A picture may be worth a 1000 words, but a picture plus its story can be worth 5000 words! Learn the importance of control narratives (a.k.a., control descriptions, loop descriptions) and how they augment P&IDs to give a reader the complete picture, beyond just a cropped image.
Explain why many P&IDs cannot be used only at face value.
After participating in this session, participants will be able to recognize related items in a control loop.
Distinguish between switches and signals and assess whether they're accessible via the field, via a remote station control room, and/or via a centralized Operations center.
