Example 2:
Name: Laser Overheat
Channel: Laser Temp (V)
Condition: >=
Threshold: 40
Hysteresis: 1
Action: Set channel
Min Time: 5
Set Value: 0
Sequence: near.
Target Channel: Laser Power Switch
This alarm will cause the program to turn off the laser if the Laser Temp becomes greater or equal to
40 for more than 5 seconds. This alarm will not become false until the laser temp falls below 39. If it
is desired that the laser come back on automatically at that time, it would be necessary to define
another alarm using the < condition and the Set Channel Action.
Example 3:
Name: Alarm Alert
Channel: Error
Condition: <>
Threshold: 0
Hysteresis: 0
Action: Alert
Min Time: 0
Set Value: 0
Sequence: near.
Target Channel: near.
This default alarm causes an alarm to be true whenever an error is logged. This ensures that the
Alarm Status indicator at the top of the main program display turns red each time an error occurs.
This alerts the user to the error condition even when the program is not displaying the status tab.
