Introduction & Technical Overview
The ABB Bailey NSSM01 Super Loop Storage Module is a system-level data buffering and storage component designed for INFI 90 / Net 90 distributed control system architectures. It supports the Super Loop communication framework by temporarily storing and managing data traffic between control modules, helping maintain synchronized and deterministic system performance.
This module is engineered to stabilize data flow in high-load industrial automation environments. It reduces communication bottlenecks by buffering process data, ensuring that time-critical information is not lost or delayed during peak system activity.

Applications
The NSSM01 is widely used in industrial control systems such as power generation plants, petrochemical complexes, oil refineries, and large-scale process automation facilities.
It is typically installed within ABB Bailey control racks as part of the Super Loop communication subsystem. In turbine control systems and boiler automation networks, it helps manage data flow between controllers and I/O modules. It is also used in system expansions and legacy infrastructure maintenance where consistent data throughput is required.
Advantages
The NSSM01 improves system reliability by providing temporary storage for Super Loop communication data, preventing data congestion and ensuring stable system timing.
It enhances deterministic control performance by smoothing communication peaks and maintaining consistent data transfer rates across distributed modules. Its design supports long-term industrial operation in environments with high electrical noise and continuous load conditions.
The module also contributes to improved system scalability by enabling more stable communication behavior in expanded control architectures.
