*The input/output circuit external
power supply (24 VDC) must be
prepared by the customer.
Note) In the customer's system, do not
ground the + side of 24V power
supply prepared by customer for
connect to the controller.
(related with emergency stop and
parallel input/output) If it
connects with the controller
under the condition that the +
side is grounded, it will lead to
failure of controller.
