Offline detection of a LON device in Vista


Is it possible to get a offline alarm in Vista if  the communication with a LON device is lost?


TAC Vista 5.1.7


Vista doesn't have a built-in online/offline detection for LON devices. Vista will set the device offline if it  can't read a value from the device.


Set the "Watch setting" on one of the values in the LON device to "alarm" or "watched", then Vista will continuously poll the value and set the device offline if it can't read the value from the device.
