Figure 4.8-22 illustrates the operate logic when an "Operate command Off (Remote-Off-
Control)" signal is applied to the DPOS01 logic. The input-point "DEV01_CONTROL_REQ" is
used for the reception of the "Operate command Off (Remote-Off-Control)".
Output signal to BO
The DPOS01 function, in Figure 4.8-22, can issue an "Operate" signal at the output-point
"DPOS01_FEX_BO", when the DPOS01 function determines that the input signal "Remote-
Off-Control" is true.
