Product Overview

The ABB Bailey SPIIT13 Symphony Plus INFI-NET to INFI-NET Local Transfer Module is a communication interface module used to support data exchange between INFI-NET networks within ABB Bailey Symphony Plus automation systems.

The module provides a connection path for transferring process information between local INFI-NET network segments, helping different control nodes share operational data while maintaining the communication structure of the distributed control system.

In large industrial plants, multiple controllers, operator stations, and process monitoring devices often require coordinated communication. The SPIIT13 enables efficient transfer of control and monitoring information between INFI-NET networks, supporting system expansion, network segmentation, and integration of existing ABB Bailey control architectures.

Technical Specifications

Product Features

The ABB Bailey SPIIT13 provides dedicated communication functions for Symphony Plus and INFI-NET based control systems.

Key characteristics include:

• ABB Bailey Symphony Plus communication module
• Supports INFI-NET to INFI-NET data transfer
• Enables communication between network segments
• Designed for distributed control system applications
• Supports integration of ABB Bailey automation nodes
• Suitable for large-scale industrial process systems
• Helps maintain communication continuity between control areas
• Designed for industrial environments requiring stable data exchange

The module allows existing INFI-NET architectures to be expanded while maintaining compatibility with ABB Bailey control platforms.

Working Principle

The SPIIT13 operates as a communication bridge between two INFI-NET network paths.

The basic communication process is:

INFI-NET Network A → SPIIT13 Local Transfer Module → INFI-NET Network B

The module receives communication packets from one INFI-NET network segment, processes the transfer information, and forwards the required data to another connected INFI-NET network.

The transferred information may include:

• Process variables
• Control signals
• Device status information
• Alarm and event data
• Network communication messages

By managing communication between network segments, the SPIIT13 helps maintain coordinated operation across distributed control system architectures.

Role in a Symphony Plus Control System

The ABB Bailey SPIIT13 plays a communication expansion role within Symphony Plus and INFI-NET control architectures.

A typical system structure is:

Operator Station → Symphony Plus Controller → INFI-NET Network → SPIIT13 → Additional INFI-NET Segment

The module allows separate INFI-NET sections to exchange information, which is especially useful in large facilities where control systems are distributed across multiple process areas.

It supports system designs that require:

• Network expansion
• Control area integration
• Existing system modernization
• Communication path extension

Industrial Applications

The ABB Bailey SPIIT13 INFI-NET to INFI-NET Local Transfer Module is commonly applied in industrial process control environments.

The actual application depends on the plant communication architecture and existing ABB Bailey system configuration.

Installation and Maintenance

Proper installation and configuration are important for reliable network communication.

Recommended procedures include:

• Verify compatibility with Symphony Plus and INFI-NET systems
• Confirm network connection configuration
• Check module installation position
• Inspect communication wiring
• Verify network addressing settings
• Monitor communication diagnostics
• Check alarm and status information
• Perform periodic system communication tests

When replacing an SPIIT13 module, engineers should confirm network parameters and restore communication settings before returning the system to operation.
