ABB Relion 670 series - Protocol Reporting Via IEEE 1344 and C37.118 PMUREPORT; Identification

The data streams in the IED can be sent as unicast or as multicast. The user-defined IP
address set in the parameter UDPDestAddress[x] for each UDP stream defines if it is a
Unicast or Multicast. The address range 224.0.0.0 to 239.255.255.255 (Class D IP
addresses) is treated as multicast. Any other IP address outside this range is treated as
unicast and the UDP data will be only sent to that specific unicast IP address. In addition to
UDPDestAddress[x] parameter, UDPDestPort[x] parameter is used to define the UDP
destination port number for UDP client group[x].
In case of multicast IP, it will be the network switches and routers that take care of
replicating the packet to reach multiple receivers. Multicast mechanism uses network
infrastructure efficiently by requiring the IED to send a packet only once, even if it needs
to be delivered to a large number of receivers.
If there are more than one UDP client group defined as multicast, the user shall set
different multicast IP addresses for each UDP group.
The PMU clients receiving the UDP frames can also connect to the IED to request
(command frame) config frame 1, config frame 2, config frame 3, or header frame, and to
disable/enable real time data. This can be done by connecting to the TCP port selected in
TCPportUDPdataCtrl[x] for each UDP group. This connection is done using TCP. The
IED allows 4 concurrent client connections for every TCPportUDPdataCtrl[x] port (for
each UDP client group[x]).
If the client tries to connect on TCPportUDPdataCtrl[x] port using a PMU-ID other than
what is configured for that PMUREPORT instance (PMUReportUDP[x]), then that client
is immediately disconnected and the UDPCtrlCfgErrCnt is incremented in PMU
Diagnostics on LHMI at Main menu/Diagnostics/Communication/PMU diagnostics/
PMUSTATUS:1
Even if the parameter SendDataUDP[x] is set to Disable it is still possible for the clients
to connect on the TCP port and request the configuration frames.
