Product Introduction
The ABB DSPC172H (order code 57310001-MP) is a high-performance processor module designed for ABB’s AC 800M distributed control system. As an enhanced core of the Master Piece series, it serves as the “super brain” of the control system, handling high-speed computation, multi-task scheduling, and full-protocol communication for both process automation and discrete control applications.
Compared to the base DSPC172 model, the DSPC172H delivers a significant performance leap with doubled memory capacity (256 MB RAM + 128 MB Flash) and an enhanced 32-bit processor running at higher frequency. This allows it to simultaneously run multiple control algorithms and efficiently handle large-scale I/O networking, making it ideal for complex chemical, power generation, and metallurgical systems with high-concurrency instruction requirements.
The module features comprehensive communication capabilities with dual Ethernet ports supporting TCP/IP, EtherNet/IP, and PROFINET protocols, along with RS232, RS485, and Profibus DP interfaces. This full-protocol support enables direct connection to HMIs, PLCs, remote I/O stations, and enterprise management systems without requiring additional gateways, achieving bidirectional data flow between field control and cloud-level systems.
One of the DSPC172H’s key advantages is its ability to support both fast-scan logic (such as motor control) and slow-scan logic (such as analog regulation) within a single controller. This “dual-capability” architecture reduces system complexity and hardware investment by eliminating the need for separate controllers for different control speeds.
The module supports modular redundancy configuration, paired with comprehensive alarm management and system diagnostics for rapid fault localization. Its battery-backed real-time clock ensures time-stamped data integrity even during power outages. With an MTBF exceeding 500,000 hours and industrial-grade design rated for -25°C to +65°C operation, the DSPC172H delivers the reliability required for continuous production environments.
For maintenance teams supporting AC 800M installations, the DSPC172H is a direct drop-in replacement for failed or degraded processor modules. Its standardized DIN rail mount form factor ensures compatibility with existing system configurations, avoiding the need for mechanical modifications or rewiring. When replacing a DSPC172H, always verify that the order code (57310001-MP) matches the original board to ensure full compatibility with the system’s firmware and hardware configuration.
QA & Testing SOP
Every unit goes through a structured verification process before shipment:
- Visual Inspection: Check the PCB for cracks, burnt components, corrosion on connector pins, and physical damage to the board. Verify that all surface-mount and through-hole components are securely soldered with no cold joints or solder bridges. Inspect the battery holder for the real-time clock to ensure it is intact and properly seated.
- Connector Pin Verification: Inspect all connector pins (Ethernet ports, serial ports, backplane connectors) for straightness, corrosion, or bending. Bent pins cause poor contact, leading to intermittent communication failures or complete module malfunction.
- Power-On Self-Test: Apply 24VDC power and verify that the module’s status LEDs indicate normal boot sequence. Check for any abnormal heating of components during the initial power-on. Verify that the module completes its self-diagnostic routine without errors.
- Memory Read/Write Test: Where test infrastructure allows, perform read/write tests on both RAM and Flash memory to verify that all memory cells are functioning correctly. Write test patterns to memory and read them back to confirm data integrity across the full memory address range.
- Communication Port Test: Verify that all communication interfaces (dual Ethernet, RS232, RS485, Profibus DP) are functional. Test network connectivity, serial communication, and protocol handshake to ensure the module can communicate with connected devices.
- Real-Time Clock Verification: Verify that the battery-backed real-time clock is functioning correctly and retains time settings after power cycling.
- Anti-Counterfeit & Packaging: Verify authenticity markings on the PCB and components. Each unit is shipped in anti-static protective packaging with desiccant to prevent moisture absorption and connector oxidation during transit.
Installation Pitfalls & Guide
Installing or replacing a high-performance CPU module requires careful attention to safety procedures and proper handling.
❗ Power-Down Before Installation: Always disconnect power to the AC 800M controller chassis before removing or inserting the DSPC172H module. CPU modules should be replaced with power off to prevent electrical damage to the module or the controller’s backplane connector.
❗ Anti-Static Protection: Always wear an anti-static wrist strap when handling the DSPC172H module. The PCB contains sensitive electronic components that can be damaged by electrostatic discharge (ESD). Handle the module by its edges only, avoiding contact with components or connector pins.
❗ Correct Module Orientation: The DSPC172H must be inserted into the AC 800M controller’s CPU slot with the correct orientation. Forcing the module into the wrong orientation can damage the connector pins and the controller’s backplane. Align the module’s connector with the slot guides and push firmly and evenly until fully seated.
❗ Heat Dissipation Clearance: Ensure at least 55mm of clearance above and below the module for proper heat dissipation. Insufficient clearance can cause the module to overheat, leading to performance degradation or premature failure.
❗ Firmware and Configuration Backup: Before replacing the DSPC172H, back up the controller’s program, configuration data, and parameter settings to an external storage device. After installing the replacement module, you may need to download the control program and configuration from your backup.
4-Step Replacement Guide:
- Pre-install: Document the existing controller configuration, including controller type, firmware version, and any custom parameters. Back up the controller’s program and configuration data to an external storage device. Verify the replacement module’s order code (57310001-MP) matches the original. Prepare anti-static protection, tools, and a laptop with the necessary engineering software.
- Removal: Disconnect power to the AC 800M controller chassis. Wear an anti-static wrist strap. If the module has a retention clip or screw, loosen it before removal. Gently pull the module straight out of the CPU slot. Inspect the controller’s CPU slot connector for damage or debris.
- Install: Align the new DSPC172H’s connector with the CPU slot guides. Push firmly and evenly until fully seated. Secure the module with the retention clip or screw if applicable. Verify that the module is fully seated and locked in place. Ensure adequate heat dissipation clearance around the module.
- Power-on Test: Apply power to the AC 800M controller chassis. Enter the controller’s diagnostic screen and verify that the processor module is recognized with no fault codes. Check the module status LEDs to confirm normal operation. Download the control program and configuration from your backup if necessary. Monitor the controller for several minutes to confirm stable operation, checking CPU load, memory usage, and communication status.

This makes it suitable for large-scale distributed control applications where extensive I/O networking is required.
5. What are common symptoms of a failing DSPC172H processor module? Common symptoms include: Controller not booting or stuck in boot loop; communication failures with remote I/O or HMIs; unexpected controller resets or trips; high CPU load warnings; memory errors or corruption; real-time clock losing time after power cycles; and fault codes related to processor or communication failures. If you’re experiencing any of these symptoms, check the controller’s diagnostic screen for specific error codes.
6. What’s the difference between New Surplus and Refurbished for processor modules? We supply this unit as New Original (New Surplus)—unused, original factory stock. This comes with a standard 12-month warranty. Refurbished processor modules carry risks including degraded memory cells from prior use, weakened processor performance from previous thermal stress, and latent failures that may only manifest under full load conditions. For a module that serves as the central brain of your control system, new surplus is the safer choice.
