ABB INIIT13 Infi‑Net Network Transfer Module

The ABB INIIT13 is an Infi‑Net to Infi‑Net network transfer module for ABB Bailey INFI‑90 / Symphony DCS distributed control systems. It realizes interconnection between two independent Infi‑Net token‑ring networks, completes cross‑network data forwarding and message transmission among controllers, workstations and control nodes. It acts as the core network bridge for large‑scale multi‑domain DCS architecture.

This rack‑mount plug‑in module supports high‑speed token‑ring data processing, equipped with hardware self‑diagnosis and LED status indicators. It supports hot‑swap operation and can cooperate with redundant network configuration to improve system reliability. Widely used as aftermarket spare hardware for power, petrochemical and chemical industries for legacy DCS system maintenance, network expansion and technical retrofitting projects.

FAQ

1. Q: Can INIIT13 work without INFI‑90 backplane and Infi‑Net ring network?
   A: It must be inserted into INFI‑90 rack and connected with two Infi‑Net token‑ring networks, cannot complete cross‑network forwarding as standalone hardware.
2. Q: What are typical module failure symptoms?
   A: Cross‑ring‑network data transmission interruption, partial nodes cannot access devices on another ring, network link alarm, loss of cross‑domain alarm and process data.

3. Q: How to complete commissioning and diagnosis?
   A: Check 24VDC power supply and Infi‑Net ring cable connection; configure network domain parameters via DCS configuration software, observe LED status and read module diagnostic logs.
