IEC61850 module
The IEC 61850 module shows information about communication protocols for intelligent electronic devices at electrical substations. These currently supported protocols are:
- GOOSE (Generic Object Oriented Substation Event)
- Sampled Values
The recognized data is transferred as payload of OSI-Layer 2 packets (optionally with VLAN tags). For GOOSE (in Protocol Data Unit - PDU) and Sampled Values (in Application Service Data Unit - ASDU) data units, sequence counters are used to allow reordering the received packets and detecting lost packets.
Overview
Information about all recognized IEC 61850 packets are shown as values and graphs to give a quick overview. Global traffic can be shown in the traffic graph to see the share of each IEC 61850 protocol on the overall traffic.
For each of the protocols, measures of packets and data (accumulated and as per second rate), provide an impression of the used network capacity. Problems in the packet sequence are available as counters for expected packets (according to seen sequence numbers), lost packets (expected sequence number missing), repeated packets (sequence number seen multiple times). A PCAP download button allows capturing that traffic.
Devices
All devices sending or receiving IEC 61850 traffic are shown with their MAC address and the detected protocol. Besides packet counts and data rates of the protocol, quality measures like expected, lost and repeated data units/packets are shown. For having a quick overview, multiple graphs can be shown simultaneously for:
- general IEC 61850 traffic rate
- GOOSE packet rate rate
- Sampled Values data unit rate
The traffic for the specific device and protocol can be captured using the PCAP download button.
A complex filter for the shown row values can be used to limit the shown devices to the specific needs.
Connections
All connections containing IEC 61850 traffic are shown with their two communication partners' MAC address and the detected protocol. Besides packet counts, data rates and time of last detected activity, quality measures like expected, lost and repeated data units/packets are shown. For having a quick overview, multiple graphs can be shown simultaneously for:
- general IEC 61850 traffic rate
- GOOSE packet rate rate
- Sampled Values data unit rate
The traffic for the specific connection and protocol can be captured using the PCAP download button.
A complex filter for the shown row values can be used to limit the shown connections to the specific needs.
