Input signal from the PLC function
Figure 4.1-12 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 the signal “Select command On (PLC-On-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 PLC#2 is shown Table
4.1-3.
