SIEMENS 6SE7090-0XX84-0FF5 — CBP2 PROFIBUS DP Communication Board | SIMOVERT MASTERDRIVES
Engineering Background: The SIMOVERT MASTERDRIVES platform (6SE70 series) is Siemens’ flagship medium-voltage and low-voltage AC drive system, deployed across critical process industries for variable-speed motor control. Within this architecture, the Communication Board PROFIBUS 2 (CBP2) serves as the fieldbus gateway between the drive’s internal control electronics and the plant-level PROFIBUS DP network — enabling real-time parameter access, setpoint transmission, and diagnostic feedback without analog wiring overhead. In distributed control architectures (DCS/SCADA), the CBP2 is the component that makes the drive a first-class network citizen.
Product Positioning: The 6SE7090-0XX84-0FF5 (CBP2) supersedes the original CBP (Communication Board PROFIBUS) with extended baud rate support up to 12 Mbit/s, improved GSD file compatibility, and enhanced diagnostic telegram support (PROFIdrive profile). It is the correct choice when the control system requires cyclic process data exchange (PPO types 1–5) and acyclic parameter access (DPV1 services). It is not a replacement for the CBC (CAN) or CBD (DeviceNet) boards — protocol selection must match the fieldbus standard of the host PLC/DCS.

Engineering Advantages
- For high-speed process control loops, this communication board supports baud rates up to 12 Mbit/s, because the CBP2 hardware implements full PROFIBUS DP physical layer compliance with auto-baud detection — no manual rate configuration required during commissioning.
- For DCS-integrated plants requiring parameter transparency, this communication board enables DPV1 acyclic read/write of all drive parameters, because the CBP2 implements both Class 1 and Class 2 DPV1 master services — allowing online tuning without interrupting cyclic process data exchange.
- For multi-drive PROFIBUS segments, this communication board supports node addresses 1–125 via onboard DIP switches, because address assignment is hardware-defined and survives firmware updates or drive replacement without reconfiguration of the network master.
- For retrofit projects replacing older CBP boards, this communication board maintains backward GSD file compatibility, because the CBP2 GSD file (SI029700.GSD) supports all PPO types defined in the original CBP specification — minimizing PLC program changes during upgrade.
- For safety-critical applications requiring electrical isolation, this communication board provides galvanic isolation between the PROFIBUS bus and drive electronics, because the CBP2 uses optocoupler-based isolation on the DP interface — preventing ground loop interference in long cable runs across plant areas.
- For predictive maintenance programs, this communication board transmits standardized PROFIdrive diagnostic telegrams, because the CBP2 maps drive fault codes and warning bits to PROFIBUS diagnostic data — enabling DCS historians to capture drive health data without additional instrumentation.
System Architecture & Signal Flow
Signal Flow: PROFIBUS DP Master (PLC/DCS) → PROFIBUS cable (shielded twisted pair, max. 1200 m at 187.5 kbit/s) → CBP2 Sub-D connector → Galvanic isolation stage → Drive internal serial interface (SST) → SIMOVERT MASTERDRIVES control board (CU/CB) → Power electronics → Motor. Feedback path: Motor encoder/tachometer → Drive control board → CBP2 → PROFIBUS DP → Master.
Compatible Drive Units (CBP2 slot-compatible):
- SIMOVERT MASTERDRIVES MC (Motion Control): 6SE70xx-xxxx-xxxx — CBP2 installs in option slot A or B
- SIMOVERT MASTERDRIVES VC (Vector Control): 6SE70xx-xxxx-xxxx — same slot mechanical interface
- SIMOVERT MASTERDRIVES FC (Flux Current Control): Compatible with firmware ≥ V3.x
Substitution Conditions: The CBP2 (6SE7090-0XX84-0FF5) directly replaces the CBP (6SE7090-0XX84-0AB0) in all SIMOVERT MASTERDRIVES units. Substitution requires GSD file update in the PROFIBUS master configuration tool (STEP 7 HW Config or TIA Portal). No hardware modification to the drive is required. The CBP2 is not interchangeable with the SLB (SIMOLINK Board) or SCB (Serial Communication Board) — these use different physical interfaces and protocols.

Technical FAQ
Q: Is the CBP2 (6SE7090-0XX84-0FF5) compatible with a Siemens S7-300 PLC acting as PROFIBUS DP master?
A: Yes. The CBP2 operates as a standard PROFIBUS DP slave and is compatible with any DP master that supports the GSD file standard (EN 50170). The S7-300 CP 342-5 or integrated DP port on CPU 315-2 DP can communicate with the CBP2 using the SI029700.GSD file imported into STEP 7 HW Config. PPO type selection must match the PLC function block configuration (e.g., SFB 52/53 for standard drives).
Q: Can the CBP2 replace the original CBP (6SE7090-0XX84-0AB0) without modifying the drive hardware?
A: Yes, the CBP2 is a direct plug-in replacement for the CBP in all SIMOVERT MASTERDRIVES units. The mechanical interface (option slot connector) is identical. The only required change is updating the GSD file in the PROFIBUS master configuration — the CBP2 GSD file (SI029700.GSD) replaces the CBP GSD file. Drive parameters and motor data are retained on the drive’s control board and are unaffected by the board swap.
Q: Does the CBP2 carry PROFIBUS certification, and is it suitable for use in SIL-rated safety applications?
A: The CBP2 is certified by PROFIBUS & PROFINET International (PI) for standard PROFIBUS DP communication. It is CE marked per EMC and Low Voltage Directives. However, the CBP2 does not implement PROFIsafe protocol and is therefore not suitable as the safety communication interface in SIL 2/3 applications. For safety-critical speed control with functional safety requirements, the SIMOVERT MASTERDRIVES Safety Integrated option (with dedicated safe fieldbus interface) must be used. The CBP2 can coexist in the same PROFIBUS segment as PROFIsafe devices but handles only standard process data.
