7.3 IEC60-870-5-103
The specification IEC 60870-5-103 (Telecontrol Equipment and Systems Part 5 Section 103:
Transmission Protocols), 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 ADR233B Relay. 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 synchronisation
• Event record extraction
• General interrogation
• Cyclic measurements
• General commands
• Disturbance record extraction
7.3.1 Physical Connection and Link Layer
For connecting on IEC 60870-5-103 there are three options:
• Front USB Port.
• Rear Serial port R – for permanent SCADA connection via RS485.
• Rear serial port 1 - for permanent SCADA connection via Ethernet port.
The IED address and baud rate can be selected using the front panel menu or with RTV2
Configurator.
