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

[@TohidAlizadeh]

Here is the same video without the background music! Sorry for that, and thanks a lot for the feedback! kzbin.info/www/bejne/g3itpmaYZp2qiM0

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.

[@TohidAlizadeh]

Thanks for the feedback! I am preparing the version without background music and will let you know as soon as it gets ready.

[@VictorSchelsinger]

Hello Tohid. Thats great news.

[@TohidAlizadeh]

I just uploaded the one without music. Thanks again for your 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.

I am a bit busy these days, I will write about this ASAP.

[@serhioromano]

Tohid Alizadeh I did it actually. But i did not use SFCPause, but I used my custom Pause input variable. With that one everything works. I save value of times on pause and resume after pause released.

[@TohidAlizadeh]

Sergey Romanov Good to hear that you have found a solution.

[@hannagantimothyp]

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

[@heberhart61]

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

[@matiasgreenwood4260]

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.

[@TohidAlizadeh]

As soon as the input to the timer goes down the output goes down to zero. You don't need to reset it

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

[@TohidAlizadeh]

Hi Omid. Thanks for your feedback. Here you can see the same video without background music. kzbin.info/www/bejne/g3itpmaYZp2qiM0

[@user-dc9qx5ij3v]

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

[@TohidAlizadeh]

Please have a look at this video: kzbin.info/www/bejne/n2Svn6J7pbWog8U

[@goroman3747]

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

[@TohidAlizadeh]

Well, it could be another solution, however, here I just wanted to show an example of using SFC programming language, as a standard PLC language.

[@realcyan]

your videos are great but the backgroundmusic is so annoying

[@TohidAlizadeh]

I will prepare the one without background music and update you soon!

[@realcyan]

That would be great. Tranks a lot :-)

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.

[@TohidAlizadeh]

Hi there, Here is my email address: [e-mail]. I am quite busy these days, so please do not expect too much help, but I will try my best.
