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
Function block with user defined functions in control direction, I103USRCMD. These function blocks
include the FUNCTION TYPE parameter for each block in the private range, and the INFORMATION
NUMBER parameter for each output signal.
Status
The events created in the IED available for the IEC 60870-5-103 protocol are based on the:
• IED status indication in monitor direction
Function block with defined IED functions in monitor direction, I103IED. This block use PARAMETER as
FUNCTION TYPE, and INFORMATION NUMBER parameter is defined for each input signal.
• Function status indication in monitor direction, user-defined
