The ControlLogix Moving Average (MAVE) allows you to smooth out a noisy process variable. In other words, if your signal is bouncing around, the MAVE instruction will smooth it out. For example, let’s consider a flow rate. Because of disturbances in the flow of a liquid, the sensor might read different values at any given time. The ControlLogix Moving Average (MAVE) instruction will simply average these results over the past few processor scans. Therefore, the operator will see a more smooth flow rate reading of the sensor. Remember, the MAVE instruction is only available in Function Block (and Structured Text) routines. If you don’t have function block or structured text ability, you can look at the example using a FIFO<\/a> instruction.<\/p>
