ABB PDP800 Symphony Plus PROFIBUS‑DP Master Module

PDP800 is a PROFIBUS‑DP master communication module for ABB Symphony Plus DCS system. It serves as field‑bus interface for HC800 controller, realizing high‑speed data exchange between DCS controller and PROFIBUS‑DP remote I/O, drives, transmitters and other field‑bus slave devices.

This hot‑swappable module supports PROFIBUS‑DP V0/V1 protocol, and can run in redundant configuration to enhance system availability. Adopting standard DIN‑rail installation, it is widely deployed in power, petrochemical and pulp‑paper process‑automation control cabinets.
