Settings for extra contact health check (special setting, example #3)
Figure 4.2-51 shows an additional setting example for the 43SW scheme; one of the settings is
made hypothetically. That is, the point “DPSY01_OSL_BO_FLG” is actually chosen for the
setting [DPSY01-OSLBORD]; i.e. BO1-RB is not chosen for this selection. This special example
can issue a select command, which is called “operated by internal select function”. The user
does not need to consider the use of a BO circuit for a select command, when there are no BO
circuits available.
