The ABB Bailey NPTM01 is a vital communication and memory mapping module within the Bailey Network 90 and INFI 90 Distributed Control Systems (DCS). As a Point Table Module, its primary role is to handle real-time data mapping and coordination between I/O modules and the control processors, ensuring consistent and synchronized data communication throughout the system.

Designed for high-reliability industrial automation applications, the NPTM01 acts as an intermediary that updates and maintains a dynamic “point table” — essentially a table of variables or signals (process values, alarms, statuses) accessible by the DCS processors. This module allows for efficient data retrieval, storage, and dissemination, playing a pivotal role in multi-loop control, logic execution, and real-time decision-making within plant automation.

As part of ABB Bailey’s legacy system line-up, the NPTM01 remains critical in process-heavy environments such as power plants, chemical processing facilities, pulp and paper industries, and other industries where legacy DCS platforms are still actively maintained for their stability and longevity.
