@@abdelrahmansaad9525 The simple fix would be to re-tune the loop up around 4 psi where the process has a higher gain. This would cause the control to be sluggish or slower when controlling back down at 1 psi where the process gain is lower, but at least the loop wouldn’t oscillate when controlling around 4 psi. If you needed the loop to have the same response throughout the range of control on a non-linear process you would use a signal characterizer. Watch this video for a demonstration of a signal characterizer: kzbin.info/www/bejne/lZCocneYZ6uLrqcsi=ibbCDctz4lD2eC_4

@TheWorldCaster do you have Studio 5000?

@@malcolmandthebends2914 your welcome!

You used the same values from the video?

@ yess

Sorry, I don’t follow your question. Are you saying you have a problem with the controller working with your valve actuator?

@AutomationCliff Nope, I don't have any problem, but I'm just curious about this topic. And if, for example our valve operated by controller, which pressure going to actuator, same 3-15 psi, or this is only control air and for actuator actuation going another air?

@@aminsheilaandkiddos1686 Yes, the 1756 modules are hot swappable. You can replace the with power on the chassis. You will want to make sure the I/O connected to the module is not in service or being used to control a process, an explosive atmosphere is not present and the firmware of the new module matches the one you are replacing.

@@aminsheilaandkiddos1686 Also make sure in the module configuration it is not configured to fault the CPU if the module is removed.

@@makeshmuthusamy4024 you’re welcome!

The machine used in this video is a Ridgid Model 535 Threading Machine. You should be able to find a manual for it online.

Yes, I have recently decided to start making some more videos. Stay tuned!

I used DeltaV Simulate to build this. Do you have access to DeltaV?

@RDCINST Yes, I have access. Can you share the control stedio configuration? I would like to know how to use dead time, lag time, and lead time along with FF gain to use feedforward compensation. By the way , I watched so many videos explaining feedforward compensation, but nobody delivered the concept like you, especially when you explained how to get the ff gain.

@@Deiski76 here is a video showing the Control Studio function block logic. Enjoy! VIEWER REQUESTED: Dynamic Feedforward Logic - DeltaV 12.3.1 kzbin.info/www/bejne/b6TdhHluea6UkMk

@RDCINST Thank you so much. Now everything is clear. Very informative video , I do appreciate it 👍

@@Deiski76 Awesome! Happy to help.

@@arlethralde3706 to the left of the Ethernet/IP module? It’s the controller (CPU) module.

@@qaispayman2934 you are welcome. I’m glad you could make use of this.

@@radiateurfou185 it goes back to the oil tank.

​@@AutomationCliff I only see the water pipe on the left of the weir. does the oil go there too?

@@radiateurfou185 If go to about 5:00 in the video you will see the water piping on the left like you mentioned and the yellow oil piping on the right.

@@AutomationCliff Yes but the oil on the left which is under the spilling threshold, how do it go to the right?

@@radiateurfou185 sorry I understand what you are saying now. In a three-phase separator like this one, the interface between the water and oil is maintained. This is done by measuring the oil-water interface and then throttling the water valve - there will always be oil there in normal operation. If the feed starts to have more oil, more oil spills over the weir if the feed has more water, it will cause the interface to rise, but the automated water valve would open more to bring it back down. If an operator actually wanted to push all that extra oil over, they would have to raise the setpoint for the interface up, but they would risk spilling water over into the oil and the oil wouldn’t be as pure. This process is continuous. It has a constant oil-water-air mix fed into it and constantly produces separated oil, water and air. As more oil comes in, the oil you are concerned about will spill over and exit out the pipe on the right. I hope this makes more sense now.

This trainer board was designed and built in-house. DeltaV parts were sourced from Spartan Controls, electronic connectors from DigiKey and the aluminum board was cut out using a waterjet cutter at Red Deer Polytechnic (RDP) formerly know as Red Deer College (RDC).

The three threads of engagement for wrench-tight is approximate. Tighten until you have it facing the way you want it and with approximately 3 threads engaged from hand tight. Once you do it a few times and get a feel for it, it will make sense.

@@bolisorac3298 awesome!

This is explained starting at 16:00 in the video.

Ok, is this a Foundation Fieldbus device? Are you not able to make this mode change from DeltaV? What version of DeltaV are you using?

I have never tried making this mode change from a Trex Communicator. Is your system using Foundation Fieldbus? Otherwise, I don’t think you can use the Trex to make the change.

No problem! I’m glad you enjoyed!

Thanks! My pleasure!

Thanks!

Liquid? Or gas?

This trainer was purchased from DarbyTech. You would have to reach out to them for pricing: www.darbytech.ca/

I haven’t done this before, but if I was asked to do this I would look into using a DeltaV OPC server to provide the data to Ignition. I’m sure this has probably been done before, so I would contact Inductive Automation and Emerson for some guidance on the best way to do this. DeltaV Books Online probably has information on configuring the OPC server and Inductive Automation probably has information on connecting to an OPC server on their website. Good luck!

Thanks for reaching out! I no longer have access to this equipment, so I cannot make other videos. If I do access the equipment in the future I will add it to my list of video requests.

Cool! What is it controlling pressure on?

I’m sorry. I’m not familiar with ORCAView. It is a different piece of software in this video. This video is for Emerson’s DeltaV control system, not ORCAView.

Hello to you too!

The modules are hot-swappable on the ControlLogix series. Confirm in the documentation, but you should be able the change the card out with the PLC powered up. If the PLC is controlling a live process make sure to connect to it with Studio 5000 and check the module isn’t configured to fault the controller when it is disconnected. Otherwise, if you feel more comfortable doing a shutdown, you can power off the PLC by opening in the door on the power supply and using the power switch to power it down.

@@AutomationCliff I appreciate the response! Thank you very much! I love your content and just subscribed. Thank you for all the info.

You’re welcome!

Are you talking about an orifice used for choked flow?

@@AutomationCliff yes do you have a class for gas choked flow restriction plate (no measurement)

@@donalddorn7507 Sorry I do not.

Yes, I agree. If I have access to this equipment again in the future, I will definitely consider making a second video. Thanks for the feedback!

Thanks for the feedback! I will consider making a second video if I have access to the equipment in the future.

I haven’t worked with DeltaV’s web server. I would suggest reaching out to Emerson for details on this.

You’re welcome!

Sorry, I do not. Emerson offers training.
