Input signal generated at the local-end
Figure 4.2-6 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.
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
4.2-2. If the input signal "Local-ON-Control" is not true, the DPOS01 function
returns to the "Wait for a command" stage.
