METHOD AND SYSTEM FOR TESTING A CONTROL SYSTEM FOR A MARINE PETROLEUM PROCESS PLANT

摘要

A system for testing whether a control system (2) is capable of detection and handling of faults, failures or failure modes (8) in a petroleum process plant (1), said system (2) arranged for being * connected with input signal lines (30) for receiving sensor and other input signals (30) from said plant (1), * connected with control signals lines (40) for transmitting control signals (4) to said plant (1), comprising the following features * said control system (2) arranged for receiving simulated sensor signals or other input signals (3s) from a simulated petroleum process plant (10) over said line (30), * said control system (2) arranged for transmitting control signals (4) to said simulator (10) over said line (40), the invention comprises the features: * an input signal modifier (9) arranged for being connected to said line (30), *said modifier (9) arranged for modifying one or more said input signals (3) into modified input signals (13), * said modifier (9) being arranged for transmitting one or more of said signals (13) and remaining non-modified input signals (3) to said system (2).
