Ping echo request transmission timing
Two types of echo request transmission timing are available: Type 1 and Type 2. (Default: Type 2)
Type1
After sending an echo request, the next Ping echo request is sent after the interval time has elapsed. In
such a case, set the Interval and Timeout so that “Interval
≥
Timeout”.
Type2
After sending an echo request, a Ping echo will either be received or a timeout will occur. The next Ping
echo request is then sent after the interval time has elapsed. In such a case, there is no correlation
between the Interval and Timeout.
