Description
Product Overview
The INNIS01 is a dedicated network interface slave module used within ABB INFI 90 OPEN and Symphony Harmony distributed control platforms. It serves as a communication gateway that links controller-level modules with plant-wide supervisory networks, enabling coordinated data exchange across large-scale industrial systems.
The module is designed for rack-based installation and operates as a key node within ABB’s distributed control communication architecture.
System Function
This unit provides the communication pathway between:
-
Process control units
-
I/O and interface modules
-
Operator stations and engineering systems
-
Higher-level plant network infrastructure
It ensures synchronized data transfer between field-level control hardware and supervisory-level applications.

Communication Architecture
The INNIS01 operates as a high-speed network node within ABB’s distributed control system structure. It supports multiple communication rates and enables scalable system expansion through loop-based architecture.
Its design allows integration of multiple controller and interface types within a unified network topology, supporting large distributed installations.
System Integration
The module occupies one slot in the INFI 90 OPEN mounting rack and interfaces directly with the system backplane. It acts as a bridge between control hardware and plant-level communication networks without requiring external configuration tools at the module level.
Electrical and Operational Characteristics
Power is supplied through the system backplane, eliminating the need for external wiring. The module is optimized for continuous industrial operation and designed to maintain communication stability under long-duration runtime conditions.
Typical Applications
-
Power plant distributed control networking
-
Chemical process control communication systems
-
Oil and gas facility data integration networks
-
Large-scale manufacturing control architectures
-
Multi-node industrial automation systems
Frequently Asked Questions
