Mark VIeS Security System

Online testing and change monitoring: All modifications to the application can be tested and recorded through the software's built-in validation tools;

Diagnosis and Alarm: Real time display of detailed diagnostic information for controllers, networks, I/O, and power distribution units. Even if communication is interrupted, diagnostic data will be retained locally in the controller and will not be lost.

4.2 exSILentia Safety Lifecycle Management

ExSILentia is a professional SIL calculation and management tool developed by Exida company. The functional safety parameters of Mark VIeS components have been pre embedded in the logical solver database of the tool. When designing SIF, users can fully evaluate:

Sensors (such as pressure and temperature transmitters);

Logic solver (Mark VIeS controller and I/O);

Final components (such as shut-off valves, contactors).

The software automatically calculates key indicators such as average requirement failure probability (PFDavg), critical failure frequency per hour (PFH), hardware fault tolerance (HFT), and system capability (SC) to ensure SIL level compliance. This automated workflow significantly improves consistency and design efficiency, reducing the risk of human computational errors.

Network Security: A Defense System Designed for the Connected World

As industrial control systems evolve towards open networks, security systems themselves have become potential targets of attack. Mark VIeS incorporates multi-layer network security protection mechanisms from the beginning of its design and has obtained Achilles Level 1 certification, verifying its network robustness.

The main safety measures include:

Brand and lock application code: prevent unauthorized modifications;

Specialized security processes and responses: covering vulnerability management and patch release;

Minimum data access principle: role-based permission control;

Strengthen password strategy: support complex passwords and regular replacement;

User authentication and access control: integrated Windows domain or local account management;

Security log: Record all login, configuration changes, and alarm events;

Black Channel Communication: Overlaying security layers on standard Ethernet protocols to achieve large-scale secure communication across multiple security controllers without reducing SIL levels.

In addition, the system supports a trusted host table and only allows authorized computers to connect to the controller; The 'controller lock' mode can prevent unexpected modifications during operation; The application branding feature ensures that only digitally signed code can be downloaded and executed.

High availability features: HART, SOE, and advanced diagnostics

6.1 HART Smart Instrument Support

The Mark VIeS I/O module supports the HART protocol and can simultaneously obtain process variables, instrument status, diagnostic information, calibration data, and more. Users can integrate smart meter data into asset management systems without the need for additional hardware, enabling predictive maintenance and performance monitoring.

6.2 Integrated 1ms SOE

Traditional SOE systems require dedicated timing modules and expensive time synchronization servers. The Mark VIeS has built-in high-precision timestamp function in all discrete input and output channels, and users only need to check it in the configuration to enable 1ms SOE. The captured events can be combined and replayed through real-time or historical trend analysis tools to quickly locate the cause of process disturbances and accelerate production recovery.

6.3 Advanced Diagnosis and Alarm

The system continuously monitors the integrity of each safety loop, including:

Channel open/short circuit detection;

The signal exceeds the range;

Inconsistent redundant paths;

Power and grounding faults;

Controller health status (CPU load, memory, temperature).

All alarm and diagnostic information is time stamped and stored in the non-volatile memory of the controller, ensuring that critical evidence is not lost even if communication with the upper computer is interrupted.

Adaptability to harsh environments

GE Vernova deeply understands that security systems are not always installed in clean central control rooms. The entire range of Mark VIeS components (processors, switches, I/O modules) have passed the following certifications:

Class 1, Division 2: Suitable for hazardous areas with combustible gases or vapors (similar to Zone 2);

G3 anti-corrosion grade: meets ISA standards and can withstand corrosive gas environments such as high concentrations of hydrogen sulfide and sulfur dioxide.

Combining a wide temperature range (-40 ° C to+70 ° C, depending on the component) and anti vibration design, this system can be deployed on offshore platforms, desert oil fields, polar LNG receiving stations, and high dust mining environments.
