Do-more Designer's approach to control loop programming makes PID control an extremely smooth process. PID has never been a one-size-fits-all method so why do most controllers treat PID programming that way? With BRX PLCs, you get modular, interchangeable, independent and run-time configurable control loops to match your exact needs.
Rather than embedding all of the PID parameters like alarm handlers, filters, scaling and Ramp / Soak tables within the PID instruction itself, these are all handled by separate instructions allowing for easy customization for whatever control algorithms are used.
When you are ready to tune the loop, Do-more Designer has many tools like PID Overview and PID View with Auto-tune that you can use to quickly get your process tuned and operating properly.
Use the PID View with Auto-tune to monitor, record and tune your PID loops. The Auto-tune feature will set optimal values for the P, I and D terms in order to get the ideal response from the control system. It will manipulate the PID's output then measure the rate of change, overshoot and response of the process variable. You can then save the newly calculated constants to use in other loops or add to the PIDINIT instruction.
