An infrastructure of modern production systems is based on technologically advanced machines and devices. One of the important issues in this aspect is to ensure the smooth communication among elements of the industrial automation infrastructure to ensure the quality, stability and safety of a production system as well as the right identification of resources using in production processes. The article presents a model of communication between measuring points in a production system with the use of a selective RFID gate as a result of R&D project made by DataConsult Sp. o.o. The model can be scaled and applied in different manufacturing companies. It is based on the assumption of parallel and independent communication on a configuration of industrial automation components that enable to use advanced and safety solutions of data collection, processing and sharing.

Celem artykułu jest prezentacja wyników prac rozwojowych dotyczących systemu DataConnect z zastosowaniem mechanizmu komunikacji Universal Data Exchange Interface dla modelu wymiany informacji pomiędzy systemem ExpertWMS®, a systemami zewnętrznymi ERP. Prace rozwojowe były ostatnim etapem badań nad stworzeniem odpornego na zaburzenia elektromagnetyczne prototypu systemu punktów pomiarowych przy gniazdach produkcyjnych opartego o technologię selektywnej bramki RFID. W artykule zaprezentowano zarówno teoretyczne jak i praktyczne podejście do problematyki wymiany danych i komunikacji w przedsiębiorstwach przemysłowych, które w zarządzaniu wykorzystują złożone systemy informatyczne wspomagające procesy produkcyjne, logistyczne i biznesowe.

Abstract. The aim of paper is to present results of the research work in development conducted to define the scalability conditions for the measuring points network at production cells in the resistant to the electromagnetic disturbances system based on the patented selective RFID gate technology. This is a conceptual paper that includes research results of the selective RFID gate and its place in a production system, a communication model between two measuring points in a complex production system that was the input to do further analysis required to define its scalability conditions. The proposed approach provides the following results: order and speed of data reading from measurement points, data transfer between measurement points, access to database, communication between the database and measurement points, data archiving, procedures of changing the measurement point configuration in the system, including error handling and network re-configuration. It is believed that both practitioners and researchers will benefit from it.
