Input signal from the PLC function
Figure 4.1-12 shows the select logic when a "Select command Open (PLC-Open-Control)" signal
is generated by the PLC function There are two input-points for the reception of this signal,
unlike in the signal "Select command Closing (PLC-Closing-Control)" where four are available.
That is, if interlock checking is required, use the connection point (PLC#1:e.g.,
DEV01_OP_INTERLOCK). Alternatively, if the interlock check is not required, use the
connection point (PLC#2:e.g., DEV01_OP_COMMAND). PLC#1 and the PLC#2 are shown in
Table 4.1-3.
