  1. Timer won't reset

    Figured it out. Seems one can not have the timer in the IF sentence. Moved it below END_IF and it worked.
  2. Hi! Does anyone know why my TON timer won't reset? When In goes false, ET does not reset itself.. The controller is a NX1P2-9024DT1   From the manual: The TON instruction outputs TRUE when the set time elapses after the timer starts. The time is set in nanoseconds. The timer starts when timer input In changes to TRUE. Elapsed time ET is incremented as time elapses. When ET reaches set time PT, timer output Q changes to TRUE. ET is not incremented after that. The timer is reset when In changes to FALSE. ET changes to 0 and Q changes to FALSE. If the timer is started and then In changes to FALSE before ET reaches PT, the timer is reset.
  3. Yes that did the trick for the 24hr format, thank you! It worked with the UseCustomDateTimePattern with HH:mm:ss. We also used MM/dd/yy for the date. As for the keypad, we are using the same type as the one that was discussed in that link. We'll see if we'll spend any more time on it, or just let be for now.
  4. I think i have figured out question nr 2. But the clock view is still a mystery.. Any tips on showing it as 24h?   And a new question, we want to set a time on the hmi, and we've found a ''DateTimeKeypad'' pop-up that is the right data type, time of day. But we don't like that its a roll-down menu, we would rather have a keypad with the numbers. Any tips on how to change this?   I see i have'nt written earlier that this is for a school project that's due in 1 week, so any and all help is much appreciated! We're not so experienced in sysmac yet..
  5. Thank you for answering me, sir. I have some new questions too! 1. The clock on the HMI is showing AM/PM, how can i display it as 24h? 2. I have a temperature sensor input, and a set temperature i want the room to stay in. Is there a way to program a differential(hysterese?) value? F.ex. if the measured temp is 15, and set temp is 18, the oven will turn on until measured temp is 18, and go off. But then when it falls to 17,9 it will turn on again. Maybe if there is a way to set a differential to 2 degrees, so it wont turn on until measured temp is 16. And the output/oven wont go on/off all the time. Maybe differentiate the rising and falling measured value?  
  6. Hi! I want to use the real time of day to set the outputs on and off. Example at 6am the output goes on, and at 3pm it goes off Can it be written i ST? Any help is much appreciated!  
  7. Yes its an NA5, have seen in one omron guide now that they offer an app for iPads that's for remote viewing of the HMI. We're not going to use an iPad so we'll have to figure out a way to do this on a PC. Its a NX1P2 PLC
  8. Hi, Is it possible to mirror the HMI to a window or a program which we could run on a computer? We are thinking about using a VPN so we have the possibility to control the PLC from a different location.   And i'm also wondering if its possible to code javascript, PHP or similar in the PLC? We are thinking about getting the weather forecasts to help control the heater ovens in some industrial halls.     This is for a school project Thanks
  9. NS8 PT connecting problem

    The dip switch nr.5 was set OFF, and when setting it to ON, it worked. Using a Option Board if that has any influence Thanks for the help.
  10. NS8 PT connecting problem

    Hi, im trying to connect a NS8 with a CJ2M thru serial port, and after downloading both programs to PT and PLC, the screen is just showing ''connecting''. What could be wrong? See attached files for communication setups
