The NE1A-series Controller performs initialization when the power is turned
ON. During initialization, the Controller performs self-diagnosis of the hard-
ware that is required to execute safety functions. The following table shows
the times required to complete initialization from when the power is turned
ON.

delay
(1) With NE1A-series Controllers with unit version 2.0 (including Controllers
that support EtherNet/IP), an online delay time of 5 s is added after the
initialization has been completed to allow time for other devices to start.
(2) After the initialization has been completed, the NE1A-series Controller
checks for duplicated addresses on the DeviceNet network and then joins
the network (i.e., goes online). After the Controller connects to the net-
work, the NS indicator lights or flashes green. This processing takes a
maximum of 2 s.
