6. 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.

7. If the optional fibre optic connectors are fitted, the RP1 PhysicalLink cell is visible. This cell controls the
physical media used for the communication (Copper or Fibr
e optic).

8. Move down to the next cell (RP1 Time Sync). This cell affects the time synchr
onisation request from the
master by the IED. It can be set to enabled or disabled. If enabled it allows the DNP3.0 master to
synchronise the time on the IED.

7.3.9.1 DNP3 CONFIGURATOR
A PC support package for DNP3.0 is available as part of the supplied settings application software (MiCOM S1 Agile)
to allow configuration of the device's DNP3.0 response. The configuration data is uploaded from the device to the
PC in a block of compressed format data and downloaded in a similar manner after modification. The new DNP3.0
configuration takes effect after the download is complete. To restore the default configuration at any time, from
the CONFIGURATION column, select the Restore Defaults cell then select All Settings.
In MiCOM S1 Agile, the DNP3.0 data is shown in three main folders, one folder each for the point configuration,
integer scaling and default variation (data format). The point configuration also includes screens for binary inputs,
binary outputs, counters and analogue input configuration.
If the device supports DNP Over Ethernet, the configuration related settings are done in the folder DNP Over
Ethernet.
7.4 MODBUS
This section describes how the MODBUS standard is applied to the Px40 platform. 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
MODBUS standard.
The MODBUS protocol is a master/slave protocol, defined and administered by the MODBUS Organization For
further information on MODBUS and the protocol specifications, please seethe Modbus web site
(www.modbus.org).
