Description

3BHT300057R1: Product Overview
The 3BHT300057R1 is a fieldbus communication interface module within ABB’s Symphony Harmony distributed control system (DCS) family, designed to enable Profibus DP protocol connectivity between DCS controllers and peripheral devices. Its role is to act as a protocol gateway, positioned in Symphony Harmony I/O racks to bridge the controller (e.g., AC800M) with Profibus DP slave devices such as variable frequency drives (VFDs), smart meters, and remote I/O stations. In process industries like power generation, chemical manufacturing, and oil refining, it facilitates real-time data exchange for coordinated control of drives, monitoring of device status, and integration of third-party equipment into the DCS architecture.
Functionally, the module supports Profibus DP V1 (up to 12 Mbps), handling cyclic I/O data (inputs/outputs) and acyclic messages (diagnostics, configuration). It processes 16-byte I/O data blocks per slave, ensuring deterministic communication for time-sensitive applications like motor speed control. As part of the Symphony Harmony platform, it leverages modular expandability, compatibility with ABB Control Builder M engineering software, and native backplane integration with S800 I/O modules. Benefits include reduced wiring complexity (eliminating parallel control lines), simplified system scalability via plug-and-play installation, and unified configuration workflows that accelerate commissioning.

Core Features & Customer Value​
Profibus DP V1 integration for industrial drives: The module’s support for Profibus DP V1 enables advanced drive control (e.g., parameterization, fault diagnostics) beyond basic I/O exchange. For customers with VFD-driven pumps or fans, this allows direct integration of drive status (e.g., overload, speed deviation) into the DCS, eliminating separate monitoring systems. The 12 Mbps baud rate ensures low-latency communication for applications like turbine governor control, where response time impacts grid stability.
Seamless Symphony Harmony ecosystem compatibility: As a native Symphony Harmony component, the module connects via the rack backplane, avoiding external gateways and ensuring deterministic data transfer. Engineers configure slave devices and map I/O data using ABB Control Builder M, reducing setup time by 15-20% compared to third-party adapters. For example, in a wastewater treatment plant, it can link a Profibus DP-linked sludge pump VFD to the DCS, enabling remote speed adjustment based on flow sensor feedback.
Robust design for harsh environments: Galvanic isolation (500V AC) protects the DCS from ground loops and transient voltages common in motor control centers (MCCs). The -25°C cold-start capability supports outdoor installations (e.g., remote pump stations), while compact dimensions (25mm width) optimize I/O rack space. For procurement teams, this extends service life and lowers lifecycle costs versus non-industrial communication modules.

Typical Applications​
In a power plant’s boiler feedwater system, the module connects a Symphony Harmony controller to a Profibus DP VFD driving a feedwater pump. It transmits speed setpoints from the DCS and receives pump status (e.g., bearing temperature, current draw) for predictive maintenance, reducing unplanned outages.
At a chemical plant’s polymerization reactor, it interfaces with a Profibus DP smart meter measuring reactant flow. The module relays flow data to the DCS for batch control, while diagnostics alert operators to meter calibration needs, ensuring product quality consistency.
In an oil refinery’s compressor station, the module links a Profibus DP remote I/O station (monitoring vibration sensors) to the DCS. This enables real-time vibration trending, helping detect bearing wear before catastrophic failure.
