Product Overview

The NMBP-01 is a specialized communication gateway engineered by ABB to bridge the gap between legacy Distributed Control Systems (DCS) and modern industrial networks. Specifically designed for the Bailey Net 90 and Infi 90 series, this adapter facilitates high-speed data translation between the Modbus Plus protocol and standard control infrastructures. By enabling seamless interoperability, the NMBP-01 allows plant operators to integrate third-party PLCs, variable speed drives, and power monitors into a unified Bailey control environment. Its architecture is optimized for real-time arbitration, ensuring that time-critical process data is transmitted with minimal latency across the network backplane.

Industrial Implementation and Network Roles

The NMBP-01 is an essential utility for facilities looking to modernize their control architecture without replacing their entire legacy DCS backbone.

• Legacy System Integration Connecting modern Schneider Electric or third-party Modbus Plus devices directly into the Infi 90 control loop.

• Remote Asset Monitoring Transmitting status data from geographically dispersed field devices back to the central DCS operator stations via high-speed tunneling.

• Motor Control Center (MCC) Networking Facilitating the exchange of energy metrics and fault codes between intelligent motor starters and the primary process controller.

• Redundant Communication Paths Establishing secondary data links to ensure process visibility in the event of a primary network failure.

• Protocol Conversion Seamlessly mapping Modbus registers to Bailey function blocks for easier engineering and configuration in the Composer or WinTools environment.
