ABB DSDP170 57160001 – High-Performance Dual Port Communication Processor for Industrial Automation

The ABB DSDP170 57160001 is a dual-port communication processor module designed for integration into ABB’s Symphony Plus and earlier Symphony Harmony distributed control systems (DCS). From my experience supporting automation upgrades in power and process plants, this module typically serves as the backbone for redundant Modbus communications between controllers and field devices. One thing I appreciate is how it maintains stable data flow even under network stress—especially useful when interfacing with legacy RTUs or third-party meters.

You might notice that it doesn’t offer Ethernet on its own, but in many cases, that’s by design—it fits into a larger architecture where serial reliability matters more than speed. It’s commonly used to bridge turbine controls, boiler management systems, and electrical protection relays back to the central controller.

Key Features

• Dual serial ports – Supports two independent RS-485 channels, allowing simultaneous communication with multiple device networks.
• Modbus RTU master/slave capability – Enables flexible integration with drives, meters, and protective relays using standard protocols.
• Redundant system support – Works in hot-standby configurations within the Symphony platform, improving uptime during failures.
• Firmware upgradable – Field updates are possible via service tools, which helps extend lifecycle without hardware swaps.
• Integrated diagnostics – LED indicators provide real-time status on port activity, errors, and system health—useful during commissioning.

Application Fields

This module appears most frequently in mid-sized thermal power stations, water treatment facilities, and oil & gas compression sites where ABB DCS platforms manage critical processes. In practice, it’s often deployed to collect data from motor control centers or synchronize burner sequences in boilers. Some users have also repurposed it in retrofit projects to replace aging PLCs communicating over serial lines.

Advantages & Value

If you’re maintaining an existing ABB control system, sourcing a genuine DSDP170 can prevent costly migrations. Its plug-and-play compatibility means minimal engineering time during replacements. While not feature-rich by modern standards, its stability in noisy industrial environments makes it a reliable choice—especially if you’re avoiding full-scale upgrades. Procurement teams tend to favor it due to lower total cost of ownership compared to gateway-based alternatives.

Installation & Maintenance

Install only in compatible ABB chassis with proper grounding and ventilation—these modules don’t handle heat well in tightly packed cabinets. Keep ambient temperature below 50°C and ensure airflow around the unit. Wiring should use shielded twisted-pair cables with terminations at one end to reduce noise. For maintenance, periodically check terminal tightness and verify communication logs through the control system. Firmware updates require ABB Connect or similar service software and should be done cautiously during planned outages.
