6. Move down to the next cell (RP1 Baud Rate). This cell contr
ols the baud rate to be used. Six baud rates are
supported by the IED 1200 bits/s, 2400 bits/s, 4800 bits/s, 9600 bits/s, 19200 bits/s and 38400 bits/s. Make
sure that the baud rate selected on the IED is the same as that set on the master station.

7. Move down to the next cell (RP1 Parity). This cell contr
ols the parity format used in the data frames. The
parity can be set to be one of None, Odd or Even. Make sure that the parity format selected on the IED is
the same as that set on the master station.

8. Move down to the next cell (Modbus IEC Time). This cell controls the or
der in which the bytes of information
are transmitted. There is a choice of Standard or Reverse. When Standard is selected the time format
complies with IEC 60870-5-4 requirements such that byte 1 of the information is transmitted first, followed
by bytes 2 through to 7. If Reverse is selected the transmission of information is reversed.

7.5 IEC 61850
This section describes how the IEC 61850 standard is applied to General Electric products. It is not a description of
the standard itself
. The level at which this section is written assumes that the reader is already familiar with the
IEC 61850 standard.
IEC 61850 is the international standard for Ethernet-based communication in substations. It enables integration of
all protection, control, measurement and monitoring functions within a substation, and additionally provides the
means for interlocking and inter-tripping. It combines the convenience of Ethernet with the security that is so
essential in substations today.
There are two editions of IEC 61850; IEC 61850 edition 1 and IEC 61850 edition 2. The edition which this product
supports depends on your exact model.
7.5.1 BENEFITS OF IEC 61850
The standard provides:
● S
tandar
dised models for IEDs and other equipment within the substation
● Standardised communication services (the methods used to access and exchange data)
● Standardised formats for configuration files
● Peer-to-peer communication
The standard adheres to the requirements laid out by the ISO OSI model and therefore provides complete vendor
interoperability and flexibility on the transmission types and protocols used. This includes mapping of data onto
