Input signal generated at the local-end
Figure 4.8-6 shows the Select logic when "Select command On (Local-ON-Control)" signal is
applied to the DPOS01 function. The signal is provided when an "On" key is pressed on the
IED front panel; the user is not required to take account of mapping. Note that the user should
set the scheme switch [DPOS01-CTRAHMI] to SBO when operation from the IED front panel
is required, we discuss how to set this in chapter
Output signal to BO
When the "select condition" signal is true, the DPOS01 function can issue a "Select success"
signal at the output-point "DPOS01_OSL_BO_CSF".
Note: The "DPOS01_OSL_BO_CSF" signal is the same as the signal shown in Figure
4.8-2. If the input signal "Local-ON-Control" is not true, the DPOS01 function
returns to the "Wait for a command" stage.
