Startup Time
(3) There is no online delay time or online processing time when DeviceNet
communications are disabled (i.e., in Standalone Mode).
(4) When the NE1A-series Controller is set for automatic execution when the
power is turned ON, program execution is slower for unit version 2.0 (in-
cluding Controllers that support EtherNet/IP) than for unit version 1.0.
With a program in which a timer is started simultaneous with the start of
NE1A-series Controller program execution, the time from when the power
is turned ON until the timer times out is extended. Therefore, when
changing from unit version 1.0 to 2.0, adjust the set value of the timer.
