10-1 Controller Link Network Diagnostic Tool
10-1-6 Node Status
10-18
Item Description
Number of
controller
changes Displays the number of times that the polling node was changed.
Polling node changes are counted when the power supply is turned OFF to the polling node,
but can also be counted when transmission path errors occur.
Number of
active node
changes Displays the number of times the number of nodes participating in the network increased or
decreased.
Active node changes are also counted when the power supply is turned ON to a node and the
node joins the network. They can also be counted when transmission path errors occur (even
if the power supply is not turned OFF and ON).
•
Click the Copy Button to copy the data for the transmission status counters to the
clipboard. The data on the clipboard will be in CSV (text) format. The data on the
clipboard can be pasted to an editor, word processor, or spreadsheet software.
Note
•
The values of the transmission status counters are counted from the time the power is
turned ON to a Controller Link Unit/Board or the Unit/Board is reset. The counters will
not count past 255.
•
The transmission status counters cannot be cleared directly.
Note The various transmission status counters cannot be used alone to determine
transmission path errors. Use them as guidelines for checking the transmission status
of the network.
