Taschenbuch. Condition: Neu. Neuware - A SCADA is not there to show data. It is there to let an operator act on a site they cannot drive to - a booster station eleven kilometres away, a reservoir reachable only through another site, a tank running on solar and a battery. Every design decision in it is judged on one question: does it help the operator act, or does it drown the screen This book is written for the operator or technician who inherits a SCADA someone else configured and has to understand it, keep it alive, and defend its numbers to an inspector. - \*\*The four pieces\*\* - field, RTU, communication, central - and why the site must fail safe on its own when the central disappears.- \*\*Telemetry for real\*\* - the tag list everything rests on, the deadband that trades bandwidth against fidelity, and the delay every value already carries.- \*\*Alarms an operator can use\*\* - priority by action needed, flood suppression, and the chronically active alarm that hides the next real one.- \*\*Data that holds up\*\* - delivered-volume metering that survives an outage, a watchdog that does not lie about a lost link, a historian with no silent holes.- \*\*Remote command done safely\*\* - select-and-confirm, and the local limits a remote command must never override.>Every chapter ends by producing a completed field document - a tag list, an alarm rationale, a watchdog specification, a historian integrity test, a site commissioning plan. The blank forms are in Appendix D to photocopy. \*\*No brand names anywhere.\*\* The volume runs on one fictional plant - Ashford Bend Water Treatment Plant and its three remote sites - the same plant as Volumes 1 and 2. Neither is a prerequisite.…

Taschenbuch. Condition: Neu. Neuware - An instrumented plant does not have an on switch. It is brought from the end of construction to production through a sequence of gates, each proved before the next may open - and it is not finished when the instruments read and the loops hold, but when you can PROVE they do, and the proof is traceable. Building that proof is a trade, and nobody teaches it as one. You learn it by getting it wrong in the field. This book turns it into a method. It is written for the technician or engineer who inherits a built plant and has to hand it over. - \*\*The nine commissioning gates\*\* - from the installation walkdown to the handover certificate, each with an acceptance criterion and the document that proves it.- \*\*The punch list that closes\*\* - three defect classes, what blocks energization, what blocks handover, and what crosses into warranty declared instead of smuggled.- \*\*Cold loop check versus hot\*\* - what continuity proves, what only a responding process can, and the loop that passes cold and fails hot.- \*\*Proving the remote sites\*\* - point-to-point across a radio path, and the drop-out test done the only way that counts: by removing the radio.- \*\*The functional test\*\* - every interlock fired for real, and the line between a process interlock and a safety function, which is validated elsewhere.>Throughout, one loop - the chlorine cascade - is followed through all nine gates. Every chapter ends by producing a completed field document; the blank forms are in Appendix D to photocopy. This is the fourth and final volume of the series: the measurement made true, the control made to hold, the far network carried home, and the proof that ties them into one plant. \*\*No brand names anywhere.\*\* The volume runs on one fictional plant - Ashford Bend Water Treatment Plant - the same plant as the whole series. The others are not prerequisites.…

Taschenbuch. Condition: Neu. Neuware - PID tuning is the last home of folklore in the plant - rules handed down, numbers copied from one loop to the next, and a widespread belief that it is an art. It is not. It is a procedure that starts from a measurement of how the process actually responds, and the reason almost nobody does it is that almost no book explains how to make that measurement. This one starts there. It is written for the technician who has to make a plant hold a value and then defend the result - and it teaches the honest truth most books avoid: a loop that will not hold almost always has its problem OUTSIDE the controller, in the measurement, the valve, or the process dynamics. Changing the gains only hides it. - \*\*The step test\*\* - how to measure process gain, dead time and time constant off a trend with a ruler. No Laplace transform appears anywhere in the book.- \*\*Tuning as a procedure\*\* - with a defined stopping point, and the dead-time-to-time-constant ratio that tells you honestly when tuning cannot help at all.- \*\*Valves for real\*\* - characteristic, authority, the installed characteristic, and why an oversized valve controls only in the first fifth of its travel.- \*\*The structures a single loop cannot replace\*\* - cascade on the dead-time-bound chlorine loop, ratio on the coagulant dose, feedforward, override, split range, and the two loops that fight each other until you deliberately slow one down.>Every chapter ends by producing a completed field document - a step test record, a tuning record, a valve sizing sheet, an oscillating-loop diagnosis, a commissioning report - filled in with real numbers and reproducible with a pen. The blank forms are collected in Appendix D to photocopy. \*\*No brand names anywhere.\*\* The volume runs on one fictional plant - Ashford Bend Water Treatment Plant - the same plant as Volume 1. Volume 1 is not a prerequisite, but this book assumes the measurement is already trustworthy; making it trustworthy is Volume 1's subject.…

Throughout, one loop - the chlorine cascade - is followed through all nine gates. Every chapter ends by producing a completed field document; the blank forms are in Appendix D to photocopy.
