PROFIBUS/MPI Industrial Networking Solution – SIEMENS 6GK1561-2AA00 | CP 5612 A2
Where This Product Is Used
The SIEMENS CP 5612 A2 (6GK1561-2AA00) is a PCIe-based communication processor engineered for demanding industrial environments where a PC or server must participate directly in PROFIBUS DP or MPI networks. Typical deployment scenarios include:
- Automotive Assembly Lines – Connects supervisory PCs to SIMATIC S7 PLCs controlling robotic welding cells and conveyor systems via PROFIBUS DP.
- Process Plant SCADA Stations – Integrates engineering workstations into MPI segments for live parameter monitoring and program upload/download in chemical and petrochemical plants.
- Machine Tool & CNC Environments – Provides a high-speed, deterministic link between CNC controllers and SIMATIC-based safety PLCs on the shop floor.
- Water & Wastewater Treatment – Enables operator stations to communicate with distributed PROFIBUS DP field devices (drives, valves, sensors) across large plant footprints.
- Power Generation & Utilities – Supports real-time data acquisition from PROFIBUS-connected protection relays and energy meters into historian servers.
- Building Automation & HVAC – Links BMS servers to SIMATIC ET 200 distributed I/O stations for centralized monitoring of HVAC, lighting, and access control.

Why Engineers Specify This Model
- Native SIMATIC NET Integration – Works seamlessly with STEP 7 and TIA Portal without third-party middleware, reducing commissioning time.
- Full 12 Mbit/s PROFIBUS DP Speed – Supports the highest standard baud rate, ensuring cycle-time compatibility with fast I/O devices and drives.
- PCIe x1 Low-Profile Form Factor – Fits both full-height and low-profile industrial PCs and rack servers; includes both bracket types.
- Dual Protocol Support (DP + MPI) – A single card covers both PROFIBUS DP field-level communication and MPI programming/monitoring, eliminating the need for a separate programming adapter.
- Proven Long-Term Availability – Established SIEMENS catalog item with documented hardware revision (A5E39492452-AA), simplifying spare-parts planning and lifecycle management.
- Deterministic Real-Time Performance – Offloads PROFIBUS protocol processing from the host CPU, ensuring consistent cycle times even under high PC load.

Application-Specific FAQ
Q: Can the CP 5612 A2 operate as a PROFIBUS DP slave?
A: Yes. The card supports both DP master (Class 1 & 2) and DP slave modes, configurable via SIMATIC NET software.
Q: Is this card compatible with TIA Portal V17/V18/V19?
A: Yes, provided the corresponding SIMATIC NET CP 5612 driver package for the TIA Portal version is installed. Always verify the SIMATIC NET compatibility matrix for your specific TIA Portal release.
Q: Can I use this card for S7 online programming (PG/PC function)?
A: Yes. The MPI interface allows direct STEP 7 / TIA Portal online access to SIMATIC S7-300/400 CPUs without a separate MPI adapter.
Q: Does it work in a virtual machine (VM)?
A: PCIe passthrough to a VM is technically possible but not officially supported by SIEMENS for real-time PROFIBUS DP applications. Physical host installation is recommended for production use.
Q: What is the maximum number of DP slaves supported?
A: Up to 125 DP slaves per PROFIBUS segment (per PROFIBUS DP specification); practical limits depend on baud rate and network topology.
Q: Is a low-profile bracket included?
A: Yes. The 6GK1561-2AA00 ships with both a standard full-height bracket and a low-profile bracket for compact industrial PCs.
