ABB INICT01 Computer Transfer Module

‑ Power Supply：15 VDC from PCU card rack backplane；typical power consumption 7.2 W

‑ Mechanical Structure：standard INFI‑90 PCU slot plug‑in module；front‑panel handle locking structure；weight approx 0.85 kg

‑ On‑board Resources：INFI‑NET bus interface unit, computer communication driving circuit, data buffer memory, module self‑diagnosis circuit

‑ Communication Interface：INFI‑NET high‑speed serial loop interface；computer side ICI communication interface

‑ Galvanic Isolation：galvanic isolation between INFI‑NET network side and computer communication side, isolation rating 2500 VAC

‑ Core Function：protocol conversion, data buffering, bidirectional data transmission between INFI‑NET loop and external computer

‑ Protection：bus surge‑suppression, communication signal over‑range monitoring

‑ Status LED Indicators：Power indicator, Module Fault indicator, network communication status LED, computer link status LED

‑ Weight：approx 0.85 kg

‑ Connects to INFI‑NET control loop via cooperating with INNIS01 module, receives process data, alarm information and controller parameters from DCS network, forwards to external host computer.

‑ Transmits upper‑level computer issuing commands, set‑point values and configuration download data to INFI‑NET DCS control nodes.

‑ Implements data buffer processing, reduces communication conflict of high‑speed loop, guarantees stable data interaction between computer and DCS system.

‑ Module self‑diagnosis monitors back‑plane power supply, INFI‑NET bus link, computer communication channel and on‑board hardware status; detects signal loss, communication interruption and hardware fault, reports fault status to DCS system.

‑ Cannot run independently; must be matched with INNIS01 network interface slave module and INFI‑90 PCU rack. INICT01 belongs to legacy DCS hardware, only compatible with INFI‑90 / Symphony‑Harmony system, cannot be used for other series DCS.

‑ Continuously monitors back‑plane power, INFI‑NET bus communication, computer link and internal hardware health. Detected faults activate fault LED and report fault word to DCS controller.

‑ No local historical‑data storage; module status and fault codes are read through DCS system or commissioning tool.

‑ Module hardware failure will cause loss of communication channel between INFI‑NET loop and external computer; DCS internal control loop still runs normally, but upper‑computer cannot exchange data with DCS via this channel.

‑ Back‑plane connector: inserts into INFI‑90 PCU rack slot, connects to INNIS01 module through rack internal bus.

‑ Computer communication interface: connects to external host computer equipment.

‑ Mounting：insert into standard INFI‑90 PCU card rack slot

‑ Operating Temperature：‑10 ℃ ~ +60 ℃

‑ Storage Temperature：‑40 ℃ ~ +70 ℃

‑ Relative Humidity：5‑95 %RH, non‑condensing

‑ Protection Class：IP20, for cabinet‑internal installation.

‑ Power off PCU rack before inserting or removing this module. Ensure matching with INNIS01 module, incorrect module collocation will lead to communication failure.

‑ For spare‑part replacement: verify model INICT01; after installation, check back‑plane power supply, INFI‑NET‑loop communication and computer‑host data interaction function. Hardware version mismatch will cause communication abnormality.

‑ Module fault results in failure of data exchange between DCS INFI‑‑NET loop and external computer.
