Functional safety
Services

El término Seguridad Funcional se refiere a la parte de la seguridad global de un sistema consistente en que sus componentes o subsistemas eléctricos, electrónicos y programables con implicaciones en materia de seguridad respondan de forma adecuada ante cualquier estímulo externo, incluyendo errores humanos, fallos de hardware o cambios en su entorno.

Con la complejidad de los sistemas electrónicos aumenta también el número de posibles errores. Por ello, la serie de normas IEC 61508 establece el uso de diversos métodos para evitar errores sistemáticos (de especificación, implementación, etc.) y para la recuperación segura ante averías y fallos de funcionamiento (a menudo debidos a fenómenos físicos o un manejo inadecuado). El objetivo último es minimizar el riesgo de lesiones.

Nuestra gran experiencia nos permite ofrecer nuestros servicios como expertos en seguridad funcional.

Safey Intregity Level (SIL)

The Safety Integrity Level (SIL) is defined as the relative level of risk reduction that a safety function provides, or as the specified target level of risk reduction of that function.

We provide cosultation, adaption and studies of new processes while meeting the requirements of the following standards:

IEC 61508, “Functional Safety of electrical, electronic and electronic programmable control systems. (E/E/EP).”

IEC 61511, “Functional Safety: Safety instrumented systems for the industrial processing sector”.

Safety Instrumented Systems (SIS)

Safety Instrumented Systems (SIS)

Safety Instrumented Systems (SIS) also known as “Interlocks”, are utilized in hazardous processes for protection and to reduce the risk of accidents.

The implementation of SIS, drives the plant in safe condition.

SIS consist of three essential elements: Sensors systems, Controllers and Actuator systems:

The implementation of SIS, drives the plant in safe condition.

SIS consist of three essential elements: Sensors systems, Controllers and Actuator systems:

These elements form an SIS chain and are valued in terms of their functional safety.

To achieve this, a very complex and exhaustive process is defined in standards IEC 61508 and IEC 61511.

The SIS must assess and analyse both the hardware and the software using several techniques,  such as:

  • Fault Analysis(FMEA).
  • Fault Tree.
  • And others.
