Cisco, the biggest supplier of networking equipment in the world, has managed to ship servers for seven entire weeks without noticing that they had a different default password for the admin account.
GOOSE-messaging has been covered a lot in many technical papers and to add anything valuable to the subject is rather difficult. But we will try. And functional constrained data will help us with that.
XML Marker - an alternative to simple text editing tools for overview of SCL files.
There are several applications that can be used for monitoring IEC 61850 traffic in the Ethernet network. But there is one free-of-charge option everyone should know about.
Abstract for the patent Merging unit and method of operating a merging unit states the following: A merging unit including at least one input interface for receiving input data characterizing at least one voltage and/or current related to a component of a...
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
When configuring GOOSE and Sampled Values communications it is useful (and sometimes is a must) to have the possibility to check VLAN and Priority tags. Whether your network adapter driver strips tagging or not will define the availability of these parameters not only while using Wireshark, but also other specific tools for analysis of GOOSE and Sampled Values traffic (Omicron SVScout, Omicron IEDScout, GOOSE Inspector, etc.). Today we will see how to make Intel network adapters not to strip this important info.
Updated test register includes a lot more IEC 61850-9-2LE conformant stand-alone merging units and IEC 61850-8-1 ed. 2.0 conformant devices.
In Electric Power Networks of Russia-2014 exhibition MOXA presented DA-820 industrial computer which supports PRP and HSR redundancy protocols. Now process control systems manufacturers and suppliers can use this platform to offer workstations for integration in IEC 61850 station bus networks without redundancy boxes.
Siemens presented the new series of arc-fault protection devices 7XG31. The new series includes 7XG3124 RA24 device which is capable of transmitting GOOSE messages on detection of arc-faults in different compartments of enclosed switchgear. It is possible to...
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).
CIGRE Study Committee B3 will include a new working group - Impact of NCIT applications on HV Gas Insulated Switchgear (WG# B3.39). This subject has not yet been covered by any of CIGRE activities.
