Extensions for IEC 61850 System Configuration Language to describe HMIs have been proposed
IEC TC 57 has published (57/1767/NP) a proposal for extending the System Configuration Language (SCL) to provide high-level direction in terms of how best to bind the HMI graphical objects with the IEC 61850 data objects/attributes using the configuration description language defined in IEC 61850-6. The concept willl be based upon the existing System Configuration Language (SCL) defined in IEC 61850-6, in addition to possibly incorporating other non-IEC namespaces such as the W3C's Scalable Vector Graphics (SVG) namespace.
