Bosch Rexroth CDB01.1C-SE-ENS-ENS-NNN-NNN-S2-S-NN-FW Industrial Network Interface for IndraDrive Systems

Bosch Rexroth CDB01.1C-SE-ENS-ENS-NNN-NNN-S2-S-NN-FW: Industrial Data Link for IndraDrive Smart Factory Networks

In modern smart factory environments, the integrity of the industrial data link between field devices and upper-level control systems determines the efficiency, safety, and scalability of the entire production line. The Bosch Rexroth CDB01.1C-SE-ENS-ENS-NNN-NNN-S2-S-NN-FW is a high-performance axes communication card engineered for the IndraDrive series, delivering real-time SERCOS III protocol connectivity across multi-axis servo drive architectures. This module serves as the critical network interface node that bridges servo drives, PLC controllers, remote I/O systems, HMI panels, and SCADA platforms — enabling seamless, deterministic data flow from signal acquisition at the field level all the way to enterprise-level monitoring and diagnostics.

Designed for demanding industrial automation applications, the CDB01.1C-SE-ENS-ENS-NNN-NNN-S2-S-NN-FW integrates dual ENS (EtherNet SERCOS) ports, allowing ring topology redundancy and high-speed cyclic data exchange between the IndraDrive controller and connected axes. Whether deployed in CNC machining centers, robotic assembly lines, packaging automation, or precision motion control systems, this axes card ensures sub-millisecond synchronization across all networked drive nodes — a fundamental requirement for coordinated multi-axis motion in Industry 4.0 environments.

Compatibility & Integration Notes

Connected Automation Data Flow

The CDB01.1C-SE-ENS-ENS-NNN-NNN-S2-S-NN-FW sits at the heart of the IndraDrive communication architecture. In a typical smart factory deployment, field-level sensors and encoders feed real-time position, velocity, and torque data into IndraDrive servo drives such as the HCS02 and HCS03 power supply units, which work in tandem with the HMS01 and HMD01 double-axis modules. The CDB01 axes card aggregates this drive-level data and transmits it over the SERCOS III ring to the motion controller — typically an IndraControl VPB40 or IndraControl VPC21 — where the IndraLogic L45 PLC runtime processes the cyclic data and executes coordinated motion programs.

Upstream, the IndraControl platform connects via OPC-UA or Ethernet to SCADA systems and HMI panels, enabling operators to visualize axis positions, drive states, alarm conditions, and energy consumption in real time. The CSB01 single-axis module and CSH01 high-performance axes card complement the CDB01 in mixed-axis configurations, where different motion profiles — interpolated, synchronized, or cam-based — must coexist on the same SERCOS III network segment. For applications requiring protocol bridging to legacy Profibus or Modbus RTU field devices, the Rexroth IndraControl XM22 gateway module handles protocol conversion transparently, ensuring that older sensors and actuators remain fully integrated into the modern SERCOS III data backbone without disrupting network timing.

Remote I/O expansion is handled through Rexroth’s Inline I/O modules connected via the SERCOS III service channel, while variable frequency drives and spindle inverters — including the IndraDrive Cs compact series — receive velocity and torque setpoints directly from the CDB01 axes card’s cyclic output data. This end-to-end data chain, from encoder signal acquisition through drive control to SCADA visualization, is what makes the CDB01.1C-SE-ENS-ENS-NNN-NNN-S2-S-NN-FW an indispensable component in high-performance industrial automation networks.

Solving Data Isolation in Industrial Sites

One of the most persistent challenges in industrial automation is data isolation — the condition where field devices, drives, and controllers operate on incompatible protocols, preventing unified monitoring, coordinated control, and transparent production reporting. The CDB01.1C-SE-ENS-ENS-NNN-NNN-S2-S-NN-FW directly addresses this challenge by providing a standardized SERCOS III communication layer that unifies all IndraDrive axes under a single, deterministic network. This eliminates the latency and data loss associated with protocol mismatches and proprietary point-to-point wiring.

For facilities transitioning from legacy Profibus or CANopen architectures, the CDB01 axes card enables a phased migration strategy: existing drives can be replaced with IndraDrive units equipped with the CDB01 card, while the IndraControl gateway layer handles backward compatibility with legacy field devices. This approach preserves capital investment while progressively modernizing the network infrastructure. Remote monitoring and diagnostics become immediately available once the SERCOS III ring is established — maintenance engineers can access drive fault logs, axis performance trends, and network health metrics from any SCADA or HMI terminal on the plant network, dramatically reducing mean time to repair (MTTR) and unplanned downtime.

Production line transparency is further enhanced through the CDB01’s support for acyclic SERCOS III service channel communication, which allows parameter read/write operations, firmware updates, and diagnostic queries to be performed without interrupting the real-time cyclic data exchange. This non-intrusive diagnostic capability is critical for 24/7 manufacturing environments where stopping the line for maintenance is not an option. System scalability is equally straightforward: additional IndraDrive axes can be added to the SERCOS III ring at any time, with the CDB01 axes card automatically accommodating new nodes during the network initialization phase — no rewiring, no protocol reconfiguration, no production interruption.

Industrial Connectivity FAQ

Q1: What is the communication latency of the CDB01.1C-SE-ENS-ENS-NNN-NNN-S2-S-NN-FW on a SERCOS III network?
The CDB01 axes card supports SERCOS III cycle times as low as 62.5 microseconds, delivering deterministic real-time communication with jitter well below 1 microsecond. This makes it suitable for the most demanding multi-axis synchronization applications, including electronic gearing, cam profiling, and high-speed pick-and-place robotics.

Q2: Is the CDB01.1C-SE-ENS-ENS-NNN-NNN-S2-S-NN-FW compatible with non-Rexroth SERCOS III controllers?
Yes. SERCOS III is an open IEC 61491 standard, and the CDB01 axes card is compatible with any SERCOS III master controller that conforms to the standard specification. However, full parameter access and IndraDrive-specific diagnostic features are best utilized with Bosch Rexroth IndraControl or IndraWorks engineering software environments.

Q3: How is network stability ensured in ring topology deployments?
The dual ENS ports on the CDB01 support SERCOS III ring redundancy. In the event of a cable break or node failure, the network automatically reconfigures to line topology within one communication cycle, maintaining data integrity and preventing production stoppage. This hot-plug redundancy is managed transparently by the SERCOS III master without operator intervention.

Q4: What testing and warranty coverage is provided with this unit?
Every CDB01.1C-SE-ENS-ENS-NNN-NNN-S2-S-NN-FW unit is fully tested and verified before shipment, including SERCOS III communication initialization, cyclic data exchange validation, and firmware version confirmation. All units are covered by a warranty terms confirmed during quotation against manufacturing defects and functional failures. Availability is confirmed via RFQ for shipment arranged after confirmation with global shipping support.
