4. For all controllers in your project, re-adjust the Watchdog Times
to their individual optimum values.
5. Start the project and let it run for a while.
6. If you encounter controller errors due to a Watchdog Time that
is too short, increase the Watchdog Time. Otherwise, continue
with the network optimization.
Check HH Status
In the Control Panel, click the HH Status tab.
The HH Status displays the following information.
Read the RspT min parameter. This is the minimum time needed for
the communication modules (COM) of two controllers to talk to each
other. Refresh RspT values with Communication>Update HH State, if
Token Passing is OFF.
TIP
After these modifications, you must re-compile the
project with the Code Generator and download the
routines in the controllers again.
Parameter Explanation
Bus Cycle Time Time in milliseconds for a Token cycle. The value is 0, if Token Passing is
off (any Cleanroom profile).
Resource Name of the controller

, based on the network hardware and topology. This parameter
cannot be changed by the user.
•
If Link Mode is TCS TOKCYC (Token Passing ON), RspT is part of the Bus
Cycle Time.
