Description
The ABB PDP800 is a high-performance Profibus DP Communication Module designed for the AC 800M controller and the S800 I/O system family. It serves as a master or slave interface, enabling the controller to exchange data with a wide variety of Profibus-compatible devices, including motor starters, field instruments, and remote I/O stations.

Country of Origin
This industrial communication module is engineered and manufactured by ABB in Sweden, adhering to rigorous European standards for industrial networking and electromagnetic compatibility.
Application Fields
The PDP800 is a versatile communication bridge used in various industrial environments:
- Manufacturing Automation: Connecting ABB controllers to third-party motor drives (VFDs) and sensors.
- Process Industries: Interfacing with intelligent field devices in chemical and pharmaceutical plants.
- Water & Wastewater: Integrating distributed pump stations and flowmeters into a central SCADA system.
- Power Generation: Communicating with protection relays and electrical switchgear.
- Oil & Gas: Managing data from remote I/O manifolds in hazardous or offshore locations.
Product Usage Instructions
- Mounting: Snap the PDP800 onto the designated Termination Unit (TU). Ensure the module is firmly seated and the locking mechanism is engaged.
- Addressing: Set the Profibus station address using the rotary switches on the front of the module (typically ranges from 00 to 99) or via the system software.
- Cabling: Use high-quality, shielded Profibus DP cable (Purple jacket). Ensure the BNC/D-sub connectors are properly terminated with 220-ohm resistors at both ends of the segment.
- Software Configuration: Within the ABB Control Builder M or 800xA engineering environment, add the PDP800 to the hardware tree and define the GSD files for the connected slave devices.
- Diagnostic LEDs: Monitor the status lights: “Run” (Green) indicates normal operation, while “Fault” (Red) suggests a configuration mismatch or cable break.
Product Technical Description
The PDP800 functions as an intelligent interface that offloads the communication processing from the main AC 800M CPU. It utilizes a dedicated communication processor to handle the high-speed Profibus DP token-passing protocol. Technically, it supports cyclic data exchange for real-time control and acyclic data exchange for device configuration and diagnostics (DP-V1). When used in a redundant configuration, two PDP800 modules work in a primary/backup mode; if the primary module or cable fails, the system performs a “bumpless” switchover to the backup module to maintain process continuity.
Q&A (Common Questions)
- Q: Can I use the PDP800 as a slave module?
- A: While primarily used as a Master in AC 800M systems, its role depends on the hardware configuration and the specific software library used.
- Q: What is the maximum cable length supported?
- A: At the highest speed (12 Mbps), the limit is 100 meters per segment. At 9.6 kbps, the distance can extend up to 1,200 meters without repeaters.
- Q: Do I need a GSD file for the PDP800 itself?
- A: No, the ABB engineering software already contains the definitions for ABB-native modules. You only need GSD files for third-party slave devices.
- Q: Is the PDP800 hot-swappable?
- A: Yes, in a redundant S800 I/O configuration, the module can be replaced while the system is energized without interrupting the network traffic.
