2-16 Firmware Maintenance Procedures
If you have added any new CNB modules to your network, adjust the
Network Update Time (NUT) in the new modules. Refer to Setting
CNB Module NUT Timing on page 2-16. Otherwise, return to upgrade
or installation procedures as applicable.
Setting CNB Module NUT Timing
Use the procedure in the following table to adjust the NUT (Network
Update Timing) timing of all the new CNB modules in your system.
1. If this is the first time you have used Network Tools on this PC,
refer to Making First Time Network Tools Settings on page 5-15
and then continue with this procedure beginning at Step 6.
2. Click Start
⇒
Run.
3. Key in this command in the Open entry field:
>ntools -c -pg<
ATTENTION
!
You only need to adjust the NUT timing on new CNB
modules received from the factory. You can skip this
procedure if you have previously set the NUT timing
for all the CNB modules in your system.
The CNB modules must be on a ControlNet that is
plugged into a rack, cabled to the ControlNet, and
have unique MAC addresses in order to change their
ControlNet parameters (as listed in Step 10 on
page 2-17) The ControlNet parameters are updated
for all CNBs on the ControlNet at the same time.
ATTENTION
!
If you are including a Foundation Fieldbus Linking
Device in your application, review the CNB
restrictions covered in the Linking Device
Implementation Guide in Knowledge Builder for NUT
timing data specific to Fieldbus applications.
TIP
If the RSLinx and PCIC driver services for system
communications in ControlNet mode are not
running, this command will start the services.
