protocols, and to the section 103, Companion standard for the informative interface
of protection equipment.

Design

General
The protocol implementation consists of the following functions:
• Event handling
• Report of analog service values (measurands)
• Fault location
• Command handling
• Autorecloser ON/OFF
• Teleprotection ON/OFF
• Protection ON/OFF
• LED reset
• Characteristics 1 - 4 (Setting groups)
• File transfer (disturbance files)
• Time synchronization
Hardware
When communicating locally with a Personal Computer (PC) or a Remote
Terminal Unit (RTU) in the station, using the SPA/IEC port, the only hardware
needed is:· Optical fibers, glass/plastic· Opto/electrical converter for the PC/RTU·
PC/RTU
Commands
The commands defined in the IEC 60870-5-103 protocol are represented in
dedicated function blocks. These blocks have output signals for all available
commands according to the protocol. For more information, refer to the
Communication protocol manual, IEC 60870-5-103.
• IED commands in control direction
Function block with defined IED functions in control direction, I103IEDCMD.
This block use PARAMETR as FUNCTION TYPE, and INFORMATION
NUMBER parameter is defined for each output signal.
• Function commands in control direction
Function block with pre-defined functions in control direction, I103CMD. This
block includes the FUNCTION TYPE parameter, and the INFORMATION
NUMBER parameter is defined for each output signal.
• Function commands in control direction
