CODESYS: Implicit variables in SFC

[@raghuprabhu6015]

Hi Tohid, You are a life saver! Your videos are fantastic (prefer no background music please!) I am 60+ years old and retired. My better half said I can not stay at home. So I enrolled in Advanced Diploma in Mechatronics. I was struggling in the class but I am up to speed due to your wonderful videos. I have given the link to my classmates. All of us are thankful. I have a suggestion. Festo Modular Production Stations. If you could do a series on all of them it would be helpful. Also, I am watching your videos and trying to program each one of them in all the different languages, SFC, LD, ST etc. Thank you for your effort in spreading the knowledge.

Dear Raghu, I am really glad that you have found my videos helpful. And congratulations on starting your mechatronics program after retirement. You story should inspire many young people! I have used Festo MPS in my courses and will use it again. However, we have Siemens PLCs for the MPS, and program them using TIA. I may create a simulation and program the stations using CODESYS, for the purposes of this channel. It is a great idea, I think. I can also create videos on GRAFCET programming of the stations! Stay tuned and good luck with your studies/projects.

01_Distributing_GRAFCET 02_Testing_GRAFCET and so on...If you could do a series on this it would be extremely helpful.

Great suggestion! It will take a lot of time to prepare such series, but I will keep that in mind and use my spare time working on it.

Hi, I've follow your tutorial, there is something I did not understand, I create an sfc that work. one of the step have an other sfc inside but this one do not run?, It like it do not initialte. Do you know why ?

Hi. Can you send the simplest example project where you face the problem? Then I will see if I can be of any help.
