Generating alarms 

You can add logic to a control program to generate an alarm for the following conditions: 

•

 

A sensor has stopped communicating 

•

 

A sensor is not sending a valid value 

  

Alarming for loss of communications 

1 

Tie the Sensor Binder microblock's 

Alarm 

output to an Alarm microblock. The 

Alarm 

output will be true when 

any sensor is in alarm. 

2 

Add a

 

Delay On Make microblock to prevent nuisance alarms during startup or power failure. 

 

 

  

Alarming for sensed values 

1 

To detect if a sensor's value is no longer valid, do the following: 

2 

Assign only one sensor to an ASVI or BSVI microblock.  

3 

Tie the 

Valid 

output to a not microblock since the valid output will be false when in alarm. 

4 

Attach an

 

Alarm microblock to notify the user if the sensor in the ASVI or BSVI microblock has gone into error. 

5 

Add a Delay On Make microblock to prevent nuisance alarms during startup or power failure. 

 
See the 

Microblock Reference

 for details of each microblock's alarming conditions.
