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.
