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 fir st time you have used Network Tools on this PC,
refer to Making First Time Network Tools Settings on page 8-10
and then complete the following steps, starting with Step 6.
2. Click Star t ⇒ Run.
3. Enter this command:
>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 7-16) 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 starts the services.
