8. Move down to the next cell (RP1 P
ort Config). This cell controls the type of serial connection. Select between
K-Bus or RS485.

9. If using EIA(RS)485, the next cell (RP1 Comms Mode) selects the communication mode. The choice is either
IEC 60870 F
T1.2 for normal operation with 11-bit modems, or 10-bit no parity. If using K-Bus this cell will not
appear.

10. If using EIA(RS)485, the next cell down controls the baud rate. Three baud rates are supported; 9600, 19200
and 38400. If using K-Bus this cell will not appear as the baud rate is fixed at 64
kbps.

6.2 IEC 60870-5-103
The specification IEC 60870-5-103 (Telecontrol Equipment and Systems Part 5 Section 103: Transmission
Pr
otocols), defines the use of standards IEC 60870-5-1 to IEC 60870-5-5, which were designed for communication
with protection equipment
This section describes how the IEC 60870-5-103 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
IEC 60870-5-103 standard.
This section should provide sufficient detail to enable understanding of the standard at a level required by most
users.
The IEC 60870-5-103 interface is a master/slave interface with the device as the slave device. The device conforms
to compatibility level 2, as defined in the IEC 60870-5-103.standard.
The following IEC 60870-5-103 facilities are supported by this interface:
● Initialization (reset)
● Time synchronization
● Event record extraction
● General interrogation
● Cyclic measurements
● General commands
● Disturbance record extraction
● Private codes
6.2.1 PHYSICAL CONNECTION AND LINK LAYER
There is just one option for IEC 60870-5-103:
● R
ear serial port 1- for permanent SCADA connection via RS485
The IED address and baud rate can be selected using the front panel menu or by a suitable application such as
MiCOM S1 Agile.
