During my 15 years in the control system business I have seen total lock out of a multiple operator stations on a plant DCS once and heard about perhaps three times. I am wondering if the use "third party" PCs and industry standard ethernet is increasing this unacceptable event. Please let me know if you have had any issues with total loss of process view using any of the modern DCSs, i.e., DeltaV, PlantSCAPE, ControlIT etc.
