Derivative Settings for ControlLogix PID Enhanced

Introduction to Derivative Settings for ControlLogix PID Enhanced (PIDE) Basically, the derivative settings for ControlLogix PID Enhanced will multiply the effect that derivative has in your closed loop system. We use derivative to anticipate, or predict error in the future. Consider this example: Obviously when you open the valve, a Read More »

PlantPAx 4 PID

Introduction to PlantPAx 4 PID We typically use the PlantPAx 4 PID (P_PIDE) in closed loop controls. For example, we have a heating process. This heating process provides a control value (CV) to the heat bands. We monitor the process variable (PV) to see what effect our output has. Our Read More »
