‡Note: A “select condition” signal is provided from the select condition scheme. For more
information, see Figure 4.1-13.
§Note: An Automatic sequence control (ASEQ) function can provide sequential signals for
automatic control. The SPOS01 operation is blocked for the ASEQ function when
it is in operation. For more information regarding the ASEQ function, see Chapter
Control and monitoring application: Automatic sequence control function
.

Note: To identify the output signals of the other SPOS logics, see Table 4.1-9.
Output signal to BO
When the “select condition” signal is true, the SPOS01 function can issue a “Selection success”
signal at the output-point “SPOS01_FSL_BO_CSF”.

Note: The signal “SPOS01_FSL_BO_CSF” is the same as the signal shown in Figure
4.1-4. If the “Local-OFF-Control” signal is not true, the SPOS01 function returns
to the “Wait for a command” stage.

Input signal required 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 latter connection point (PLC#2) is used for the reception of the select-
command not requiring the interlock check. That is, for the SPOS01 function, when the “select
command ‘On’ (PLC-On-Control) signal generated in the user-programmed logic is applied, and
