Configuration of Station/Remote switch

Each IED and logical device in the OPC Server has a configuration parameter
defining the OPC node path for the S/R switch that is used for that IED/logical
device. If a logical device does not have an S/R switch path configured, the path
defined in the IED is used instead. At run-time, the S/R path of a logical device can
be read from the OPC Server; the LD S/R switch path is located in the LD node. The
OPC server that has the S/R switch position information must have at least one
signal mapped to the OPC client using this information.
The S/R switch OPC path shall point to an OPC node modeled according to one of
the supported IEC 61850 data classes. The stVal OPC item of the S/R object presents
the state of the S/R switch, 1 = station and 0 = remote. If the stVal item has the
vartype VT_BOOL, VARIANT_TRUE is interpreted as 1 and VARIANT_FALSE
as 0.
The same S/R switch OPC path can be shared by several IEDs/LDs, or each IED/LD
can have an own S/R switch OPC path. The OPC node pointed by the path can be
located in an OPC server providing the S/R information from a physical switch or
from a simulated software switch.
