Input signal
Figure 4.3-8 shows the logic when a “Select command (Local-ON-Control)” signal is applied to
the SOFTSW1 function. The input signal is provided when “On” key is pressed on the IED
front panel; the input-point is not required to be mapped. Note that the user should set scheme
switch [S4301-CTRAHMI] to SBO when the operation from the IED front panel is performed;

Command “Local-On-Control”
SOFTSW1 function (Function ID: 522001)
Either “SBO mode” or “DIR mode”
(e.g., “ctlmodel” in IEC61850*)
“Automatic sequence control function (AQEQ)§” in progress
“S4301_OSD_CSF”
(522001_8F0A041F49)
Figure 4.3-8 Select logic for ‘ON’ operation at the IED locally in SOFTSW1†
†Note: To identify the output points of the other SOFTSW logics, see Table 4.3-9.
‡Note: Signal “select condition” is provided. See Figure 4.3-12.
§Note: The SOFTSW1 function is blocked when the ASEQ function is in operation.
Output signal for monitoring
When the state of “select condition” is true, the SOFTSW1 function can issue an output signal
“Select success” at the output-point “S4301_OSD_CSF”.
Note: The signal “S4301_OSD_CSF” is the same signal as shown in Figure 4.3-6. If the
input signal “Local-ON-Control” is not true, the SOFTSW1 function returns to the
“Wait for a command” stage.
(iv) Receiving “Select command for Off operation” from the front panel
Input signal
Figure 4.3-9 shows the logic when a “Select command (Local-OFF-Control)” signal is applied
to the SOFTSW1 logic. The input signal is provided when the user presses “OFF” key on the
IED front panel; the input-point is not required to be mapped.
