Product Overview
The ABB Bailey NSSM01 Super Loop Storage Module is a core communication and data management module used in ABB Bailey INFI 90 / Net 90 Distributed Control Systems (DCS).
It plays a central role in the Superloop architecture, where it works as a system node component responsible for storing process-related data, managing communication flow, and coordinating data exchange between loop interface modules and controller systems.
The NSSM01 is typically used as part of a Superloop node structure, often paired with loop interface slave modules to support plant-wide distributed control communication.

Function Description
The NSSM01 is used to manage data and communication flow within the Superloop network structure.
Its main functions include:
- Storing system point and process data used in Superloop communication
- Managing data exchange between loop interface modules and controllers
- Acting as a communication hub within a Superloop node
- Coordinating data transfer across the distributed control network
- Supporting structured communication between system modules
It is not a direct process controller, but a key infrastructure module for data handling and communication management.
Working Principle
The NSSM01 operates as part of a Superloop node system:
- Field and process data is collected by I/O and loop interface modules
- Data is passed into the Superloop node structure
- The NSSM01 stores and organizes this information internally
- It coordinates communication between connected loop and controller modules
- Process data is distributed across the DCS network for control execution
In many configurations, it works together with loop interface slave modules to form a complete Superloop node for real-time data handling.
