ABB 800xA PID parameters explained
What ABB's PID controller gain and integral time in seconds mean on 800xA, Symphony and Freelance, 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.
Allen-Bradley PID parameters explained
The PIDE block's independent gains — Kp, Ki in 1/sec, Kd in seconds — and the minutes-per-repeat reset of the legacy PID instructions.
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.
Foxboro I/A PID parameters explained
What Foxboro's proportional band, integral and derivative parameters mean, why reset is in minutes per repeat, and which direction makes the action stronger.
GE Mark VIe PID parameters explained
What gain and integral time in seconds mean on GE Mark VIe turbine and process controllers, and which direction makes the action stronger.
Honeywell Experion PID parameters explained
Honeywell Experion and TPS PID parameters: proportional band and reset in minutes per repeat. Smaller band and smaller reset are both more aggressive — the opposite of a gain system.
How to tune a DeltaV PID
What to type on a DeltaV PID block after you have read the loop: GAIN, RESET in minutes per repeat, RATE, and which direction is stronger.
How to tune a Honeywell PID
What to type on Honeywell and Experion: proportional band and reset in minutes per repeat, both of which get stronger when the number gets smaller.
How to tune a Rockwell PIDE
What to type in a PIDE block: dependent versus independent form, PID versus PIDE, and which direction makes the action stronger.
Mitsubishi MELSEC PID parameters explained
What proportional band and integral time in seconds mean on Mitsubishi MELSEC process control, and which direction makes the action stronger.
Ovation PID parameters explained
Ovation PID parameters: gain, and reset in seconds per repeat. A lower reset number is faster integral action — same direction as DeltaV, counted in seconds not minutes.
Rockwell PIDE PID parameters explained
Rockwell PIDE supports dependent and independent gain forms, and the same numbers mean different things in each. How to tell which you have, and what Ki is in each form.
SIMATIC PCS 7 PID parameters explained
PCS 7 uses dimensionless gain with integral time TI and derivative time TD in seconds. What that means on the block, and what to convert before you copy a minutes-based set.
Schneider Modicon PID parameters explained
What gain, integral time and derivative time in seconds mean on Schneider Modicon M340, M580 and Quantum, and which direction makes the action stronger.
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.
