Hi Tim, Thanks for this video but in case nobody has pointed it out it is incorrect. You have the "Process" Input and the "Feedback" input switched. The "Provess" is actually the PV and Feedback is the feedback of the control output (CV or MV). The Rockwell Documentation confirm this.

Hi Tim. I have a suggestion for a video. Let's say you have a valve (normally closed) the PID will increase the value to start from closed to open, exactly like your fan. Now, lest say you want to start this normally closed valve in fully open state and then PID will lower the value to get the setpoint. I like your videos!

Great video Tim! I have been having trouble retaining my setpoints after edits. I use a real tag for setpoints so I can edit them from an HMI but they wont save when I go offline, do edits and than reload program.

First, thanks for these excellent videos. I have a question, forgive me if you have already answered elsewhere. The topology looks different between when you initially built the project (reference 17:00) and what shows up when you are online (reference 17:30). Specifically it looks like the sources connected to the PID inputs "Process" and "Feedback" have been swapped. Did I miss something? OK, I guess I have two questions; does "Feedback" serve the same purpose as the "Tieback" input on the PID blocks in the old PLC5/SLC controllers?

Hi Bonnie, 17:30 is correct. I accidentally removed the part where I corrected it. I plan on making a supplemental video about it next time I have it setup.

Tim. I am using RA_TEMP_CONTROLLER function block, everything working good, I can make autotuning and PID works perfect, but once I turn the power off and on again I am loosing the PID values, all of them are "0". I do not understand, because set point and other values the PLC is holding them (I am using retained option). How can I hold the PID gains once I turn the power off? thanks!
@maxwellschaphorst8050 3 жыл бұрын
Hey Tim could you make a video on how to use the Micro800 Simulator to simulate a PID control loop with CCW? Is this even possible to do? I'm guessing having the output affect the PV would be difficult to do without any direct correlation. Maybe using an equation to do it.
@TimWilborne 3 жыл бұрын
We have some exercises in the series that can be done in the simulator but eventually you need to get some hardware. Stay tuned.

Hi Tim, I am a little bit confuse about the value put into the Process. Before you download the program, I saw the Process tag name is PID_Command_Speed. After the downloading I found that the Process tag name is Actual_Position. Did you switch those two tags before you download the program? Thank you very much

Hi Tim. I have a project in the company where I work, is about a temperature control. i already did a project using any_to_real and comparators just to activate outputs, but the temperature is taken to much time to stabilize. do you believe the PID could help me? do you give any personalized training?
@TimWilborne 3 жыл бұрын
Hi Heriberto. It is possible but there are too many variables to say for sure. We do training on Studio 5000 and while we may touch on PIDs, it isn't designed to help you program them. twcontrols.com/plc-lab

Hello Tim... is there a way to write the Kc, I and D gains remotely? I've been trying but the "PID_GAINS" variable is not in a "Write mode". There is not much information in the RA manuals. Thanks a lot.
@TimWilborne 2 жыл бұрын
Make sure you are specifying the element such as PID_Gains.Kc. Then you would just move a REAL number to it.

Hi Tim, I hope you respond :D Look, I am trying to make a temperature PID, but on a Micro850, I see that in that PLC I do not have WORD outputs, how can I solve this?? Also to see if it is necessary to make other types of adjustments for the PID, I have a PT100 as a sensor and an SSR to activate my resistors. Thank you in advance for your answer.
