BARANDICA LOPEZ, Asfur  e  GUEVARA ESCOBAR, Andrés Ernesto. Gateway to use HART transmitters from a DeviceNet network. ing. [online]. 2015, vol.20, n.1, pp.101-105. ISSN 0121-750X.

This paper demonstrates the feasibility of harmonizing two industrial protocols with very different characteristics, through the implementation of a hardware-software interface. HART is a very low speed protocol that operates with master-slave paradigm, connectionless oriented and with a defined set of commands, while DeviceNet is at least 100 times faster, works with the producer-consumer model, is connection-oriented and does not use commands but objects. The development is supported on the TINI (Tiny InterNet Interface) embedded system, which is Java programmable. The gateway acts as a slave on a DeviceNet network and as master of a HART network. This innovative equipment can be used to include HART devices in manufacture processes requiring few continuous variables.

Palavras-chave : DeviceNet; gateway; HART protocol; industrial communications; industrial networks.
