Complete, Flexible, and Reliable


In today’s world of brilliant machines, operators require high-performance automation solutions that seamlessly connect their machines, data, and people while ensuring the safety and integrity of their process and equipment. This convergence of connectivity and safety is occurring just as a generation of skilled workers is retiring, and risks to infrastructure and processes are increasing. This combination of factors has resulted in more stringent safety regulations and system certification requirements as well as greater scrutiny of program and operator integrity.

To help meet the ever-evolving safety challenges of today’s connected world, GE combines its leadership of the Industrial Internet with its rich history of process safety to deliver the Mark VIeS Functional Safety System.

The Mark VIeS Functional Safety System is born from a decades-long heritage of turbine protection and control. The Mark VIeS system is a cost-effective, complete, flexible, and reliable functional safety system with enhanced cyber security for critical processes such as plant emergency shutdown, burner management, critical process control, and fire and gas detection applications.

The Mark VIeS Functional Safety System is designed to perform in the extreme conditions found in industries such as:

  • Oil & Gas
  • Power Generation
  • Chemical and Process
  • Pulp and Paper
  • Mining and Minerals Engineering



A Proven and Safe Solution

GE brings decades of domain expertise to the Mark VIeS Functional Safety

System. The Mark series of controllers has earned a reputation for superior running reliability and superior tripping reliability when required in thousands of TMR systems installed in power generation and infrastructure applications globally. These proven philosophies are at the heart of the Mark VIeS Functional Safety System.

The Mark VIeS can be applied as a stand-alone safety application or as part of GE plant-wide control solutions. To help protect your infrastructure, the Mark VIeS system’s enhanced cyber security features integrate with GE plant-wide security management systems, providing perimeter defense and intrusion detection and protection against denial of service (DOS) attacks and buffer overrun.

The proven and reliable Mark VIeS system helps keep operations safe and secure through:

  • Branded and locked application code
  • Dedicated security process and response
  • Limited data access
  • Improved passwords
  • Achilles Certification – Level 1
  • User authentication and access control
  • Security logs
  • Hardened protocols

Reliability in Harsh Environments

GE understands that safety systems don’t just reside in clean rooms. That’s why the Mark VIeS Safety Management System provides high performance in the extreme conditions found in many process environments. The processors, network switches, and I/O components are approved for hazardous location, Class 1, Division 2 and the Mark VIeS can operate in temperatures ranging from -30° to -65° C without fans or other external cooling.

Integrate with Existing Control Systems for Better, Faster Decisions

GE understands the importance of seamless integration between your safety and basic process control solutions. The Mark VIeS offers flexibility, scalability, and common configuration and standards-based operational interfaces to integrate with basic process control systems. This allows world-class safety functionality to connect to existing processes, creating a seamless safety program and reducing the installed and operating costs of your control system.

The Mark VIeS enables real-time visualization by sharing data through plant-wide control systems, HMI, data historians, device management systems, and platform-wide trending tools. Key personnel gain access to critical operational information, allowing them to make better, faster decisions.

Enhanced Productivity and Performance

Sophisticated application automation tools and seamless data integration between the control system and HMI enable process efficiencies during project execution to reduce delivered cost and improve quality. Enhanced software reusability features allow users to create and maintain logic standards that can then be efficiently deployed over and over again. This reduces project costs, increases integrity of software, and reduces risk of human error. All critical considerations when deploying safety related systems.
