To verify keeper signatures:
1. In Network menu, choose Keeper Status
2. If any keepers are invalid, select the node(s) and click Update
Keeper
To verify scanner signatures:
1. In Network menu, choose Scanner Signature Status
2. If any scanners are invalid, download the RSNetWorx project to
the processors that indicate a scanner signature mismatch (you
may have to follow additional troubleshooting procedures in
RSNetWorx software to correct the scanner signature mismatch).
Merge-Save Functionality
When you add or delete nodes or when you add, modify, or delete I/O
map table entries, only those processors on the network whose
ControlNet schedules need to change are required to be in Program
mode. This feature requires RSNetWorx for ControlNet software
version 1.6 or later.
During the save operation, RSNetWorx software gives you two
options:
• Optimize schedule for all connections: RSNetWorx software
recalculates the ControlNet schedule for all the nodes on the
ControlNet network. The new schedule is downloaded to all the
processors. The processors close all of their existing connections
and then reopen their connections according to the new schedule.
This option requires that all the processors be in Program mode.
• Merge changes into existing schedule: RSNetWorx software
merges the pending changes into the current ControlNet schedule.
The new schedule is only downloaded to those processors that are
affected by the change. Only those processors that are affected by
the change have to be in Program mode. All other processors on
the network can remain in Run mode and their connections
remain open. This option is only available if the current schedule
can accommodate the pending changes and if the ControlNet
network parameters (such as NUT, maximum scheduled address,
maximum unscheduled address, or media redundancy) do not
change.
Important: Performing a download via RSNetWorx software may
require all the processors to be in Program mode.

online help systems included with RSNetWorx for ControlNet and
