ABB SPIET800 Ethernet CIU Transfer Module INFI-NET to TCP/IP Gateway

Product Description

The SPIET800 (SPIET800) is a high-performance Ethernet Communication Interface Unit (CIU) developed by ABB to serve as a critical bridge between legacy INFI-NET control networks and modern TCP/IP-based infrastructures. This module functions as a sophisticated protocol gateway, enabling seamless bi-directional data exchange between INFI 90 or Network 90 controllers and contemporary host computers, SCADA platforms, or industrial historians.

Designed for maximum data integrity, the SPIET800 (SPIET800) is more than a simple pass-through converter. It features an active buffering system that localizes process values, alarm states, and diagnostic information from the INFI-NET bus. By managing data prioritization and local storage, the module ensures that critical control information is successfully delivered to host applications via standard socket connections, effectively mitigating the risk of data loss during transient network congestion or communication interruptions.
