DeltaV PID parameters explained
What DeltaV's GAIN, RESET and RATE parameters mean, why reset is in minutes per repeat, and which direction makes the action stronger.
PID parameters by control system
What the tuning numbers mean on your system, which direction makes the action stronger, and which algorithm form the controller actually solves.
Honeywell Experion PID parameters explained
Honeywell controllers traditionally use proportional band with reset in minutes per repeat. Both conventions invert the direction of a change.
Ovation PID parameters explained
Ovation expresses reset in repeats per minute, so a higher number is faster integral action. What the PID parameters mean and how they interact.
Rockwell PIDE PID parameters explained
The PIDE block supports both dependent and independent gain forms, and the same numbers mean different things in each. How to tell which you have.
SIMATIC PCS 7 PID parameters explained
PCS 7 uses gain with integral and derivative times in seconds. How that differs from proportional band systems and what to watch when converting.
Yokogawa Centum PID parameters explained
Yokogawa Centum controllers commonly use proportional band with a series algorithm. What that means for direction of action and for converting tuning.
