Micro800 PID instruction in CCW

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.

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!

i am curious how to configure a cascade loop control using a micro850 plc

Thank you Tim, all your videos are very helpful. Im having a a problem with my the any to word function, it doesnt seem to convert for my AO and just transfers the the real number number across. got any ideas why this is?

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.

Your a legend Tim, love your videos. Ive got a funny one for you. I dont have ANY_TO_REAL or ANY_TO_INT function blocks available to select. there are ANY_TO_LREAL and ANY_TO_LINT. Any thoughts?

Hi, Tim I am trying to change my PID Gains like you did in the video but they keep changing back to 0.0. Any ideas?

QUICK question, why did you have to turn the potentiometer to run the fan???

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?

I understand why you type variables and did not like to link function blocks with lines. But for beginners like me its much easier to understand.

Hi Tim. your video is really good!, I would like to know how to use the PID for temperature control using micro 820.

Great content!

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

Muy buen video, gracias. Desde Córdoba Argentina.

sir i have a problem during build the ladder showing input variable unwired

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!

You switched your feedback and process variable near the end right?

How many control loops can an Micro850 run at the same time?

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.

Please make training video on hsc control with pid

Thanks your content is very useful

Sir can u make video how to configure, control and monitor the plc I/o through webserver ..

Hey Tim, if you don't mind me ask, what's the name of the game your son is playing?

Good job!! Excellent explanation!!

Hi Tim. Do you have, or plan to make, any videos about how you got your business off of the ground and have any advice for people looking to start a similar business? It would be interesting to know the challenges you faced and what you wish you knew in the beginning.

Tim, in CCW, go to Tools > Options > Environment > Fonts and Colors and drop that guy down to a pt 6. You can change the font to something a little less blocky as well. Also, anything built with Visual Studio, like CCW, I would have a ton of graphical glitches with. You might want to try and go to Tools > Options > Environment and then UNCHECK "Automatically adjust visual experience based on client performance." That fixed some of the graphic issues I was having with CCW. Now, I only mildly can't stand CCW instead of completely hating it like I did before.

Thank you Tim, it is very much appreciated for the time it takes to do this after a full day of work.
