*Note: The user can set the type of output signal. When Var is set for scheme switch
[DPSY01-PLSM], the output period of the signal is defined by the setting
[DPSY01-CPW]. When Fix is set, the signal ceases when the 43-switch is changed.
Note: To identify the input and output signal-points of the DPSY02 logic, see Table
††
4.2-15 for PLC#1, Table 4.2-16 for PLC#2, Table 4.2-20, and Table 4.2-21 for

after reaching the time set by the [DPSY01-RST].
Output signal to BO
The DPSY01 function, in Figure 4.2-24, can issue an "Operate" signal at the output point

Control" is true.
