[tommy1983]

I want use it's "Bad Status Alarm" to alarm person on duty  the corresponding sensor was failure! what shall I do to experience 'Bad Status' alarm first?  there is no example project about "Bad Status Alarm".

your question is very generic, can you specify what you are trying to achieve? For ecxample how do you weant to notify? Under what condition do you want to specify a sensor as bad status?

Firstly,Thanks for your replay. I'm a new . I'm building a scada program with labview . There are Modbus TCP/IP controllers and  DS18B20 sensors in  the system controlled by this program . I want use it's "Bad Status Alarm" to alarm person the corresponding DS18B20 sensor was failure.  How could i trigger "Bad Status Alarm" programmatically.

Are you using the DSC module? Can you upload the program you have this far?

The manufacturer talks about an alarm search: the sensor sets a flag and will respond to this alarm search.

Just query for sensor failure status, if it fails make that has a triggering point for alaram (Tower Lamp and Buzzer can be used as a alaram)

Yes,I'm using the DSC module.  My project is big Object-Oriented project . It's too big to upload.  There are two reasons why i want to use "Bad Status Alarm":

1.   There is an one-to-one match between each double point and each DS18B20 sensor, A "Bad Status Alarm" event could tell me all the infomation about the sensor().

2.   Alarms wiil be toke record by DSC module , they will show me the working state  of sensors.
