Technical manual
There is a default header file, named "ieee1344header.txt", located in the "tools" folder
in the IED. The user is allowed to access and update this text file and write it back to
the IED using a FTP client (e.g. Filezilla).
If the user-defined (updated) header file is larger than 1400 bytes, then it will be
truncated to 1400 bytes in both IEEE C37.118 and IEEE1344 protocols.
Both PMU reporting instances are using the same header file (ieee1344header.txt) and
this header file is used for both IEEE C37.118 and IEEE1344 protocols.
• Commands are machine-readable codes sent to the PMU/PDC for control or
configuration.

Short guidance for use of TCP

Port 7001 is used by the SPA on TCP/IP (field service tool). If the port
is used for any other protocol, for example C37.118, the SPA on
TCP/IP stops working.
The IED supports 8 concurrent TCP connections using IEEE1344 and/or C37.118
protocol. The following parameters are used to define the TCP connection between the
IED and the TCP clients:
1. 1344TCPport– TCP port for control of IEEE 1344 data for TCP clients
2. C37.118TCPport – TCP port for control of IEEE C37.118 data for TCP clients
As can be seen, there are two separate parameters in the IED for selecting port numbers
for TCP connections; one for IEEE1344 protocol (1344TCPport) and another one for
C37.118 protocol (C37.118 TCPport). Client can communicate with the IED over
IEEE1344 protocol using the selected TCP port defined in 1344TCPport, and can
communicate with the IED over IEEE C37.118 protocol using the selected TCP port
number in C37.118TCPport.
All the frames (the header frame, configuration frame, command frame and data frame)
are communicated over the same TCP port. The client can request (by sending a
command frame) a configuration and/or header via the TCP channel and the requested
configuration and/or header will be sent back to the client (as Configuration frame/
Header frame) over the same TCP channel.
Once the TCP client connects to the IED, the client has to necessarily send a command
frame to start a communication. As shown in Figure 30, the IED can support 2
PMUREPORT instances and the client has to specify the PMU ID Code in order to
know which PMUREPORT data needs to be 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,
