Product Overview
The ABB Bailey NSIM01 Serial Interface Module is a communication interface module used in ABB Bailey INFI 90 / Net 90 Distributed Control Systems (DCS). It is designed to handle serial communication between the DCS system and external devices or engineering stations, enabling reliable data exchange over RS-232 or similar serial protocols.
This module is typically used as part of a Plant Loop node structure, working alongside loop interface and point table modules to support system communication and data transfer.

Function Description
The NSIM01 is used to enable serial data communication within ABB Bailey control systems.
Its main functions include:
- Providing RS-232 serial communication ports for system connectivity
- Transmitting process and configuration data to external systems
- Supporting engineering workstation communication links
- Acting as an interface between Plant Loop data structures and external devices
- Enabling data exchange between DCS and supervisory/monitoring systems
It does not execute control logic; it operates strictly as a communication interface module.
Working Principle
The NSIM01 operates as part of the Plant Loop communication architecture:
- Process data is generated by controllers and I/O modules
- Data is structured by system modules (e.g., point table modules)
- NSIM01 transmits this data via serial communication channels
- External systems receive or send data through RS-232 ports
- Feedback or configuration data is returned into the DCS system
This allows external systems to interact with the ABB Bailey control environment.
