6. Move down to the next cell (RP1 Baud Rate). This cell controls 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 controls 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 order 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.

3.5 IEC 61850 CONFIGURATION
You cannot configure the device for IEC 61850 using the HMI panel on the product. For this you must use
the IEC 61850 Configurator, which is part of the settings application software.
IEC 61850 allows IEDs to be directly configured from a configuration file. The IED’s system configuration
capabilities are determined from an IED Capability Description file (ICD), supplied with the product. By using
ICD files from the products to be installed, you can design, configure and test (using simulation tools), a
substation’s entire protection scheme before the products are installed into the substation.
To help with this process, the settings application software provides an IEC 61850 Configurator tool, which
allows the pre-configured IEC
61850 configuration file to be imported and transferred to the IED. As well as
this, you can manually create configuration files for all products, based on their original IED capability
description (ICD file).
Other features include:
● The extraction of configuration data for viewing and editing.
● A sophisticated error checking sequence to validate the configuration data before sending to the IED.
Note:
Some configuration data is available in the IEC61850 CONFIG. column, allowing read-only access to basic
configuration data.
