The ABB Bailey NSSM01 SuperLoop Storage Module is a communication and data management module used in the ABB Bailey INFI 90 / Net 90 Distributed Control System (DCS). It operates within the SuperLoop architecture and serves as a central storage and communication management component for process data exchanged between operator stations, engineering workstations, and control modules.
The NSSM01 maintains communication information tables, interprets data flow across the SuperLoop network, and coordinates bus communication between connected modules. It plays a critical role in ensuring stable, synchronized, and efficient data handling throughout the distributed control system.
This module is widely deployed in legacy ABB Bailey systems across power generation, oil & gas, petrochemical, water treatment, and manufacturing industries.
