Triggering Event Tasks
ControlLogix isolated analog input modules can trigger an Event task. The Event
task causes the controller to execute a section of logic immediately when a
triggering event occurs. You can configure the Event task to be triggered if new
input data is sent at the RPI.
The following graphic shows an Event task dialog box in Logix Designer
application.
Event tasks are useful for synchronizing process variable (PV) samples and
proportional integral derivative (PID) calculations.
