  1. Or I think this way it might work. I am posting the picture of ladder and ladder quick view. Am I correct?
  2. Thank you for explanation. I think my last display will not be loaded with this logic because MB 1685 bill be RESET before my LD LAST element will be active. Will it help if I put my RESET coil in next net? Because it is important that my LD LAST gets active before MB1685 gets RESET. Will next ladder logic help? (I need to have a direct contact before LD LAST element).
  3. So I am looking at this, but I am not sure what I am looking at, can you explain a bit how I can see from this the sequence of this net.
  4. Hello, I have a question about ladder running sequence (what happens first). To be more specific I posted a picture of ladder program. As you can see i have a MB1685 (direct contact and reset coil). I want to know if my program will be able to LOAD LAST DISPLAY (MB1685 needs to stay ON and SB16 is active), before MB1685 will get RESET (so OFF). I wonder what will happen first and if this logic will work (so that it will load my last display). Please if you have an answer reply to me, because I can't test it myself on PLC (I don't have one available). Thank you!
  5. Hello, I am making a machine, where, for safety porpuses I need to PAUSE the program. My machine has a Pressure reducing valve and some solenoid valves. If my pressure sensor senses that pressure is too high (my Pressure reducing valve doesn't work correctly for example) I just want to pause my program so it doesn't open any solenoid valve and let that high pressure into my machine. So is it possible to pause a program untill pressure is too high? Including pausing Timers so they wouldn't count. Program is written in Visilogic. Thank you, Jan
  6. Thank you for your help and time 😄. I will use that and correct my program tomorrow.
  7. Okey thank you I will try that I need 1 decimal place but it is good to know. One more question on this topic. Lets say I want my machine to hold 2,5 bar in sistem. I will need to store that number in my MI. I would like the user to write value - 2,5 (like in real life) with keyboard, and not 25. Are parameters in my 'numeric box' correct?
  8. Thank you for reply. Well I am using Pressure transmitters 4-20mA on 10-bit (Analog inputs). First I linearize them (X and Y). My sensor can read from 0-2,5 [bar]. I can't write constant 2,5 in Y2. So that is why i wrote 25 and then I use math function DIV (calculates MI2/10[constant]) and i get for example 2,5 or any other value. Or can I display for example 25 as 2,5 in my 'numeric box' on HMI? Never tried that. Jan
  9. Hello, I am new to this forum. I am making a project where I am measuring pressure values inside 10 water tanks. So I am measuring 10 MF vaules. On the screen I can select a water tank, which pressure I want to view. After the selection, that takes me to next HMI screen (I would like to keep only one Display/screen on HMI) where I will view pressure in this tank. I would like it to show me only the pressure in that specific tank that I have selected previously. So on my HMI I would like to insert only one 'Numeric' ''box'' (where I can view MI or MF,...), but only the MF or MI of that t
