Core Functions

This product is an industrial-grade OPC Alarms & Events Server by HIMA, Version 4.0.5 (Build239), designed specifically for HIMA safety control systems.

It is primarily responsible for the standardized transmission and exchange of alarm and event data between HIMA safety systems and third-party OPC‑compatible clients, establishing a reliable communication bridge between field‑level safety controllers and upper‑level monitoring systems.

The server fully complies with the OPC A&E specification, supporting event subscription and alarm filtering by area, source, category, and severity.

It includes functions for alarm acknowledgment, return‑to‑normal processing, and high‑precision timestamping.

It can map HIMA controller signals to meaningful event categories and conditions, organize signal sources hierarchically, and adapt to on‑site standards and workflow requirements.

Built‑in secure communication mechanisms support hierarchical permission management to effectively prevent unauthorized access.

Logging and diagnostic functions record communication status, alarms, events, and operations in real time, supporting fault tracing and system maintenance.

This version improves DCOM communication stability, fixes connection issues in earlier releases, and enhances smooth operation under high load.

It integrates seamlessly with HIMA safety control systems and enables fast deployment without additional drivers, ensuring real-time and accurate transmission of alarm and event data in industrial safety systems.

Application Scenarios

Widely used in high‑safety‑critical industrial sectors including petrochemical, power, metallurgy, rail transit, and pharmaceuticals.

Compatible with the full range of HIMA safety controllers, it connects third‑party OPC‑compatible clients such as SCADA/HMI platforms, DCS systems, historians, and alarm management tools.

Especially suitable for safety‑related applications requiring centralized alarm monitoring, improved situational awareness, and simplified lifecycle management of events across units and sites, such as emergency shutdown systems, safety instrumented systems (SIS), and critical equipment monitoring loops.

It can be deployed on servers within industrial control networks to enable centralized collection and standardized distribution of alarm and event data from HIMA safety systems.

This helps system integrators and operators achieve consistent, interoperable alarm management, ensures production safety and stable system operation, and performs reliably in harsh 24/7 industrial environments.

III. Installation and Maintenance Guide

Pre‑installation Requirements

Environment: Install the server in a dust‑free, non‑condensing, well‑ventilated equipment room, away from strong interference sources such as inverters and high‑voltage cables. Maintain room temperature between 0℃ and +40℃ and humidity 5%–95% non‑condensing. Ensure stable power supply; UPS is recommended to avoid software corruption or configuration loss due to sudden power failure.
System Preparation: Before installation, verify that a compatible Windows Server operating system (Windows Server 2016 or later recommended) is installed. Disable unnecessary firewall port restrictions and open RPC ports (default 135 and dynamic port range). Pre‑install Microsoft Visual C++ 2015–2022 Redistributable to ensure proper functioning of .NET Framework components. Verify network connectivity to HIMA controllers and third‑party clients.
Installation Procedure: Run the installer (Setup.exe), follow the wizard, accept the license agreement, and select an installation path (default path recommended; avoid Chinese characters). The installer automatically checks dependencies and installs missing components. Restart the server after installation and confirm normal startup without errors. For upgrades or configuration migration, select Keep existing configuration or Import legacy configuration to prevent data loss.
Parameter Configuration: After launching the software, configure connection parameters for HIMA controllers (IP address, port, communication protocol) and test communication. Set access permissions for OPC clients and configure user roles. Map controller signals to alarm categories, and define filtering rules, timestamp format, and log storage path. Test alarm and event transmission to confirm stable, low‑latency performance.

Routine Inspection

Operation Status: Check that the software runs without errors or unexpected exits. Verify communication status via the interface to ensure stable connections with HIMA controllers and clients.
Log Review: Regularly inspect system and application logs to identify alarms, communication errors, and permission anomalies. Ensure proper log storage and archive or delete outdated logs to prevent excessive disk usage.
Network and Environment: Check Ethernet connections for loose cables or unstable links. Monitor room temperature and humidity. Verify UPS status to ensure failover during power interruptions.
Parameter Verification: Confirm software version (Version 4.0.5 Build239). Check connection settings, permissions, and alarm mappings for unauthorized changes. Test alarm transmission, filtering, and acknowledgment functions.

Periodic Maintenance

Monthly: Clean temporary files and outdated logs to optimize server performance. Verify software operation and communication stability. Back up configuration files to secure storage.
Quarterly: Check server hardware utilization (CPU, RAM, disk). Install OS updates and dependency patches to improve security. Test access control and review alarm mappings for on‑site adjustments.
Semi‑annually: Perform full backup of configurations and logs. Verify software integrity and repair potential runtime issues. Review DCOM configuration and open communication ports. Evaluate version compatibility and apply official updates only after testing in a non‑production environment. Perform a full server restart to free system resources.
