[DPSY01-PLSM], the output period of the signal is defined by the setting applied
to [DPSY01-CPW]. When Fix is set, the signal ceases when the 43-switch is
changed.
Note: To identify the input and output signal-points in the DPSY02 logic, see Table
††
4.2-3 and Table 4.2-4 for PLC#1 to PLC#4, Table 4.2-15 and Table 4.2-16 for
PLC#1/#2 for user configurable conditions, Table 4.2-20, and Table 4.2-21 for the
outputs.
Note: The "Operate failed" signal is issued when a state-change remains undetected
‡‡
following expiration of the setting applied to timer [DPSY01-RST].
Output signal to BO
The DPSY01 function, in Figure 4.2-28, can issue an "Operate" signal at output point
"DPSY01_OEX_BO", when the DPSY01 function determines that the "PLC-Closing-Control"
signal is true.
Receiving "operate command Open" using PLC logic
(vi)
Figure 4.2-29 depicts the reception of the operate command for Open using the PLC function.
These input and output signals and the process are highlighted in the figure below.

Input signal from the PLC function
Figure 4.2-30 depicts the operate logic when an "Operate command Open (PLC-Open-Control)"
signal is generated by the PLC function. There are two points for reception of this command
signal, unlike the signal ("Operate command Closing (PLC-Closing-Control)". That is, if an
interlock check is required, apply the signal at connection point ("PLC#4: i.e.,
DEV01_OP_INTERLOCK"). If, on the other hand an interlock check is not required, apply the
signal at connection point ("PLC#5: i.e., DEV01_OP_COMMAND"). PLC#1 and PLC#2 shown
in Table 4.2-4 should be treated as PLC#3 and PLC#4 here.
