The ABB PPD113B03-26-100100 (Part Number: 3BHE023584R2625) is a high-performance central processing unit (CPU) module belonging to the AC 800PEC (Power Electronic Controller) family. It represents the pinnacle of ABB’s high-speed control technology, specifically engineered to bridge the gap between extremely fast power electronics control (microsecond range) and traditional industrial process control (millisecond range).
This module is a core component in demanding electrical applications where precision and speed are non-negotiable, often serving as the primary control unit for excitation systems, high-power converters, and large-scale motor drives.
Product Introduction
The AC 800PEC controller is a modular, high-end system that combines the capabilities of a high-speed controller with the functionality of a standard PLC. The PPD113B03 is designed to handle very fast analog and digital I/O processing while simultaneously managing lower-speed ancillary tasks like cooling circuit monitoring and plant-wide communication.
By integrating Field Programmable Gate Array (FPGA) technology alongside a powerful 32-bit RISC processor, the PPD113B03 can execute control loops with cycle times as low as 25 μs. It is optimized for model-based design, allowing engineers to deploy algorithms directly from MATLAB®/Simulink® environments.

Product Technical Description
The module architecture is built for deterministic performance. It features a robust, fan-less design that ensures a long life cycle in harsh industrial conditions.
- Dual-Layer Processing: The CPU handles standard logic and communication, while the FPGA manages the high-speed bit-level tasks, such as firing pulses for thyristors and high-frequency PWM (Pulse Width Modulation).
- Optical Connectivity: To eliminate electromagnetic interference (EMI) issues in high-power environments, the PPD113B03 communicates with peripheral I/O modules via fiber-optic links.
- Redundancy Support: The AC 800PEC system allows for redundant CPU configurations to ensure plant availability even in the event of hardware failure.
Product Usage Instructions
1. Hardware Installation
- Mount the module on a standard 35mm DIN rail within a grounded metal enclosure.
- Ensure adequate clearance for wiring and fiber-optic cable bend radii.
- Connect a stabilized 24V DC power supply. It is highly recommended to use a redundant power feed to the backplane to prevent accidental shutdowns.
2. Communication Setup
- Ethernet: Use the onboard Ethernet ports for connection to the plant network and the Control Builder M engineering tool.
- Serial Interface: The RS-232 port is primarily used for local service access via the PECView diagnostic tool.
- Grounding: Strict adherence to single-point grounding principles is required to suppress EMI, especially when the module is near high-power converters.
3. Software Configuration
- Install the ABB AC 800PEC Toolbox to access hardware-specific functions.
- Use Control Builder M for standard process logic (IEC 61131-3 languages).
- For fast control loops, utilize Simulink® with Real-Time Workshop® to generate C-code that is directly downloadable to the controller.
4. Maintenance and Diagnostics
- Monitor the LED indicators on the front panel: A green “Run” LED indicates normal execution; a red “Err” LED signifies a hardware or program fault.
- Perform periodic backups of the application using the “Backup and Restore” functions in the engineering software.

Product Q&A (Common Questions)
Q: Can I replace a PPD113B03-26-100100 with a different B01 or B02 version? A: While they are in the same family, different versions (B01, B02, B03) have varying FPGA capacities, memory sizes, and communication port configurations. You must verify compatibility with your specific system firmware and application code before swapping.
Q: Does the module require a separate cooling fan? A: No. The PPD113B03 is designed for convection cooling. However, the cabinet temperature must be maintained within the specified range (max 60°C) to prevent thermal throttling.
Q: How do I recover the system if the “Error” LED is solid red? A: A solid red LED usually indicates a boot-up failure or a fatal software exception. You should connect via the RS-232 service port and use PECView to retrieve the internal log files to identify the root cause.
Q: Is the PPD113B03 compatible with third-party fieldbus protocols? A: Yes. Through the Communication Expansion Bus (CEX), the AC 800PEC can interface with third-party Anybus-S modules for protocols such as Profibus DP, Modbus TCP, and others.
Q: What happens if a fiber-optic link is broken? A: The controller will typically trigger a system alarm. If the link is critical for a fast control loop (e.g., converter firing), the system will initiate a protective trip to prevent hardware damage.
