Product Description:
You can choose between scanned or interrupt-controlled inputs when you select the digital input
board. The different methods of reading inputs are as follows:
• Scanned inputs
The software scans the digital input boards and updates the data base in
the Advant Controller 450 at regular intervals. This causes the load in the controller to
remain constant, irrespective of the frequency of change at the inputs.
• Interrupt-controlled inputs
The data base in Advant Controller 450 is only updated when the values at the inputs are
changed. This gives more exact time-tagging with event handling of the inputs. Interruptcontrolled inputs also mean a lower load with low to moderate frequency of change.
