2.2 Power supply
The option I/O interface uses an external 24V power supply. Be sure to always connect
the 24V and ground terminals of the external power supply to pins P.COMxx and N.COMxx
of the OPT. DIO connector on the controller.
An error is issued when the controller power is turned on if the external 24V power supply
is not connected.
c
CAUTION
Always use different ID when two or
more option I/O interface units are
used. If different units have the same
ID, an option setting error is issued
and correct operation cannot be
guaranteed.
c
CAUTION
Do not keep supplying the external
24V DC power to the optional I/O
interface while controller power is off.
The controller might malfunction if
the external 24V is continuously
supplied.
