Product Overview

The ABB Bailey NPTM01 Point Table Module is a data management module used in ABB Bailey INFI 90 / Net 90 Distributed Control Systems (DCS). It is responsible for organizing, storing, and managing process “point” information used by the control system.

These “points” represent key process variables such as:

• Process values (PV)
• Setpoints (SP)
• Output values (OP)
• Internal control references

The module plays an important role in ensuring structured data handling within the distributed control architecture.

Technical Specifications

Function Description

The NPTM01 is responsible for organizing process data into structured tables used by the control system.

It performs the following functions:

• Stores process control points
• Organizes system variables into structured formats
• Provides data mapping for controllers
• Supports communication between system modules
• Enables consistent access to process data across the DCS

It does not directly control field devices, but supports the control logic by managing data structures.

Working Principle

The module operates as a data organization layer inside the ABB Bailey system.

1. Process signals are collected from I/O and loop modules
2. Data is formatted into defined point structures
3. The point table stores PV, SP, OP and related values
4. Controller modules access this structured data
5. System logic uses these values for process control execution

This structure ensures consistent and synchronized data handling across the control system.

System Role

Within ABB Bailey DCS architecture, the NPTM01 supports:

• Process data mapping
• System-wide variable organization
• Communication between control modules
• Structured control database management
• Plant loop data coordination
