BOSCH Rexroth BM-DP12 (1070075887-202) – PROFIBUS DP Expansion Module | Indramat Drive Platform
Engineering Background: The BM-DP12 is a PROFIBUS DP communication expansion module developed by BOSCH Rexroth under the Indramat drive controller platform. It enables seamless integration of Rexroth servo and spindle drives into PROFIBUS DP fieldbus networks, a standard widely adopted in European and Asian manufacturing automation since the mid-1990s. Part number 1070075887-202 identifies the specific hardware revision with enhanced EMC shielding and extended temperature tolerance.
Product Positioning: Designed for procurement engineers and maintenance teams managing legacy or active Rexroth Indramat drive systems, the BM-DP12 provides a plug-in fieldbus interface that eliminates the need for full drive replacement when upgrading communication architecture. It is the preferred sourcing target for OEM machine builders and system integrators maintaining PROFIBUS-based production lines.

Engineering Advantages
- Drop-in Compatibility: Plug-in module design requires no drive firmware modification; recognized automatically by host drive on power-up.
- Deterministic Communication: PROFIBUS DP cyclic data exchange ensures <1 ms update cycles at 12 Mbit/s for real-time torque and speed control.
- Revision 202 Enhancements: Improved EMC filtering on the PROFIBUS interface and wider operating temperature range vs. earlier -201 revision.
- Diagnostic Transparency: Module status LEDs (BF, SF) provide immediate fieldbus fault indication without requiring a laptop or programming tool.
- Long Service Life: Industrial-grade components rated for continuous 24/7 operation in harsh factory environments.
System Architecture & Signal Flow
The BM-DP12 inserts into the option slot of compatible Rexroth Indramat drive controllers. The host drive’s internal bus provides power and data exchange to the module. On the fieldbus side, the DB9 connector links to the PROFIBUS DP segment. The PLC master (DP master class 1) cyclically exchanges process data (setpoints, actual values, status words) with the drive acting as a DP slave. Acyclic parameter access (DPV1) is supported for drive parameterization via the fieldbus without interrupting cyclic operation.

Technical FAQ
Q: Is the BM-DP12 compatible with Rexroth DIAX04 drives?
A: Compatibility depends on the specific DIAX04 variant and option slot configuration. Contact us with your drive nameplate data for confirmation.
Q: Can this module be used with a Siemens S7-300/400 PROFIBUS master?
A: Yes. The BM-DP12 is a standard PROFIBUS DP slave and is compatible with any DP master class 1 controller, including Siemens S7, Beckhoff TwinCAT, and B&R Automation Studio.
Q: What is the difference between revision -201 and -202?
A: Revision -202 incorporates enhanced EMC suppression components and an extended operating temperature ceiling. It is a direct drop-in replacement for -201 in all documented applications.
Q: Do you provide the GSD file for PROFIBUS configuration?
A: Yes. The Rexroth GSD file for BM-DP12 is available upon request or can be downloaded from the Bosch Rexroth support portal.
Q: Is this a new or refurbished unit?
A: Units are sourced as genuine OEM pulls or new-old-stock (NOS). Condition is clearly stated on the product listing. All units pass pre-shipment inspection.
