4.3.2 Control logics for SBO/DIR modes
For example, the user should set scheme switch [S4301-EN] to On when the SOFTSW1
function is required to be operated. Table 4.3-10 shows all scheme switches for the SOFTSW
functions.
(i) Receiving “select command for On operation” from the remote-end
Input point required mapping
Figure 4.3-6 shows the logic when a “Select command (Remote-ON-Control)” signal is applied
to the SOFTSW1 function. The logic has an input-point “S4301_CONTROL_REQ” for the
reception of the select command. That is, the input-point should be mapped for the IEC61850
communication. The input-point “S4301_CONTROL_REQ” is significant for the SOFTSW1
operation; hence, an operation failure in the IED is indicated if mapping is not performed
correctly. Section 4.3.5 discusses how to map the information of the IEC61850 to the input-
points.
SOTFSW1 function (Function ID: 522001)
“S4301_OSD_CSF”
(522001_8F0A041F49)
Command “Remote-On-Control”
Either “SBO mode” or “DIR mode”
(e.g., “ctlmodel” in IEC61850*)
“Automatic sequence control function (AQEQ)§” in progress

†Note: To identify the input and output points of the other SOFTSW logics, see Table
4.3-6 and Table 4.3-9.
‡Note: “Select condition” signal is provided from select condition scheme. For more
information, see Figure 4.3-12.
§Note: An Automatic sequence control (ASEQ) function can provide sequential signals for
automatic control. The SOFTSW1 function is blocked for the ASEQ function when
it is in operation. For more information of the ASEQ function, see Chapter
Control
and monitoring application: Automatic sequence control function
.
*Note: The SOFTSW1 function can run on either the “SBO mode” or the “DIR mode”. The
user can use the signal “ctlmodel” in the IEC61850 communication.
