DISTRIBUTED COMPUTING IN A PROCESS CONTROL ENVIRONMENT

摘要

High availability and data migration in a distributed process control computing environment. Allocation algorithms distribute data and applications among available compute nodes, such as controllers in a process control system. In the process control system, an input/output device, such as a fieldbus module, can be used by any controller. Databases store critical execution information for immediate takeover by a backup compute element. The compute nodes are configured to execute algorithms for mitigating dead time in the distributed computing environment.

1. A system for providing process control, comprising:
a communication channel; a plurality of compute nodes each connected to the communication channel; one or more executive nodes providing a set of executive services connected to the communication channel, wherein the compute nodes and the set of executive services comprise a distributed computing environment; and an input/output (I/O) application providing an electronic datapath between a process control device and the communication channel, wherein at least one of the compute nodes includes the I/O application.
