PROFIBUS DP Master for Altera FPGA

Integration of PROFIBUS DP into Industrial Controllers using Intel (Altera) FPGA

The PROFIBUS DP Master IP Core integrates components required for implementing a complete PROFIBUS DP Class1 and Class2 Master based on FPGA technology. Thus, no specific fieldbus controller ASIC is needed in addition.

PROFIBUS DP Master for Altera FPGA

Minimum Development Effort

  • Combination of all components required for implementing a PROFIBUS DP Class 1 or Class 2 Master into a Field Programmable Gate Array (FPGA)
  • PROFIBUS DP bus control logic available as loadable IP Core
  • PROFIBUS DP protocol stack ready to be used on soft core processor within FPGA
  • Control application running on second processor inside the FPGA or on separate external host processor
  • Including PROFIBUS DP versions DP (exchange of cyclic data and diagnosis with slaves), DP-V1 (acyclic data exchange and alarm handling) as well as DP-V2 (clock synchronization and time-stamping)

Flexibility Through Integrated Fieldbus Controller

  • Provision of complete bus control logic for accessing PROFIBUS DP network
  • Handling of all time-critical parts of PROFIBUS DP Data Link Layer, token handling and cyclic data exchange
  • No dependency on fieldbus controller ASIC and its vendor

Improved Plant Availability

  • Support of Master redundancy providing seamless switchover from primary to backup PROFIBUS DP Master
  • Optional line redundancy functionality for accessing field devices via redundant fieldbus cables
  • Support of re-configuring individual PROFIBUS slaves without shutting-down plan

PROFIBUS DP-V1 Features
  • Alarms
  • Extended Diagnostics
  • Acyclic Read/Write (Class 1 and Class2)
  • Data Transfer (Load Region)
Additional Features
  • Online Change (Re-configuration of individual slaves while the rest of the plant continues operating)
  • Diagnostic History (Diagnostic messages are stored in a FIFO of configurable size until they are read by the application)
  • Optional Synchronization Between PROFIBUS DP Poll Cycle and Application
  • Preprocessing of Input Data (The application is notified when data have changed)
Optional Features (Part of Version)
  • Master Redundancy (Seamless Master Switchover, Requires Redundancy Link Between Active Master and Backup Master)
  • PROFIBUS DP-V2 Features (Clock Synchronization, Time Stamps)
Optional Feature (Separate Item)Line Redundancy (Operates Two Independent Physical Connections)

Fast Implementation of Custom Industrial Ethernet Connectivity Solutions

In addition to the IP cores for FPGA integration, Softing Industrial Automation also offers the development and production of FPGA-based communication interfaces. This offer is based on a pre-engineered reference design that reduces the time to market to a minimum. The Softing reference design includes the required hardware and software for field device implementation and is the result of decades of experience in industrial communication. The solution features a Field Programmable Gate Array (FPGA) core combining a future-proof design with a flexible implementation that can be optimally adapted to meet individual customer requirements. It has already been prepared to support common Industrial Ethernet protocols – EtherCAT, Ethernet POWERLINK, EtherNet/IP, Modbus TCP and PROFINET.

Proven in a Wide Range of Applications

Many leading automation providers trust and rely on Softing's expertise. The Softing reference design thus is already in use in numerous customer implementations and in Softing's own products. It proves its capabilities, functionality and performance every day in a vast range of applications in many vertical markets and all around the world.

Efficient Universal Application Interface

Uniform, simple-to-use interfaces are available to ensure easy connectivity of the application. The Simple Device Application Interface (SDAI) for device integration and the Simple Controller Application Interface (SCAI) for controller integration are designed to offer efficient access to the protocol functions and support many different hardware architectures. The protocol-independent implementation eliminates the need to modify the application when changing to another Industrial Ethernet protocol.

Implementation of Any IT Services

Softing's reference design allows to integrate standard IT services into the field device by using the same cable and the same Ethernet interface. This transparent IT channel enables versatile use, for example, to implement a web server, download data, use email services or implement custom services within a field device.
