Sigmafine Extensions

Extend Sigmafine or the OSIsoft PI System with industry and domain specific calculation capabilities

Although the base Sigmafine system embeds multiple analysis rules suitable for a wide range of industries and applications, some uses cases require industry or applicaiton specific analysis and calculations.  Sigmafine Extensions is how Pimsoft integrates such requirements.

In the rare cases when industry or application specific analyses are not supported by Sigmafine natively, Pimsoft offers customer a custom extension development and support service. Contact us for more details.
