It is possible to see alarms generated in Modbus devices in TAC Vista but these will not automatically create an alarm that appears in the alarm pane.
Create a change of state object that is connected to the alarm signal from the Modbus device.
If the Modbus device goes offline the value will remain at its last polled value. In this case, there may be no alarm generated so you can also monitor the online option in the Modbus device template to give an alarm that the Modbus device is offline.
