ABB IMCIS02 Communication Interface Module – Reliable serial connectivity for ABB Bailey INFI 90 systems

The ABB IMCIS02 is a communication interface module used in ABB Bailey INFI 90/Harmony systems to bridge controllers with serial devices on the plant floor. From my experience, it’s typically chosen when you need stable RS‑style links to third‑party instruments—think power meters, analyzers, legacy PLCs, or VSDs—without overcomplicating the control strategy. You might notice that it slots right into the standard INFI 90 rack and behaves like any other ABB plug‑in card: predictable, serviceable, and easy to replace during planned outages.

One thing I appreciate is how the IMCIS02 helps extend the life of installed assets. In many cases, plants use it to bring long‑running serial devices into the DCS, while keeping the main controller light on overhead. A maintenance lead at a combined‑cycle plant told us their IMCIS02 “just runs,” which seems to be the typical feedback when serial integration is done right.

Order Placement Process and Guarantees

Key Features

• Serial device integration – Designed for linking INFI 90 controllers with serial field equipment, typically via RS‑style interfaces for dependable data exchange.
• Stable DCS backplane operation – Plug‑in module powered and managed by the INFI 90 backplane, minimizing external wiring complexity.
• Deterministic behavior – Suits power, petrochemical, and pulp & paper sites where predictable serial polling is preferred over ad‑hoc gateways.
• Service-friendly form factor – Front‑accessible faceplate with status indicators makes diagnostics and replacement straightforward during maintenance windows.
• Legacy compatibility – In many cases used to connect older instruments (e.g., analyzers, drives) that still perform well but speak only serial protocols.

Technical Specifications

Related or Supporting Products

• ABB IMMFP12 – Multifunction Processor module; often the main controller that supervises I/O and communication modules like IMCIS02.
• ABB INICT13A – Network Interface module for INFI‑NET; used when you need plant‑wide networking in addition to serial links.
• ABB IMASI23 – Analog input module; pairs with IMCIS02 when you combine serial instrument data with hardwired analogs.
• ABB IMDSI14 / IMDSO14 – Digital input/output modules; good for mixed systems where some devices are serial and others are discrete wired.
• Protocol gateways (3rd‑party) – If you need Ethernet protocols in parallel (e.g., Modbus TCP), a gateway can complement IMCIS02’s serial channels rather than replace them.

Installation & Maintenance

• Cabinet & environment – Install in a clean, dry control cabinet meeting typical IEC/UL panel standards. Maintain 0–60 °C ambient and avoid vibration where possible.
• Rack & wiring – Seat the module firmly in the INFI 90 rack; use shielded serial cables with proper drain‑wire grounding. Keep power and serial runs separated to reduce noise pickup.
• ESD & safety – Handle with ESD protection. De‑energize the rack or follow hot‑swap procedures as per site policy before removal/installation.
• Configuration – Parameters are set via the plant’s engineering tool (e.g., the ABB configuration environment used for your INFI 90 system). Verify baud rate, parity, stop bits, and polling timing during commissioning.
• Routine maintenance – Inspect connectors annually, clean faceplate and vents with dry air, and back up configuration files. Firmware updates, when applicable, should follow ABB’s release notes and site change‑management rules.
• Troubleshooting tip – If comms seem intermittent, check commons/grounds first and confirm that the serial cable pinout matches the device’s DCE/DTE expectation.
