Note: To identify the input and output signal-points of the other DPOS logics, see Table
4.8-14 for PLC#1, Table 4.8-15 for PLC#2, Table 4.8-18 and Table 4.8-20 for output
signals.

Note: The “Operate failed” signal is issued when the state-change is not detected until
after reaching the time set by the [DPOS01-RST].

Input signal generated at the local-end
Figure 4.8-26 illustrates the operate logic when an “Operate command Off (Local-OFF-Control)”
signal is applied to the DPOS01 logic. The input signal is provided when “Execution for Off” is
keyed on the IED front panel.
Output signal to BO
The DPOS01 function, in Figure 4.8-26, can issue an “Operate” signal at the output point
“DPOS01_FEX_BO”, when the DPOS01 function determines that the input signal “Local-Off-
Control” is true.
