Product Description

The INNIS01 is a high-performance Network Interface Slave (NIS) module for the ABB INFI 90 and Symphony Plus distributed control systems. It serves as the primary hardware gateway between a functional node and the INFI-Net communication loop. By managing low-level network protocols and data buffering, the INNIS01 ensures high-speed, deterministic data transfer, allowing multiple system interfaces to synchronize seamlessly in complex process environments.

Application Scenarios

The INNIS01 is commonly deployed in large-scale DCS architectures, linking Process Control Units (PCUs) and Operator Interface Stations (OIS) to the central plant network. Typical uses include:

  • Paired with NTCL01 termination units for complete network connectivity

  • Thermal power plants and large-scale petrochemical refineries

  • Environments requiring high-speed data transfer and rapid response times

Frequently Asked Questions

Q: Which termination unit is required for this module?
A: The INNIS01 typically interfaces with the NTCL01 Communication Link Termination Unit to complete the physical network connection.

Q: Does this module support both 2 Mbaud and 10 Mbaud rates?
A: Yes. The INNIS01 can operate at either 2 Mbaud or 10 Mbaud, depending on loop requirements and legacy compatibility.
