SEW DFP21B PROFIBUS DP-V1 Fieldbus Interface

SEW DFP21B PROFIBUS DP-V1 Fieldbus Interface: Universal Drive Connectivity

Product Introduction

The SEW DFP21B is a powerful, universal fieldbus interface option for MOVITRAC B frequency inverters. This module connects the drive to higher-level automation systems through PROFIBUS DP and DP-V1 protocols. Additionally, it supports automatic baud rate detection from 9.6 kBd up to 12 MBd.

Specifically, the DFP21B enables seamless integration of MOVITRAC B inverters into PROFIBUS networks. The interface follows IEC 61158 standards for protocol compliance. Furthermore, its external voltage supply via X26 ensures stable communication performance across demanding industrial environments.

Technical Specifications

The PROFIBUS interface type DFP21B delivers reliable communication for industrial automation. First, the external voltage supply at X26 uses DC 24 V with –15% to +20% tolerance. Next, the maximum current draw reaches DC 200 mA, while maximum power consumption stays at 3.4 W.

Moreover, the module supports PROFIBUS DP and DP-V1 protocol variants according to IEC 61158. Its automatic baud rate detection covers 9.6 kBd through 12 MBd. Besides, connection uses a 9-pin D-sub connector with pin assignment per IEC 61158.

Mechanical and Environmental Parameters

The DFP21B gateway module fits directly into the MOVITRAC B option slot. Its compact construction minimizes cabinet space requirements. Meanwhile, the unit operates reliably across standard industrial temperature ranges.

Notably, bus termination is not integrated into the module. Therefore, you must implement termination using a suitable PROFIBUS connector with switchable terminating resistors. This design gives engineers flexibility when configuring network segments.

Installation Guide

Installing the DFP21B PROFIBUS interface requires careful setup and correct addressing. First, disconnect power from the MOVITRAC B frequency inverter. Next, insert the gateway module into the designated option slot. Then, connect the 9-pin D-sub plug to the PROFIBUS network.

After physical installation, set the station address between 1 and 125 using the DIP switches. Additionally, confirm the GSD file SEW_6009.GSD is loaded in your engineering tool. The DP ID number for configuration is 6009hex or 24585 decimal.

Meanwhile, verify the external DC 24 V supply at X26 stays within tolerance. Furthermore, install a PROFIBUS connector with switchable terminating resistors at both network ends. Finally, check that the Set-Prm-UserData length matches the required 3 bytes with hex values 00,00,00.
