Thank you for the video. Can you explain how the pv range affects the tuning parameters values? How do we know how many decimals or what values to start with?
Hi Vladimir, I just finish the course PowerFlex 525 Mastery and it was very interesting. But if you don't mind I would like to learn how the PID instruction work with some VFD as a pump with a flow meter and see how this PID instruction work exactly in a real world situation like trying to control the pump's flow. I check your youtube channel and I could't found any video using the PID instruction working or simulating a real situation. I would be very grateful for your help.
I've considered building a course on PIDs as it was a highly requested topic. I wasn't able to secure hardware required to demonstrate a PID so far... Unfortunately. I'll see if it's something we can add to our calendar.
In my plc 5 pid loop to tune it: using P only, slowly increase the gain until the loop starts to oscillate. Look at the chart and measure the time between the top of each wave. This is the natural frequency of the loop. write that number down. take the found gain(p) and cut it in half to stabilize the loop. Now with the time in seconds for the loop that you wrote down. take 1 and devide it by the number seconds for the loop natural cycle. this number is now your integral time. this is inverse seconds from the allen bradley manual. enter the integral. now you have a good starting point.
It's just a continuous loop to add in an error based on a previous value. It essentially simulates a delayed response, otherwise, the PID would correct itself instantaneously.
Thank you, Vladimir! This video helped me understand how to use the PID instruction in Studio 5000. I am working on a project where I need to convert the PID_Temp instruction in Siemens TIA Portal to a PID instruction in Studio 5000. Do you have a video that explains how to use the PID_Temp instruction in TIA Portal?
Good morning, I have been using my older laptop to talk with my micrologix 800. I am about to buy a new laptop to dabble with PLCs and some computer programming. What is the minimum system you would suggest for a laptop? Thank you for your great videos. I'm still trying for the automation technician job.
Im having an issue with the CPT instruction that you made up everytime I change the setpoint in the PID it just goes straight to the setpoint number no matter what values i put in the PID
thanks master ,, ihave problem with my io ,,, i have compactlogic l16 bbb1b version 20 ,, (i downgrade the firmware from v28 to v20),,, the controller couldnt recognize the embeded io and the expansion io too ,the fault is 16#fd22)....thanks if you can help
Hi Vlad, I followed your video, but my trend was different. Your PV graph is curved, mine pv graph looks like a pulse, it is a little bit squared. You know what it could be?
Check the timer. The logic is based on the timer updating, so if the value is larger it will pulsate. That's my first guess. Also, check if your program is periodic or continuous and what the execution time is.
Glad I'm learning some great tutorials about process controls and tuning PID loops. Thank you!
Fantastic!! Very great info in here!
Simply amazing explanation. Can’t thank enough Vlad for covering this tough subject in automation.
Thank you, I really appreciate the feedback.
Amazing explanation, pretty clear and easy to understand.
One of the best tutorials for Rockwell plc...thank you sir..
Your videos are the best in youtube !!
Thanks a lot for Full explanation end to end it will Help somany members.thx a lot for your efforts
Very useful. Many thanks!
Very good lesson on PID control for temperature control. You are a really good teacher. Thank you.

Thanks so much for your time.
Great Video Vlad
Great explanation Sir
Fantastic video mate...It would be great if we we write structured text in CPT.
Great Video.
Great content! You earned a subscriber sir!
Thank you.
Nice work!

Nice video!! thank you so much for share it.
Great video! On the PID instruction I'm not seeing a change in control variable just the Output % , is that normal?
Hi Vlad very good and very FAST like always , I like to know if you have all this on TH-cam channel what is in your SolisPLC course?
In my plc 5 pid loop to tune it: using P only, slowly increase the gain until the loop starts to oscillate. Look at the chart and measure the time between the top of each wave. This is the natural frequency of the loop. write that number down. take the found gain(p) and cut it in half to stabilize the loop.

Good content 😊
Hi nice channel, you have a new subscriber!! Why you use that expression on the compute instruction? Did you invented that?
It's just a continuous loop to add in an error based on a previous value. It essentially simulates a delayed response, otherwise, the PID would correct itself instantaneously.

Hey Jaqson,
We don't have a video on the PID_Temp instruction in TIA Portal, but we'll add it to our content list.
Thanks for the suggestion.

What is the minimum system you would suggest for a laptop? Thank you for your great videos. I'm still trying for the automation technician job.
Thanks for the video. How do I implement manual, auto and feedback system using this PID function?
Hi Vlad, where can i find the main program you build the PID SR so I can practice and play around with it?
I guess I will have to watch this video like 5 times to understand it.
Is it possible to use a PIDE function for slow opening but fast closing of a steam valve?
Definitely if it's tuned right.
good vids. Will this work on RSLOGIX micro starter lite 500?
yes
@@SolisPLC Vlad, where can i get rs5000 emulator free
@@electrichorror6642 I don't know of any free sources, but you can google around and see some Facebook groups in which people share 3rd party links.
@@SolisPLC thanks bro, i really appreciate it.can you provide Any links or searches to get me started i have the 500 but want 5000
Vlad, my PID is based on high gas pressure. Would the CPT formula still work with my simulator?
Im having an issue with the CPT instruction that you made up everytime I change the setpoint in the PID it just goes straight to the setpoint number no matter what values i put in the PID
That may be an issue with your update rate / timer. If it's too low, it will update instantly.
Hello Solis, how can I use the output to control a relay to power on a heating? I mean a digital output not an analog
How to configuration servo motor ?
thanks master ,, ihave problem with my io ,,, i have compactlogic l16 bbb1b version 20 ,, (i downgrade the firmware from v28 to v20),,, the controller couldnt recognize the embeded io and the expansion io too ,the fault is 16#fd22)....thanks if you can help
See Rockwell knowledgebase answer ID: QA48929, they explain everything to fix that fault on your controller.
because when scaling the analog input in cpt block you mix the input and the output

Why was PID1_CV PID1_PV etc. already a made tag in your case?
I had done some testing prior to making the video; the tag isn't normally there by default.
Is it possible to simulate PID Function in studio5000 ?
Yes
Sorry for the short reply. This is simulated in Logix Designer so development in Studio5000 should be virtually identical.
