Industrial Application Scenarios

Oil & Gas Refineries: Deploy in hydrocarbon processing facilities where the INNPM12 manages communication between distributed control units monitoring distillation columns, reactors, and safety instrumented systems. Redundant operation ensures continuous data flow even during module failures, preventing costly production interruptions.

Chemical Manufacturing: Integrate into batch control systems where precise recipe execution demands reliable data exchange between process controllers, analyzers, and actuators. The module's extended temperature rating supports installations in non-climate-controlled equipment rooms adjacent to production areas.

Power Generation Plants: Implement in thermal, combined-cycle, and cogeneration facilities where the INNPM12 coordinates communication between boiler controls, turbine governors, and emissions monitoring systems. Deterministic performance ensures regulatory compliance for real-time emissions reporting.

Pulp & Paper Mills: Utilize in continuous process lines where the module synchronizes data between digester controls, bleaching systems, and paper machine drives. Hot-swap capability enables maintenance during production runs, minimizing downtime impact on 24/7 operations.

System Integration & Architecture

The INNPM12 operates as the central communication hub within INFI 90 control networks, interfacing between high-level supervisory systems and field-level I/O modules. When paired with the INNIS01 Network Interface Module, it forms a redundant communication pair that automatically switches to the backup processor upon primary failure detection—typically within 50 milliseconds.

The module supports multi-drop Cnet topologies spanning up to 2,000 meters with fiber optic extensions, enabling distributed architectures across large industrial campuses. Protocol translation capabilities allow legacy INFI 90 systems to communicate with modern Ethernet-based SCADA platforms without costly infrastructure replacement.

Redundancy & Fault Tolerance

• Automatic Failover: Seamless switchover to backup processor with zero data loss
• Health Monitoring: Continuous self-diagnostics with predictive failure alerts
• Synchronized Operation: Dual processors maintain identical state for bumpless transfer
• Isolated Power Domains: Independent power supplies prevent single-point failures
• Watchdog Timers: Hardware-level fault detection and recovery mechanisms
