Примена OPC сервера у аквизицији стања технолошких система

Abstract

Dinamičko okruženje zahteva od tehnologa neprestano usavršavanje i optimizaciju postojećih, kao i uvođenje novih tehnoloških procesa. Implementacijom programabilne automatizacije, a naročito njenom integracijom u sveobuhvatni upravljački sistem, znatno je olakšano ostvarivanje pomenutih zahteva. Međutim, njena primena u navedenim uslovima često zahteva neprestano prisustvo obučenog osoblja u tehnološkom okruženju. Stoga, uvođenjem standarda "Open connectivity" (OPC), omogućava se neometan i transparentan pristup stanjima unutar tehnološkog sistema, te i lakše ostvarivanje pomenutih zahteva, kroz didrektan pristup memorijskim lokacijama, a time se otvara i mogućnost uticaja na tok izvršenja upravljačkog programa, te tako i na sam tehnološki proces.

A dynamic environment requires technologists to constantly improve and optimize existing, as well as introduce new manufacturing processes. The implementation of programmable automation, and especially its integration into the comprehensive control system, greatly facilitated the realization of the mentioned requirements. However, its application in the mentioned conditions often requires the constant presence of trained personnel in the manufacturing environment. Therefore, by introducing the "Open connectivity" (OPC) standard, unhindered and transparent access to the states within the manufacturing system is enabled, as well as easier realization of the mentioned requirements, through didactic access to memory locations, and thus opens up the possibility of influencing the course of execution of the control programme, and as well as the manufacturing process itself.
