6. Move down to the next cell (RP1 Meas Period
). The next cell down controls the period between
IEC 60870-5-103 measurements. The IEC 60870-5-103 protocol allows the IED to supply measurements at
regular intervals. The interval between measurements is controlled by this cell, and can be set between 1
and 60 seconds.

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

9. There are three settings associated with this cell; these are:
Setting: Description:
Disabled No blocking selected.
Monitor Blocking
When the monitor blocking DDB Signal is active high, either by energising an opto input or control input,
reading of the status information and disturbance r
ecords is not permitted. When in this mode the device
returns a "Termination of general interrogation" message to the master station.
Command Blocking
When the command blocking DDB signal is active high, either by energising an opto input or control input,
all remote commands will be ignored (i.e. CB Trip/Close, change setting group etc.). When in this mode the
device returns a "negative acknowledgement of command" message to the master station.
7.3 DNP 3.0
This section describes how the DNP 3.0 standard is applied in the product. It is not a description of the standard
itself
. The lev
el at which this section is written assumes that the reader is already familiar with the DNP 3.0
standard.
The descriptions given here are intended to accompany the device profile document that is included in the Menu
Database document. The DNP 3.0 protocol is not described here, please refer to the documentation available from
the user group. The device profile document specifies the full details of the DNP 3.0 implementation. This is the
standard format DNP 3.0 document that specifies which objects; variations and qualifiers are supported. The
device profile document also specifies what data is available from the device using DNP 3.0. The IED operates as a
DNP 3.0 slave and supports subset level 2, as described in the DNP 3.0 standard, plus some of the features from
level 3.
