Alarm Logic Engine

The Alarm Logic Engine is the computational component of an Alarm Management System responsible for analyzing input signals, sensor data, and system states against configured logic rules. It determines when alarm conditions are met, prioritizes alarms, suppresses nuisance alarms, and initiates appropriate notification and control actions to ensure safe and efficient industrial operations. This engine is designed for integration into machinery and equipment manufacturing environments, where it functions as a part-level component within a larger alarm management framework. It continuously monitors input parameters from sensors and control systems, comparing them against threshold values and logical conditions defined in its rule base. When conditions match alarm criteria, it executes programmed logic (AND/OR gates, timers, sequences) to validate the alarm, apply filtering to prevent false positives, assign priority levels, and trigger output actions such as visual/audible alerts, operator notifications, or automated shutdown sequences. The engine supports a configurable number of alarm inputs (8–64 channels), with scan cycle times ranging from 10 to 100 ms, and a logic resolution of 16 bits. It operates within a temperature range of -40 to 85 °C (storage: -40 to 105 °C) and relative humidity of 5–95% non-condensing, per IEC 60068-2-1/2 and IEC 60068-2-78. Supply voltage is 24 V DC ±10% (IEC 61131-2), with power consumption between 5 and 15 W depending on input count. Ingress protection ranges from IP20 to IP65 (IEC 60529). Alarm response time is 50–200 ms, and logic capacity is 1000–10000 programmable rules. Communication protocols include Modbus TCP, Profinet, and EtherNet/IP (IEC 61784). Physical specifications include weight of 0.5–2.0 kg and dimensions from 100x75x60 mm to 200x150x120 mm. These values are directory reference ranges; verify model-specific data with the manufacturer.
