2.2 IEC60-870-5-103
2.2.1 Overview
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 P153 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
