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 […]


Integral Settings for ControlLogix PID Enhanced

Introduction to Integral Settings for ControlLogix PID Enhanced (PIDE) In this section, we’ll discuss the effects of Integral Settings for ControlLogix PID Enhanced. Integral is based on 2 main factors (aside from the gain): The amount of error and time. Moreover, with the PIDE, when we change the Integral gain, […]


Proportional Settings for ControlLogix PID Enhanced (PIDE)

Introduction for Proportional Settings for ControlLogix PID Enhanced (PIDE) In this section, we’ll discuss the proportional settings for Controllogix PID Enhanced (PIDE). It’s important to remember the difference between the PID in ladder logic vs. the function block PIDE. The main difference is that the ladder logic PID instruction is […]

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 […]


Proportional, Integral, Derivative (PID)

Introduction to Proportional, Integral, and Derivative (PID) Proportional, Integral, and Derivative (PID) is a 3-step formula to bring a process to a setpoint, and attempt to hold it there.   The example we will use is a heating process.   We will bring fluid in a pipe up to a […]
