Input signal from the PLC function
Figure 4.2-12 shows the Select logic when a "select command Off (PLC-Off-Control)" signal is
generated by the PLC function. There are two input points for the reception of this signal: like
in signal "select command On (PLC-On-Control): 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 PLC#2 are shown in Table 4.2-2.
Output signal to BO
The DPOS01 function, in Figure 4.2-12, can issue a "Select success" signal at the output point
"DPOS01_FSL_BO_CSF"
Note: The output point "DPOS01_FSL_BO_CSF" is the same signal as that shown in
