Historian se comercializa con diferentes versiones (principalmente "Essentials", "Standard" o "Enterprise"), cada una de ellas con un conjunto de funcionalidades determinado.
- "Essentials" es la versión que se distribuye gratuitamente con los SCADA de GE Digital. Es una versión relativamente limitada pero suficiente para un uso básico de Historian en muchas aplicaciones SCADA de pequeño o medio tamaño
- "Standard" es una versión de pago y completa (sin las limitaciones de "Essentials". Puede hacerse cargo de la mayoría de necesidades en sistemas de hasta 50.000 variables a historizar
- "Enterprise" es la versión más completa, con licencias de hasta 20.000.000 variables. Imprescindible en grandes nubes corporativas que tengan que concentrar la información de múltiples servidores SCADA
Las versiones "Standard" y "Enterprise" se suministran, sin cargo adicional, con una versión "Essentials" de Operations Hub, el portal web de GE Digital que, entre otras cosas, permite acceder a los datos guardados en Historian para analizarlos, graficarlos, etc.
