TheABB IMCKN01is a specialized Clock Network Module within the Infi 90 and Symphony Harmony distributed control system (DCS) family. Its primary role is to provide a highly accurate time base for the entire control network, ensuring that all distributed modules, process control units, and operator consoles are synchronized to the same millisecond.
Specifications
Model Designation:IMCKN01
Function:Master Clock / Network Time Synchronization
Power Consumption:Approximately 5.5 Watts (nominal)
Time Accuracy:High-precision crystal oscillator for millisecond-level synchronization
Network Interface:Connects directly to the Plant Loop or INFI-NET communication systems
Operating Temperature:0 to 55 degrees Celsius
Storage Temperature:-40 to 85 degrees Celsius
Mounting:Occupies a single slot in a standard Infi 90 Module Mounting Unit (MMU)
Features
Global Time Synchronization:Establishes a uniform time reference across all nodes in the DCS for consistent data logging.
Redundant Operation:Supports primary and backup clock configurations to prevent system-wide timing loss during hardware failure.
External Clock Support:Capable of syncing with external time sources, such as GPS receivers, for absolute real-world time correlation.
Status Indicators:Equipped with front-panel LED indicators for immediate visual feedback on clock status and network health.
Sequence of Events (SOE) Precision:Enables high-resolution timestamping of alarms and process changes for accurate post-trip analysis.
Seamless Integration:Fully compatible with both legacy Infi 90 hardware and modern Symphony Plus control environments.
