Block PID Block Description PID control function block is an algorithm that produces an output signal in response to the measured variable and the set point The PID function block allows the user to choose either a IROUT OUT RCAS OUT BKCAL OUT standard PID control equation Ideal or a robust PID equation defined by Honeywell This selection is defined in the PID FORM parameter The output has three terms Proportional Integral and Derivative The output is adjusted by tuning constants Three tuning constants are contained in the ideal PID equation The robust PID uses four tuning constants 1 GAIN is the tuning constant of the Proportional term 2 RESET is the tuning constant of the Integral term FLOWSERVE Logix 340010 Digital Positioner FCD LGENIM3402 00 10 07 3 RATEis the tuning constant of the Derivative term RATE is usually modified by a lag which is set at some fixed ratio higher than the rate time to create a rate gain No lag occurs with the rate in this implementation 4 OUT LAG is the fourth tuning constant used in the robust PID it adds roll off to the output response The action is similar to PID with rate gain PID Ideal and PID Robust The ideal equation is a parallel or non interacting implementation of PID control using three tuning constants It automatically fixes OUT LAG to 16 times the RATE time constant This produces response characteristics equivalent to the algorithms used in TPS pro
