SEW DFP21B-U0H11B

SEW DFP21B-U0H11B

Product Introduction:
The DFP21B-U0H11B is a PROFIBUS DP-V1 fieldbus interface module manufactured by SEW-EURODRIVE, specifically designed for the MOVIDRIVE MDX61B series drive converters. It enables high-speed, reliable communication between SEW drives and PROFIBUS DP master systems, including PLCs from Siemens, Rockwell, and other major automation vendors. The “U0H11B” suffix denotes a specific hardware revision and production configuration of the DFP21B base module, which may reflect PCB revision, component batch, or firmware version.

Functional Features:

  • PROFIBUS DP-V1 Communication: Supports both cyclic data exchange (DP-V0) and acyclic parameter access (DP-V1) for comprehensive drive control
  • Remote Parameter Configuration: Enables reading and writing of drive parameters through the PROFIBUS network without physical access to the drive
  • Diagnostic Reporting: Transmits drive fault codes, operational status, and warning messages to the PROFIBUS master in real time
  • Multi-Drive Network Support: Multiple DFP21B-equipped drives can be connected on the same PROFIBUS segment, each with a unique station address
  • GSD File Integration: Standardized GSD file ensures compatibility with all PROFIBUS-compliant master systems
  • Compact Plug-In Design: Direct installation into the MDX61B expansion slot with no additional wiring required

Application Scenarios:

  • Packaging machinery with centralized PROFIBUS control
  • Printing and converting equipment
  • Electronic manufacturing assembly lines
  • Food and beverage processing systems
  • Logistics and conveyor systems
  • Any industrial application requiring PROFIBUS-based centralized drive monitoring and control

Performance Parameters:

  • PROFIBUS Baud Rate: Up to 12 Mbit/s
  • DP-V1 Acyclic Access: Supported for parameter read/write operations
  • Process Data: Configurable cyclic data mapping for speed, torque, status, and control commands
  • Station Address Range: Configurable via DIP switches or software
  • Response Time: Determined by PROFIBUS cycle time and number of slaves on the bus

Material Composition:

  • Industrial-grade PCB with surface mount components
  • DB9 or dedicated PROFIBUS connector
  • Metal shielding for EMC protection
  • Plastic housing with DIN rail mounting features

Structural Features:

  • Plug-in module form factor for MOVIDRIVE MDX61B expansion slot
  • PROFIBUS DP connector (9-pin D-Sub) for bus connection
  • DIP switches for station address configuration and bus termination
  • LED indicators for bus communication status, power, and error conditions
  • Internal power supply connection via the drive backplane (no external 24V wiring needed)

Working Principle:
The DFP21B module connects to the PROFIBUS DP network via its D-Sub connector and communicates with the MOVIDRIVE MDX61B drive through the internal backplane bus. During cyclic operation, the PROFIBUS master sends control words and setpoint values to the module, which forwards them to the drive for execution. The drive responds with status words and actual values (speed, current, position) that the module transmits back to the master. For acyclic operations (DP-V1), the master can read or write individual drive parameters on demand, enabling remote configuration and diagnostics without interrupting cyclic communication.

Installation Requirements:

  • Install the module into a compatible expansion slot on the MOVIDRIVE MDX61B drive
  • Connect the PROFIBUS cable to the D-Sub connector using proper pin assignment (Pin 3: B signal, Pin 8: A signal)
  • Configure the station address via DIP switches or MOVITOOLS software
  • Activate bus termination if the module is at the end of the PROFIBUS segment
  • Import the corresponding GSD file into the PLC engineering software for hardware configuration
  • Ensure the PROFIBUS cable is shielded and properly grounded per PROFIBUS installation guidelines

Usage Notes:

  • The “U0H11B” suffix indicates a specific hardware/firmware revision; when replacing a faulty module, the complete model string must match to ensure GSD file and parameter set compatibility
  • This module is exclusively compatible with MOVIDRIVE MDX61B series; it is not compatible with MC07B, MDX60B, or MOVIAXIS platforms
  • Verify the original module’s complete label string before ordering a replacement
  • Use the SEW official service portal or MOVITOOLS software to verify the exact technical documentation and firmware version for the specific part number
  • All original SEW communication modules carry a unique ordering number starting with “082” printed on the side label; modules without this marking should be treated as non-genuine
