ISBN: 9798193821182 - water and wastewater scada in practice: a hands-on guide to telemetry, rtus, alarm management, historians and compliance reporting for water and wastewater operators (5 risultati)

Taschenbuch. Condizione: 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.…

Paperback. Condizione: new. Paperback. A SCADA is not there to show data.

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.- **The compliance chain** - one chlorine number traced from the farthest sensor on the network all the way to the monthly report the regulator reads. 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.
