CODESYS: SFC programming example- Traffic light control in the intersection #codesys #plcprogramming

-------------------------------------------------------------------------------------------------------------------------------------
In this video, you will learn how to develop a PLC program using Sequential Function Chart (SFC) programming language. Creating the project, adding Steps and Transitions, creating Parallel branches, Adding different types of Actions, and determining a background image in the visualization are covered in this video. Everything is explained through the traffic light control system at an intersection.

Here is the same video without the background music! Sorry for that, and thanks a lot for the feedback!

I have a little bit more complicated SFC. That one is metal washer with different chemicals. And in one step error may occur like for example level of chemicals in a tank lower than allowed. I use SFCPause to pause SFC. But unfortunately when SFCPause is set, timers continue to count. I mean the transitions are not done, but Ton continue to count. For example I enabled SFCPause when timer was T#2s and released it in 5s. Then timer after release will be T#7s. It does not show timer running while SFCPause but it continue to run.

Hi Tohid, great videos. But are you aware of the very loud and distracting sound that is overlaid on your presentation? It would be so good to remove that music.

What traffic light simulation program is being utilized in this video ?

How do I reset the "TON_0.Q"? Because I tried but when continuos to the other steps my "TON_0.Q" stays whit the TRUE signal.

Hi. Thanks to your Tutorial. It will be much appreciated if you can remove background music. Thanks

[goroman]

Ok But why didn't you use like a DRUM function (in Siemens TIA Portal or Schneider Unity Pro XL or a SQO function in Rsloxgix) for progromming a repetitive sequence ...It's better

How were the 2 timers (TON_0.Q and TON_1.Q) added at the end ?

How did you change the background? Where did you put the image?

[realcyan]

your videos are great but the backgroundmusic is so annoying

Hi Tohid,
I'm working on some codesys program and I have some query which I don't understand how to solve.
Can you share me your email id so we can discuss.
Thanks.
