you already got the answers needed. but I think it will be worth to explain the bit shift function. when you do shift a bit, the most left bit goes to the void. it does not continue shifting all the bits in the memory address infinitely, so using an MB and a bit shift of 1 was essentially shifting 1 bit 1 place, if it was 1 then it would become 0 because the 1 was thrown into the void all the following MBS are unchanged because you only shifted the first Bit. shifting by 8 is taking 8 bits and shifting all of those, effectively displacing 1 position on a vector of 8 bits. -
If you want to turn them all off at once, use Vector Fill: -
Hello @brugola The RED solid LED ndicates that there is no power provided to the module. This explains nothing works. @Cara Bereck Levy, can you please add this information to the help? Have a good day! Rivka -
Good evening Ausman, I would like you to analyze it and say what you think, I did it this way In the first pulse, set 1 to MB16 and from then on it goes up to mb10. my problem will be to turn off the engines after pressing the off button And then it works well for my project -
I thank everyone for contributing their knowledge and suggestions to this topic. One question, Unilogic has a Scope Tracer function to monitor the behavior of some tag (well, I use it that way hehe), in this case I have used it to monitor CPU usage, here is an image about it (Image 1 ), I would like to know if this CPU tag corresponds to the consumption by the HMI or the PLC as such, I have also used this tool to determine which processes consume the most CPU resources, among my conclusions is that performing "automatic" storage " by ladder and the "DTI to File" block consumes too many resources if it is used automatically every 5 seconds, with this I have also tested the screens, when making all these changes the performance in terms of changing screens is noticeable, It could be considered a good practices manual (or well that's what I call it haha), it is worth clarifying, previously with the image that I shared with you, before this the CPU consumption was through the roof, I am also sharing an image of it with you . (Image 2). Please don't forget my question haha, I appreciate it very much. Imagen 1. Imagen 2.
