NOTE
1 Xm+0.0 through Xm+0.7 and Xm+5.0 through Xm+5.7 are
DI pins for which a common voltage can be selected. That
is, by connecting the DICOM0 CE56(A14) or DICOM5
CE57(B14) pin to the +24 V power supply, a DI signal can
be input with its logical state reversed. 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, the
connection of the DICOM0 CE56(A14) and DICOM5
CE57(B14) pins to the 0 V power supply is recommended
wherever possible.
2 For safety reasons, the emergency stop signal needs to be
allocated to an appropriate bit X0.4 of the addresses for
which the common voltage is fixed. So, it is impossible to
input an emergency stop signal from this operators panel
I/O module. It should be allocated to the builtin I/O module
of the Power Mate or an I/O module supporting the FANUC
I/O Link.
3 For unused DI pins allocated to the addresses for which the
common voltage is fixed, the logic is fixed to 0. For unused
pins allocated to the addresses for which the common
voltage can be selected, the logic is fixed to 0 when the
DICOM0 CE56(A14) or DICOM5 CE57(B14) pin is
connected to the 0 V power supply. When the DICOM0
CE56(A14) or DICOM5 CE57(B14) pin is connected to the
+24 V power supply, the logic is fixed to 1. The logic of the
unused pins is variable when the contact of the DICOM0
and DICOM5 pins is open.
