ABB INIET800 Ethernet Gateway Communication Module
INIET800 is a dedicated Ethernet gateway communication module for ABB Symphony Harmony INFI-90 DCS system. It belongs to the Bailey series hardware and is installed in the DCS standard rack as a communication bridge card between the private INFI-NET control loop and the standard Ethernet TCP/IP network.

Product function
1. Protocol Conversion Gateway: Implement mutual conversion between INFI-NET private bus and Ethernet TCP/IP protocol, and connect the data path between DCS control network and enterprise Ethernet.
2. Cross system data exchange: Forward DCS internal measurement point data to upper level business systems such as upper computer, OPC server, SCADA, HMI, MES, etc., and receive instructions issued by the upper level to be transmitted to the DCS controller.
3. System Transformation Migration : While retaining the original INFI-90 controller and IO cards, expand Ethernet communication capabilities to achieve smooth upgrades of old systems, reduce project costs and downtime risks.
4. Network Redundant Communication : Dual Ethernet ports support network redundant deployment, ensuring uninterrupted communication links in critical process scenarios, and supporting remote web-based configuration and fault diagnosis and maintenance.
