de publicación: 15/12/2022 Fuente: WIPO "hive" A method of process control in a PCS. The PCS provides host controllers coupled together, I/O devices, field devices, and processing equipment, configured together to run a process, the plurality of host controllers having stored a single online orchestrator program for coordinating a shared and synchronized database for the host controllers, wherein the online orchestrator program uses and tracks currently available host controllers and selected control programs for controlling the process. The PCS also includes an offline orchestrator. The orchestrator is run on the currently available host controllers that shares and synchronizes the initial shared database version to the currently available host controllers. A selected host controller responsive to an event broadcasts updated shared database version to the currently available host controllers. The offline orchestrator accepts commands relating to a deployment/undeployment of control program(s) among the currently running host controllers in response to changing requirement(s) by the control programs or an outside environment.
