IIoT decision making with process and energy control architectures

Energy and Process control systems were once conveniently separated. Tighter integration is now required because of more widespread use of higher efficiency motors and variable frequency drives as well as faster dynamic load management schemes for plants with a minimal spinning reserve capability. Digital age IIoT interactions between the ANSI/ISA95 and IEC61850 Bus Architectures present challenges for security, data flow, equipment life-cycle, translation and decision making. The paper reviews how these newer technologies and design drivers can be arranged to provide better quality decision making at the operational level. In addition the various challenges of exposing high availability critical plant subsystems to the various components of an IIoT based architecture for better analytic and machine learning purposes are explored.
