Alarm Event Log Component – Machinery and Equipment Manufacturing

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
