Industrial communication networks - Wireless communication networks - Part 2: Coexistence management

IEC 62657-2:2013 specifies the fundamental assumptions, concepts, parameters, and procedure for wireless communication coexistence; provides guidelines, requirements, and best practices for wireless communication's availability and performance in an industrial automation plant; it covers the life cycle of wireless communication coexistence and provides a common point of reference for wireless communication coexistence for industrial automation sites as a homogeneous guideline to help the users assess and gauge their plant efforts. This first edition cancels and replaces IEC/TS 62657-2, published in 2011. The main changes with respect to the TS are: - updated the normative references, terms, definitions, symbols, abbreviations; - corrected spelling; - changed figures to make them consistent with the text and vice versa; - added and modified text to make the text more readable.

Industrijska komunikacijska omrežja - Brezžično komunikacijsko omrežje - 2. del: Upravljanje soobstoja (IEC 62657-2:2013, spremenjen)

Standard IEC/TS 62657-2:2011(E) določa temeljne predpostavke, koncepte, parametre in postopek za upravljanje soobstoja brezžičnih komunikacij. Zagotavlja smernice, zahteve in najboljše prakse za razpoložljivost in delovanje brezžične komunikacije, pri čemer zajema življenjski cikel soobstoja brezžične komunikacije za pomoč pri delu vsem vključenim osebam z ustreznimi odgovornostmi za obvladovanje kritičnih vidikov v vsaki fazi upravljanja soobstoja brezžične komunikacijske v avtomatiziranem obratu. Poleg tega zagotavlja skupno referenčno točko za soobstoj brezžične komunikacije za industrijske avtomatizirane obrate kot homogeno smernico za pomoč uporabnikom pri oceni in izmeri rezultatov obrata. Vidiki življenjskega cikla, vključujejo: načrtovanje, projektiranje, montažo, izvedbo, obratovanje, vzdrževanje, upravljanje in usposabljanje.
