netLINK PROXY integrates any PROFIBUS DP slave into a superordinate PROFINET network. Designed as a connector, the device is plugged directly onto the PROFIBUS DP interface of the DP Slave and connected to the PROFINET network via the RJ45 socket.

On the PROFINET side netLINK behaves like an ordinary IO Device. The process data of the DP Slave are mapped into the PROFINET slot/subslot addressing model in accordance with the guidelines of PROFIBUS and PROFINET International (PI).

Commissioning is performed via the Ethernet port by a direct connection to the PC or during run time via a PROFINET switch, if already installed. netLINK PROXY is configured with the FDT/DTM based planning, configuration and diagnostic tool SYCON.net.

It only takes a few steps to make netLINK ready for operation. If the GSD-file of the slave is not available directly, a scan function allows its automatic identification on the PROFIBUS. Once the slave’s configuration and I/O process data length are identified, SYCON.net automatically converts the parameters into a standardized GSDML file. Importing this file into any PROFINET controller configuration utility and putting the netLINK into operation is fairly simple.

The netLINK Proxy has a 24 V supply. During mounting the voltage can be tapped comfortably from the DP-Slave and applied to the 2-pin COMBICON connector. The short distance on PROFIBUS renders a bus terminal resistor unnecessary.

netLINK PROXY – a cost-efficient and handy alternative to redevelopments for the convenient and easy integration of existing DP devices into the PROFINET world.

Gateways are for transferring and converting data between two identical or two different industrial automation networks. They provide a cost-effective solution that is easy to deploy for any kind of data conversion whether the application is a classic fieldbus, Ethernet, Real-Time Ethernet or a combination.
