11. From the Save Configuration dialog box, select Optimize and 
rewrite the schedule for all connections. 
 
12. Click OK. 
It is better to optimize connections. However, in some cases 
involving multiple controllers, the Merge changes into existing 
schedule option is available. This option lets controllers whose 
connections have not changed to continue uninterrupted operation. 
When you merge changes into the existing schedule, those 
controllers whose connections have not changed remain in Run 
mode rather than changing to Program mode. 
13. In the Logix Designer application, save the online project. 
If you change a previously scheduled network, you must reschedule the 
network to apply the changes. For example, if you add I/O to an existing 
ControlNet network, you must reschedule the network for the I/O to become 
active. 
To reschedule an already scheduled ControlNet network, follow this 
procedure in RSNetWorx for ControlNet software. 
1.  From the File menu, choose Open. 
 
2.  From the Open dialog box, select the ControlNet file that matches the 
existing network and click Open.
