Time (ms)
The smallest user-configurable repetitive time cycle in milliseconds at
which data can be sent on ControlNet.
Max.
Scheduled

This is the node with the highest network address that can use scheduled
time on a ControlNet link. I/O data is transferred during scheduled time.
RSNetWorx for ControlNet software sets this value. We recommend that
you do not change it.
Max.
Unscheduled
Address
Node with the highest network address that can use unscheduled time on
a ControlNet link. Messaging data is transferred during unscheduled time.
Nodes set at addresses higher than the maximum unscheduled node do
not communicate on the network, for example they will not display in
RSLinx software.
Media
