Input signal from the PLC function
Figure 4.1-10 shows the Select logic when a "select command On (PLC-On-Control)" signal is
generated by the PLC function. There are two input points for reception of this signal: the
former connection point, (PLC#1) is used for the reception of the select-command requiring the
interlock check, the later connection point, (PLC#2) is used for the reception of the select-
command not requiring the interlock check. That is, for the DPOS01 function, when the "Select
command On (PLC-ON-Control)" signal generated in the user-programmed logic is applied for
the select logic and when the interlock check is required in the select logic, use the connection
point (PLC#1: e.g.DEV01_CL_INTERLOCK). Alternatively, if the interlock check is not
required, use the other connection point (PLC# 2: e.g., DEV01_CL_COMMAND) for the
injection. PLC#1 and PLC#2 is shown in Table 4.1-1.
Output signal to BO
The DPOS01 function, in Figure 4.1-10, can issue a "Select success" signal at the output-point
"DPOS01_OSL_BO_CSF"
Note: The "DPOS01_OSL_BO_CSF" signal is the same signal as that shown in Figure
1
4.1-2.
