ABB introduced MMS support for AFS series Ethernet switches
The number of Ethernet switches with integrated IEC 61850-8-1 server increases. Manufacturers do not only implement standard logical node classes according to IEC 61850-7-4 but also those ones introduced by IEC 61850-90-4 technical report. These switches do also support buffered and unbuffered reporting mechanisms. Seems like the closest future is the one where IEC 61850-8-1 (MMS) communications will replace communications over SNMP (being widely used at the moment). This will allow for integration of Ethernet switches in process control systems the same way as it is done with IEC 61850-8-1 pr
