NOTE
Xm+0.0 through Xm+0.7 are DI pins for which a common
voltage can be selected.
That is, set up a setting pin XB1 on “0V” side, set up a setting
pin XB2 on “+24” side, by connecting the DICOM0 to the
+24V power supply, a DI signal can be input with its logical
state reverse. If, however, a cable is connected to ground,
it has the same effect as inputting an ON state DI signal.
To prevent this from occurring, set up a setting pin XB1 on
“+24” side, set up a setting pin XB2 on ”0V” side, the
connection of the DICOM0 to the 0V power supply is
recommended wherever possible.
It is set up as follows at the time of factory shipping.
Setting pin XB1 : “+24” side
Setting pin XB2 : “0V” side
