Abstract

A process control system (1) has a number of process controllers (3). A data controller (11) in a network (7) stores event data immediately it is generated by the process controllers. A monitor device (10) monitors this to determine failure of any process controller and there can be an immediate back-up by automatic retrieval of necessary parameter values from separate parameter input devices (15, 16). All processing of the process controllers (3) is caried out directly using a large high speed memory (9) for a very fast response.
