Product Overview
The ABB Bailey NLIM02 Loop Interface Module is a core communication module used in ABB Bailey INFI 90 / Net 90 Distributed Control Systems (DCS). It is designed to manage and coordinate data exchange between control system nodes over the INFI-Net or Plant Loop network.
This module plays a critical role in system-level communication routing, ensuring that data from controllers, I/O modules, and other system components is correctly transmitted across the industrial control network.
The NLIM02 is typically used in distributed control architectures, where multiple modules must communicate reliably over long distances in harsh industrial environments.

Function and Working Principle
The NLIM02 Loop Interface Module is responsible for managing communication between different nodes in an ABB Bailey distributed control system.
In operation, it collects data from connected system modules and transmits it across the Plant Loop or INFI-Net network. It also receives incoming data from other nodes and distributes it to local system components.
This ensures that all controllers and I/O modules within the system remain synchronized and can operate as part of a unified control architecture.
The module is often used together with other interface components to maintain stable communication flow across the entire DCS network.
