Product Description

Lifecycle Status:
PROFINET is the open Industrial Ethernet standard of the PNO (PROFIBUS Nutzerorganisation). Internationally established IT standards are used for communication. PROFINET RT describes the data exchange between controllers and field devices and can be used in standard Ethernet networks. Commercial switches are used for networking purposes. Linking to any PROFINET controller takes place via the GSDML basic device file. The BK9053 Bus Coupler connects PROFINET with the modular, extendable electronic terminal blocks. One unit consists of one Bus Coupler, any number from 1 to 64 terminals (255 with K-bus extension) and one end terminal. The Bus Couplers recognize the terminals to which they are connected, and perform the assignment of the inputs and outputs to the words of the process image automatically.
