4.1-13 for PLC#1, Table 4.1-14 for PLC#2, Table 4.1-17 and Table 4.1-19 for output
signals.

Input signal from the PLC function
Figure 4.1-30 depicts the operate logic when an "Operate command Off (PLC-Off-control)"
signal is generated by the PLC function. There are two input points for reception of this
command signal, like the signal "Operate command On (PLC-On-control)", That is, if an
interlock check is required, apply the signal at connection point (PLC#3: i.e.
DEV01_OP_INTERLOCK). If, on the other hand an interlock check is not required, apply the
signal at the other connection point (PLC#4: i.e. DEV01_OP_COMMAND). PLC#3 and PLC#4
are denoted as PLC#1 and PLC#2 in Table 4.1-2.
Output signal to BO
The DPOS01 function, in Figure 4.1-30, can issue an "Operate" signal at output-point
"DPOS01_FEX_BO", when the DPOS01 function determines that the signal "PLC-Off-Control"
is true.
