Description
The Siemens 6SE6400-1PB00-0AA0 is a Profibus DP option module (CBP — Communication Board Profibus) for the MICROMASTER 4 (MM420 / MM430 / MM440) inverter / drive series. It plugs into the option slot on the drive’s control unit, enabling the inverter to operate as a Profibus DP slave on a Profibus DP network — communicating with Siemens S7-300/400/1200 (via Profibus DP master module), S5, or any other Profibus DP master (e.g., ABB, Rockwell with Profibus master).
Related part numbers:
- 6SE6400-1PB00-0AA0 → Profibus DP module for MM4 (most common — CBP = Comm Board Profibus)
- 6SE6400-0BP00-0AA0 / 0AA1 → Sometimes listed as the same CBP board or early/alternate packaging — functionally identical to 6SE6400-1PB00-0AA0 for MM4. Always verify against your drive manual — MM4 uses the -1PB00-… board. (Note: MM3 used a different add-on card; do NOT confuse with SINAMICS G120 CU240/CU250 option boards which are NOT interchangeable.)
The module supports Profibus DP-V0 / DP-V1, with PPO type 1–5 selectable via GSD file in the master configuration software (STEP 7 / TIA Portal with GSD or Drive ES). It provides diagnostic LEDs (BF = Bus Failure, SF = System Fault) and a 9-pin D-Sub Profibus connector.
Key Features
- Protocol: Profibus DP (DP-V0 / DP-V1)
- Baud Rate: 9.6 kbps … 12 Mbps (auto-detect)
- PPO Types: 1–5 (Process Data Object — control word / status word / setpoint / actual value)
- Connector: 9-pin Sub-D female (Profibus standard)
- Termination: 220 Ω + switchable active termination (via DIP or software — usually external terminator resistor recommended at bus ends)
- Installation: Plugs into MM420 / MM430 / MM440 option slot (Slot A or B — check drive manual; most MM4 have one option slot for this board)
- Country of Origin: Germany

Warranty & After-Sales
- Factory new units: 12 months warranty
- Refurbished units: 3-6 months warranty (Profibus link & PPO communication test on MM4 simulator)
- Technical support for:
- GSD file installation (STEP 7 / TIA Portal — add MM4 GSD)
- PPO type selection & drive parameterization (P0918 station addr, P0700=6 (Profibus/CB), P1000=6, P2051[..] for extra PKW if needed)
- Profibus cabling & termination check (A/B polarity, 220 Ω ends)
- Fault LED interpretation (BUSF = no link / wrong baud; check master config & cable)
- Cross-check if you actually need SINAMICS G120 Profibus board (6SL3255-0AA00-4CA1 — NOT same!)
