ABB INIET800

Product Brief:​ The INIET800 is a gateway / interface module (or sometimes a software/hardware bridge kit) that enables data exchange between a legacy ABB INFI 92 / Harmony system (via its Infi-Net/ Nodbus​ network — INNIS21/INICT13 interface) and a newer ABB IET800 / Symphony Plus​ node or Plant Network. It allows gradual migration — INFI 90 I/O and controllers can continue operating while selected process data, alarms, and commands are passed to/from the Symphony Plus / 800xA environment. In some references “INIET800” denotes the Infi-Net to IET800 communication interface card​ that plugs into a Symphony Plus node.

Description

ABB INIET800

  • Technical Specifications (typical gateway function):
    • Legacy Side Interface: Infi-Net (INNIS21 / INICT13 compatible Nodbus peer) — connects as a “pseudo-INFI 90 node” on the Infi-Net ring/token-bus
    • Modern Side Interface: Ethernet 10/100/1000 Mbps — connects to Plant LAN / Symphony Plus node (IET800, AC 800M with CI854, or 800xA Connectivity Server)
    • Protocols Supported: INFI 90 Nodbus (peer-to-peer data exchange, block read/write), OPC DA/HDA/Alarms & Events (on modern side), optionally Modbus TCP for third-party
    • Data Mapping: Up to N analog and digital points (system-dependent — typically 2000+ tags) mapped bidirectionally
    • Time Synchronization: Passes NTP from modern system to legacy nodes or vice-versa
    • Power: 24 V DC (from IET800 node or separate PSU)
    • Indicators: Power, Infi-Net Link, Ethernet Link, Error LEDs
    • Operating Temp.: 0 °C to +55 °C
    • Mounting: DIN rail or in IET800 node slot / separate gateway enclosure
  • Functional Features:
    • Transparent tag mapping — legacy INFI 92 block addresses mapped to OPC Item IDs or 800xA aspects
    • Alarm forwarding — INFI 90 alarms appear in Symphony Plus / 800xA alarm list
    • Supports redundant Infi-Net A/B rings
    • Allows phased migration — keep legacy I/O racks alive while new operator stations are Symphony Plus / 800xA
  • Application Scenarios:
    • Brownfield modernization — plant originally INFI 92 / Harmony wants new 800xA or Symphony Plus operator interface while retaining existing I/O and controllers
    • Data concentration — bring selected legacy INFI 92 process data into corporate MES / PI historian via OPC
    • Coexistence period during multi-year retrofit
  • Material & Structure / Working Principle / Installation / Precautions:
    • Install INIET800 gateway node on Plant LAN; connect Infi-Net cable to INNIS21-compatible port (often via A/B coax or twisted-pair Infi-Net cable with proper termination)
    • Configure in INFI 92 Engineering Workbench — add INIET800 as a node on Infi-Net with node address; define exported blocks (analog/digital) in INFI 92 database
    • Configure in 800xA / Symphony Plus — import OPC server; browse INFI 92 tags; build aspects
    • Verify Infi-Net ring termination and node address uniqueness
    • Precaution:​ Changing INFI 92 database (adding/removing exported blocks) requires download — coordinate with operations to avoid unintended controller restart. Ensure Infi-Net node address does NOT conflict with existing INFI 92 nodes. Maintain Infi-Net terminators at both ends of the ring.
