Integration of remote interfaces for industrial automation applications

Abstract

This paper presents a remote interface solution for industrial automation applications based on the integration of automation Fieldbuses with different technologies. This solution is obtained by the connection of an Industrial Ethernet Fieldbus with a classic Fieldbus, through a strategy of software and hardware compatibilization. The compatibility of the software is achieved through the AXC 1050 PROFINET controller, communicating using the PROFINET and Modbus TCP/IP protocols and the programming of the Modbus RTU protocol, in the Siemens S7-215-2 PLC, in freeport mode, creating a bridge between both devices and their inputs/outputs variables. The development of this solution allows access to all existing equipment through a commercial Ethernet Fieldbus and the control of the S7-215-2 from other equipment of the Fieldbus, assigning new features to this controller that originally did not have this capability.
