The January 2019 S4 presentation on cyber security of Level 0,1 devices and actual case histories is on Dale Peterson’s Youtube channel - https://www.youtube.com/watch?v=c2gK8Zp6dv8&feature=youtu.be The Control System Basics slide is the entire end-to-end control system loop. Most people understand the OT and OT aspects of the slide but not the Level 0,1 devices. Yet, it is the Level 0,1 devices that directly affect process safety, reliability, and productivity, and product quality.
