Component Specifications

Definition
The Alarm Event Log is a critical software component within industrial alarm databases that systematically records timestamped alarm occurrences, including alarm type, severity, source, status changes (activation/acknowledgment/clearance), and associated operator actions. It serves as an audit trail for equipment performance analysis, maintenance scheduling, and regulatory compliance in manufacturing environments.
Working Principle
Operates through real-time monitoring of machine sensor inputs and control signals. When predefined alarm thresholds are breached, the system automatically generates a log entry with metadata. Data is stored in structured databases (often SQL-based) with timestamp precision, enabling chronological retrieval, filtering by parameters, and integration with SCADA/HMI systems for visualization.
Materials
Software-based component; no physical materials. Requires storage media (SSD/HDD) and runs on industrial PCs or embedded controllers with compatible operating systems (Windows IoT, Linux RT).
Technical Parameters
  • Data Retention 30 days to 5 years (configurable)
  • Export Formats CSV, XML, PDF
  • Storage Capacity Configurable, typically 10,000-1,000,000 events
  • Concurrent Alarms Supports 100-500 simultaneous alarms
  • Interface Protocols OPC UA, Modbus TCP, Ethernet/IP
  • Timestamp Resolution Millisecond precision
Standards
ISO 13849-1, IEC 61131-3, ISA-18.2
