6. CONNECTION OF I/O UNITS TO
MACHINE INTERFACE
141
NOTE
1 Xm+1.0 through Xm+1.7 are DI pins for which a common
voltage can be selected. That is, by connecting the COM1
CE54(A02) 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 COM1 CE54(A02) pin to the 0 V power
supply is recommended wherever possible.
2 If an emergency stop signal is to be input from this
operators panel I/O module, this emergency stop signal
must be allocated to address X0.4 with the common voltage
line fixed, for safety reasons. See Address allocation in
6.7.10 for details of how to allocate the emergency stop
signal.
3 In a twopath Power Mate iD, the emergency stop signal
for the second Power Mate must be allocated to X1.4. So,
it is impossible to allocate the emergency stop signal to a
line beginning at X0 in the twopath Power Mate iD
twopath for safety reasons, because in this operators
panel I/O module, the common voltage line can be selected
for Xm+1.
4 For unused DI pins allocated to the addresses for which the
common voltage is fixed (from Xm+1.0 to Xm+1.7), the logic
is fixed to 0. For unused pins allocated to Xm+1.0 to
Xm+1.7 for which the common voltage can be selected, the
logic is fixed to 0 when the COM1 CE54(A02) pin is
connected to the 0 V power supply. When the COM1
CE54(A02) pin is connected to the +24 V power supply, the
logic is fixed to 1. The logic of the unused pins allocated
to Xm+1.0 to Xm+1.7 is variable when the contact of the
COM1 CE54(A02) pin is open.
