PLCGurus.NET - Creating and Running Trends In Studio 5000

In this video I walk you through the logic necessary to create a sine wave function generator and then use that output in a trend. I will walk you through all of the steps necessary to create and run a trend in Studio 5000.

Thanks for kindness Nice videos

Very interesting, just remember with a trend you will add to the scan time. Sorry big problems and scratching at dirt. Great vid as always, easy to follow, and a great tool

[@vamshikk8843]

Thanks for sharing the knowledge

This is awesome! I saw the Trend folder there before in the organizer, but no real idea how it was used. We have never have them setup on projects for the program nor on plant/equipment commissioning because the other Field Engineers had no idea how to use them. Hell now i know! The trend though looks very similar to the one in FactoryTalk Studio.

Great content

I would also like to have the code, could you make a new video? maybe where you write the logic together with us, and then where we upload the code to have the trends. I thank you, I enthusiastically follow your videos.

Thanks for this Video. I Need such a sine wave Generator to perform frequency respose Tests ( Bode Diagramm with gain and Phase) of my sytems. could i produce smooth sine wave at higher frequency with this Code ?

[@brdn1639]

Why are your tags reset to zero in rung 6 rather than before the computation? In a case where the first scan is started with the wave generator process already enabled, what value is used for Time_Index in the SIN function in rung 4(variable seems uninitialized/undefined)?

[@PLCGurusNET]

Upon tag creation the value will be set to 0 unless explicitly initialized to some other value, otherwise it is retentive meaning it will retain whatever the last value is.

[@brdn1639]

Why is it necessary to have both the "Function" and "Function_Result" tag? I'm confused about having the MOV block with the CPT block on rung 4 instead of just the CPT block. I'm also wondering why the Scale and Offset are defined in parallel with the computation rather than in series before it

[@PLCGurusNET]

Hi there. Thanks for the questions. You're absolutely right I could have just as easily picked off the "Function" tag for the trend. The reason, I suppose, I didn't is that if I wanted to do any further manipulation on "Function" I could do that without having to modify my trend tag. The objective of the video was to show how to setup a trend not necessarily the function generator. I quickly created this to show something interesting in the trend.
As for the MOV instructions, again you're right, I could easily done them in series as well. That said, the instructions will be evaluated top to bottom in the branches as well, so the MOV instructions will be executed before the CPT.

it won't let me trend on studio 5000, every time i hit run it lags for a few seconds and then i get a error saying "path specified invalid or one of the modules not responding

[@brdn1639]

Is the code from your videos available for download?

Would you like it to be? If so head over to PLCGurus.NET and Register at: plcgurus.net/register. Once registered create a Thread Topic in the Rockwell Forum at: plcgurus.net/forums/forum/live-plc-questions-answers/rockwell-allen-bradley-stratix/. Once the thread topic is created I can go ahead and upload the file for you to play with.
Having said that you may want to recreate it yourself!
