@@PLCprogrammer sir, thank you very much for teaching us traffic simulator. I really need this for my EE assignment but unfortunately I can't see the full ladder diagram. Could you please share it with us or a link to the logixpro file? Thank you so much sir🙏
I liked the count structure of your program. I see one issue: When the walk button is pressed during the amble light transition the walk sign starts rapidly flashing. Pushing the walk button on an amble light should have the same walk delay as pressing during a green light.
If you don't press it, then it has to be part of a cycle. When you are in that cycle (or in that range using a single timer, see my first video), you introduce additional output(s) for the walk signal.
Thank you for such excellent videos! I have one question, if you do not mind. Do you have any reason (apart of "habit") to not use Sequential Flow Diagram? I am not professional PLC programmer - I am Java programmer. I found programs written in Ladder Logic, Instruction List and Structured Text languages difficult to conceive ... and even more difficult to write from a scratch. But I have no such "mentality loop" with SFC programs.
If you haven't ever done boolean algebra and logic gates it should be difficult for you to understand how actually computers work. Programming in Java or C# isn't so difficult, because they're languages that you've to learn and even children can do it, as I was programming in BASIC as a kid without actually knowing how the machine understands my language. PLC programming is a completely different subject, it's mostly based on logic gates and on/off states as computers use 1 and 0. To become a real PLC programmer you need to study Boolean logic first of all.
@@PLCprogrammer at 10:31 you show the top part of rung 11 - but is it me or is it incorrect in that it ought to be B3:0/3 as the XIO instead of B3:0/1 ? All in all a great video!
