This read-write boolean starts a ping operation when set to true, and is automatically reset to false by the device once the ping completes; a management station can also set it back to false to stop an in-progress ping early. An admin sets this to true after configuring the target address and other ping parameters, to actually launch the test. For example, setting this object to true begins the configured ping sequence, and setting it back to false while a long-running ping is in progress halts it.
