1. A control system performance tracking apparatus comprising:
a data memory device coupled in use to a plurality of control devices of a control system, the data memory device being configured to:
monitor the plurality of control devices;
receiving data related to inputs, outputs and events of each control device;
time stamp said data on a common time base; and
store a resulting time-based sequence data for each of the plurality of control devices; and
a processor configured to compile the sequence data for the plurality of control devices into a common data stack
wherein the apparatus is further configured to:
accumulate historical data to form at least one reference sequence data model; and
compare a measured sequence data to the reference sequence data model to identify operational deviations,
wherein the data memory device compiles at least the following groups of device data:
Digital Input/Output data, Analogue Input/Output data and event logs and the reference sequence data model comprises Digital Input/Output data to provide reference sequence data models for sub-processes.
