5-14-4 Setting the Node Response Time — T: Watchdog Timer
If an error occurs during communications between the Controller Link Support
Software and a node, the node may not be able to send a response to a request
sent by the Controller Link Support Software. “T: Watchdog timer” is used to set
the maximum node response time to be monitored. Failure to send a response
within this time will be treated as an error.
Note
1) If the node does not send a response within the maximum node response
time, a response timeout error will occur and an error message will be dis-
played.
2) Normally, the maximum node response time can be set to the default (5 se-
conds). If, however, a response timeout error frequently occurs, take one of
the following actions:
•
Increase the maximum node response time.
