section 103, Companion standard for the informative interface of protection
equipment.
20.6.1.2 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 fibres, 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
