vIED, the CIGRE Way: What WG B5.84 Says You Can — and Cannot — Virtualise

CIGRE's first dedicated framework for virtualised IEDs will not publish until Q1 2028 — but the vPAC pilots that have to align to it are being commissioned now. Its scope is already public, through the working group's Terms of Reference and a framework article refeatured in ELECTRA 345 (April 2026): what is mandatory, what is deliberately out of scope, and what every 2026 vPAC pilot should already be doing in response.

FITNESS Pilot: Are You Fit For The Future?

Future Intelligent Transmission Network SubStation (FITNESS) is the pilot live multi-vendor digital substation demonstration in GB. The project was successfully awarded under RIIO NIC, Ofgem, in late 2015 and detailed design work began in 2016.

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

Heartbleed Bug Found in ABB Relays

Much-talked-of Heartbleed bug of open-source OpenSSL cryptography library has been found in ABB Relion 650 series IEDs. Care about this if your IED firmware revision is 1.3.0. Word has been spread by ICS-CERT (Industrial Control Systems Cyber Emergency Response Team).
