Data Limit Detector Process
About Data Limit Detector Process
The Data Limit Detector process monitors signals for the limits you specify.
When any (or all) of the monitored signals exceed their limits, the process ends
and generates a done signal. The done signal from this process is often used to
trigger other processes.
You can configure the Data Limit Detector process to respond to a specific
segment count, amount of time, or sensor signal value.
When you define a Data Limit Detector process, you select the signals you wish
to monitor, set limits on those signals, choose how detector messages are logged,
and choose what action, if any, you want to invoke when the defined limits are
detected.
Example
Assume we want our program to:
• Ramp up to end level 1 at a specified rate (Ramp 1).
• Ramp down to end level 2 at a different rate once the output reaches end
level 1 (Ramp 2).
We can use a Data Limit Detector process to trigger the ramp down process
once our end level 1 is reached.
Ramp 1 process
Start=<Procedure>.Start
Interrupt=Data Limit Detector.Done
Ramp 2 process
Start=Ramp 1.Done
Interrupt=none
Data Limit Detector process
Start=<Procedure>.Start
Interrupt=none
