sent out to that client. In this figure, X and Y are referring to the user-defined PMU ID Codes for
PMUREPORT instances 1 or 2, respectively. It is up to the TCP client to decide which PMUREPORT
function block shall communicate with that client. Upon successful reception of the first command
by the IED, the PMU ID will be extracted out of the command; if there is a PMUREPORT instance
configured in the IED with matching PMU ID, then the client connection over TCP with the IED will
be established and further communication will take place. Otherwise, the connection will be
terminated and the

At any given point of time maximum of 8 TCP clients can be connected to the IED for IEEE1344/
C37.118 protocol. If there is an attempt made by the 9th client, the connection to the new client will
be terminated without influencing the connection of the other clients already connected. A list of
active clients can be seen on the Local HMI in the diagnostics menu under Main menu/
Diagnostics/Communication/PMU diagnostics/PMUSTATUS:1
6.1.3.2 Short guidance for use of UDP
The IED supports maximum of 6 concurrent UDP streams. They can be individually configured to
send IEEE1344 or C37.118 data frames as unicast / multicast. Note that [x] at the end of each
parameter is referring to the UDP stream number (UDP client group) and is a number between 1
and 6. Each of the 6 UDP groups in the IED has the following settings:
SendDataUDP[x] – Enable / disable UDP data stream
1.
ProtocolOnUDP[x] – Send IEEE1344 or C37.118 on UDP
2.
PMUReportUDP[x] – Instance number of PMUREPORT function block that must send data on

this UDP stream (UDP client group[x])
UDPDestAddres[x] – UDP destination address for UDP client group[x] (unicast / multicast
4.
address range)
UDPDestPort[x] – UDP destination port number for UDP client group[x]
5.
TCPportUDPdataCtrl[x] – TCP port to control of data sent over UDP client group[x], i.e. to
6.
receive commands and send configuration frames
SendCfgOnUDP[x] – Send configuration frame 2 (CFG-2) on UDP for client group[x]
7.
It is possible to turn off/on the UDP data communication either by setting the parameter
SendDataUDP[x] to Disable/Enable locally in the PMU or by sending a C37.118 or IEEE1344
command frame (
C37.118 standard.
However, such a remote control to stop the streams from the client is only possible when the
parameter
client is stored in the IED, i.e. if the IED is rebooted for some reason, the state of the stream will
remain the same.
If the parameter
the clients are ignored in the IED.
It is recommended not to set the parameter
multicast. This is because if one of the clients sends the
receiving the frames.
The UDP implementation in the IED is a UDP_TCP. This means that by default, only the data frames
are sent out on UDP stream and the header frame, configuration frame and command frame are
