Function and Working Principle
The IMCOM03 operates as a standalone enhanced controller within the ABB Bailey architecture.
Its main functions include:
- Executing control logic for industrial processes
- Processing analog and digital input signals
- Generating control outputs for field devices
- Managing closed-loop control strategies (e.g., PID loops)
- Communicating with other system modules via the DCS network
- Coordinating process control between distributed I/O systems
It serves as a direct process control engine within the INFI 90 system.
Role in Industrial Control Systems
Within ABB Bailey systems, the IMCOM03 functions as a core control execution module.
Typical responsibilities include:
- Local and distributed loop control
- Process variable regulation
- Field device control (valves, pumps, actuators)
- Real-time control logic execution
- Coordination with other controller modules
It is one of the key “decision-making” elements in the control system.
Industrial Applications
The ABB IMCOM03 is widely used in:
- Power generation plants
- Oil and gas facilities
- Petrochemical industries
- Refining processes
- Chemical production plants
- Water treatment systems
- Heavy industrial automation systems
- Legacy ABB Bailey INFI 90 / Network 90 installations
Installation and System Integration
For stable operation:
- Install in compatible ABB INFI 90 rack systems
- Ensure correct module addressing and configuration
- Maintain proper grounding and shielding
- Use separated wiring for analog and power signals
- Verify control logic configuration during commissioning
