PROFIBUS Interface

Interface to a PROFIBUS communication bus
  • Connects dSPACE Simulator and prototyping systems to the PROFIBUS Network
  • Dual-port memory for data exchange with processor board
  • Master or slave PROFIBUS modules available
  • Communication without load on the host system

Application Areas
Processing closed-loop and open-loop control information for machinery and systems with the aid of powerful microchips is widespread in modern automation technology. As a rule, the processors are connected by one or more communications networks. The PROFIBUS interface connects dSPACE Simulator and dSPACE prototyping systems to PROFIBUS networks to develop controller technologies for factory automation, decentralized peripherals, and motion control, for example.

Key Benefits
The PROFIBUS Interface is equipped with the PHS++ bus interface and can therefore communicate with the dSPACE modulare hardware at very high speeds. The maximum possible baud rate for PROFIBUS communication is 12 Mbaud. A sample setup with a ControlDesk experiment comes with the interface to explain the basic implementation of dSPACE modulare hardware in PROFIBUS environments.

The PROcess-FIeld-BUS is a vendor-independent, open field bus standard for a wide range of applications in manufacturing and process automation. Vendor independence and openness are ensured by international standards IEC 61158 and IEC 61784. PROFIBUS allows communication between devices from different manufacturers without any special interface adjustment. PROFIBUS can be used for both high-speed, time-critical applications and complex communication tasks. It utilizes a nonpowered two-wire (RS485) network and can have up to 126 nodes.
