Mode Structure
Terry Blevins
The PID block mode parameter as originally defined by ISA50 determines the source of the block setpoint and the source of its output. This mode parameter is structure to contain four attributes: Target – The mode of operation requested by the operator Actual – The mode of operation that may be achieved based on the … Continue reading » Read the full text.

The A, B, Cs of Controller Tuning
Gregory K McMillan
All of the major tuning methods end up with the same expressions for PID gain, reset time, and rate time when the tuning objective is maximum disturbance rejection. Differences come down to tweaking of the a, b, and c coefficients. Furthermore the use of external-reset feedback (dynamic reset limit), and options such as a setpoint filter, setpoint rate limit, and an enhanced PID for wireless eliminate the need to retune…

Mode – Bumpless Transfer
Terry Blevins
As an operator changes the mode of a function block, it is important that this change not cause a sudden change in plant operation. In the ISA50 mode implementation, the status in the backward path plays an important role in providing bumpless transfer. For example, the actual mode of an analog output block will not transfer … Continue reading » Read the full text.

What are the Alternatives to Reduce Noise?
Gregory K McMillan
Nearly all loops have noise. Whether you see the noise is a matter of amplitude, frequency, resolution, and data compression. Signal filters and damping can reduce noise but the penalty is a measurement lag and deterioration in the ability to reject disturbances. Here are alternatives for noise reduction to decrease process variability and increase valve life. read more

Mode – The Role of Status
Terry Blevins
As the ISA50 function block team considered how to improve plant operations through a more comprehensive implementation of mode in the control system, they realized it would be important that the control blocks, such as the PID, be designed to automatically take into account up-steam and downstream conditions that impact control operation. Thus, inputs and … Continue reading » Read the full text.

Future PV Values are the Future
Gregory K McMillan
Control loops have to deal with disturbances and setpoint changes, yet operator displays give a static picture. The simple identification of the loop deadtime and calculation of the process variable (PV) rate of change can be used to provide intelligent trends and future trajectories that not only help the operator but also offer equipment and environmental protection, optimization of setpoint response, and process analysis…

Distributed Control Systems’ Implementation of Mode
Terry Blevins
To ease operator transition from panel-based systems to monitor-based systems, the manner in which first generation Distributed Control Systems (DCS) displayed information often mimicked the way this information had earlier appeared on the control panel. Since the control interface provided by the control panel was familiar and had proven to be effective, a similar presentation … Continue reading » Read the full text…
