IEC 60870-5 CS 103 communication

The IEC specification IEC 60870-5-103: Telecontrol Equipment and Systems, Part 5:
Transmission Protocols Section 103 defines the use of standards
IEC 60870-5-1 to IEC 60870-5-5 to perform communication with protection equipment. The
standard configuration for the IEC 60870-5-103 protocol is to use a twisted pair EIA(RS)485
connection over distances up to 1000m. The relay operates as a slave in the system,
responding to commands from a master station.
1.2.5

DNP3.0 communication

The DNP 3.0 protocol is defined and administered by the DNP User Group. Information
about the user group, DNP 3.0 in general and protocol specifications can be found on their
website: www.dnp.org

Second rear communication port (SK4)

There is a hardware option of a second rear communications port, which will run the Courier
language. This can be used over one of three physical links: twisted pair K-Bus (non-polarity
sensitive), twisted pair EIA(RS)485 (connection polarity sensitive) or EIA(RS)232.
The settings for this port are located immediately below the ones for the first port as
described in previous sections of P44x/EN IT. Move down the settings until the following sub
heading is displayed.
The next cell down indicates the language, which is fixed at Courier for RP2.
The next cell down indicates the status of the hardware, e.g.
The next cell allows for selection of the port configuration.
The port can be configured for EIA(RS)232, EIA(RS)485 or K-Bus.
In the case of EIA(RS)232 and EIA(RS)485 the next cell selects the communication mode.
The choice is either IEC 60870 FT1.2 for normal operation with 11-bit modems, or 10-bit no
parity.
The next cell down controls the comms. port address.
