Update: If you set the "Element behavior" property of the switches to "Image tapper" instead of "Image toggler", then they behave as a momentary switch.
Hello, button a tap can't define variables. Although I select PLC_PRG.start, plc outputs do not change when the button is pressed. Do I need to add a library or where is the error? codesys version 2.3
Sir, in visualisation toolbox that Lamps/Switches/bitmap section no images are there, i can onky see the labels. Also when iam dragging the thing to the screen, no images are loading there on the screen
I have a whole set of screen buttons in my HMI and I want to change color on tap on each of them to give touch feedback to the operator. Problem: If I use one variable BOOL for Tap -> Variable for all the buttons, if I tap on any button the rest of them also change the color. It does not make sense and I don't want to create separate variables for each of the buttons in the interface.
Hello, thanks for video, but I have a question when I will create the momentary switches doe's it mean that I don't need to use the R_TRIG in such case?
Hi Stanislavas, That is true! Indeed when you use the momentary switch, you do not need to use the R_TRIG, since the state of the variable associated with the switch will change for one program cycle only.
If the buttons refer to different variables, then normally you should be able to activate and deactivate the buttons independently, unless the logic prevents this situation. For example, it does not make sense to activate both Start and Stop buttons at the same time. I hope I answered your question.
HI , if i want to START & STOP operation from same Button & it the button should change its color. ex :- if Start then Green & if Stop Red. How can i do that can you let me know.

Thanks for all your video It is very great with me when i am starting program with codesys so your video is the best for me understand about codesys !
Thanks a lot for your nice comment. I am glad that you have found my videos useful.
Great vid. I am learning a lot from your vids thank you.
Great to hear this. Thanks for your nice comment!
Great video! Thank you🙏

Hi,
You don't need a library to have the button working normally. I am not sure about the reason for your issue. Did you manage to fix it?

Probably you need to install CODESYS again.

can i activate one button, without deactivating the second one?

You can use the "Color variables" in the properties of the button. I will try to address this in one of my upcoming videos.
How can i write this code in ST ? :)
It is quite simple:
Motor := (Start OR Motor) AND Stop;

Thank you ! I've solved the problem :)
Nice to hear that you have solved it!
