The relay supports the IEC 60870-5-103 remote communication protocol in the
unbalanced transmission mode. The IEC 60870-5-103 protocol is used to transfer
measurand and status data from the slave to the master. However, the IEC 60870-5-
103 protocol cannot be used to transfer disturbance recorder data.
The IEC 60870-5-103 protocol can be used only through the rear connection of the
relay on the optional communication module. Connecting the relay to a fibre-optic
communication bus requires a fibre-optic communication module. The line-idle
state of the fibre-optic communication module can be selected either via the HMI or
the SPA bus. According to the IEC 60870-5-103 standard, the line-idle state is “light
on”. To ensure communication, the line-idle state should be the same for both the
master and the slave device. The connection topology can be selected to be either
loop or star, the default being loop, and either via the HMI or the SPA bus. The
selected line-idle state and connection topology apply irrespective of which rear
communication protocol is active.
The relay uses the SPA bus protocol as default when the optional communication
module is in use. The protocol selection is memorized and is therefore always
activated when the rear connection is in use. The baud rate can be selected either via
the HMI or the SPA bus. According to the IEC 60870-5-103 standard, the baud rate
is 9.6 kbps. When the IEC 60870-5-103 protocol is active, event masks are not in
use. Consequently, all events in the selected configuration set are included in the
event reporting.
The relay is provided with two different selectable configuration sets, of which
configuration set 1 is used by default.
Configuration set 1 is intended to be used when the optional I/O module is not
installed. Configuration set 2 includes additional information, for example output
contact events 6...8 (SO3...SO5) and digital input events 3...5 (DI3...DI5), provided
that the optional I/O module is installed.
Function type and information number are mapped into configuration sets according
to the IEC 60870-5-103 standard to the extent that these have been defined by the
standard. If not defined by the standard, the type of function and/or the information
number are/is mapped into a private range.
