PROFIenergy is a Common Application Profile of the Industrial Ethernet protocol PROFINET. It enables the deployment of Energy Management strategies over PROFINET architectures. The PROFINET address schema is used for the PROFIenergy service access point (PESAP) only. Although the PROFIenergy services are defined based on PROFINET mechanisms (e.g. record read/write), a PROFINET independent implementation accessible through a different PESAP is possible. OPC UA provides a service access point independent of PROFINET.
