The EK9300 PROFINET IO bus couplers available from BECKHOFF Automation can connect different control networks with each other in a simple and efficient manner.


This enables a PROFINET controller to exchange data with one or more EtherCAT, PROFINET, PROFIBUS and EtherNet/IP systems. Thus, the EK9300 can be used as a flexible gateway for real-time communication between these networks, with all the advantages provided by the EtherCAT network as an extremely high performance lower-level I/O system.


The EK9300 bus coupler converts the telegrams from PROFINET IO to the EtherCAT E-Bus signal type. One station consists of an EK9300 and any number of EtherCAT terminals. The coupler supports the PROFINET RT protocol and, therefore, fits seamlessly into PROFINET IO networks.


With its new firmware and the corresponding EtherCAT terminals, the EK9300 bus coupler can be used as a flexible gateway between different network and controller types: from PROFINET to EtherCAT (with EL6692-0000); from PROFINET to PROFINET (with EL6631-0010); from PROFINET to PROFIBUS (with EL6731-0010); and from PROFINET to EtherNet/IP (with EL6652-0010). 


Heterogeneous production systems can therefore, be networked by real-time communication without great effort and expense. For example, product-relevant management information can be collected in distributed units with different control systems or data can be exchanged in real-time between two PROFINET networks deliberately placed in different IP spaces.


EtherCAT: High-performance sub-bus with a wide I/O product range


The EK9300 PROFINET IO coupler offers underlying connectivity to the high-performance and ultra-fast EtherCAT I/O system. Additional advantages are gained particularly for widely distributed systems because the EtherCAT network topology offers high flexibility and the ability to bridge long transmission distances of up to 100m. 


Another key benefit is that the EK9300 bus coupler, in addition to its actual gateway function also supports the extremely wide I/O range of EtherCAT terminals including numerous IP 67 box modules for installation in harsh environments. This allows the optimum mapping of the physical process on the one hand and on the other, allows the connection of a PROFINET controller via several EtherCAT slave terminals to the corresponding number of identical or different control networks.
