Internet based wireless data communication in industrial automation

The network requirements of the control systems in the industrial applications increase day by day. The internet based control system and various fieldbus systems have been designed in order to resolve these requirements. While the designs of the communication systems are prepared, it should be kept in mind that the system will expand in future. In this paper, internet based control system that will be able to meet the system requirements with a novel communication structure is called wired/wireless hybrid system has been designed on field level and carried out. The system has been accomplished with a programmable logic controller (PLC), a communication processor (CP) module, two industrial wireless (IWLAN) modules, and a distributed I/O module and Motor Protection Package. Commissioning and testing of all distributed I/O has been implemented via wired/wireless communication. The aim of the designed system is to provide convenient and cheaper solution in harsh environment by using higher speed data transfer feature of the Profinet network structure, and also to offer a new opportunity to realize cost-effective, flexible, scalable and reliable systems for distributed architectures.
