  1. Map Physical Input and Output to Word

    You have to make a union.    See below: First, make a union under data types like this: Then create a variable that is of the type that you created: Then use the variable as both a bit and a word like this: You can ignore my comments about VB in the ladder, this was an example that I did for someone else. 
  2. Lamp Bit and Buzzer

    Good point ... I did not look closely at the processor.  
  3. Lamp Bit and Buzzer

    What was not stated in the example above (Basics box checked and $SB area allocated to D0) is that you would then turn on D0.12 (when turning on W10.06) in the PLC ladder in order to turn on the continuous buzzer.

    I would suggest that you post this in the AB forum.  The PLC is only responding to commands that it receives from the HMI.  This seems to be an issue with the PanelView.
  5. Up And Down Counter In Omron PLC CP1E

    You can use increment and decrement instructions like this:
  6. Why not just go to View -> Variable manager.  Find the local variable in the program and then right click on it and move it to global.
  7. NT Transfer Utility for NT31

    @EnglishDan are you perhaps referring to the Conversion Utility that will convert an NT program to an NS program?
  8. Change an Integer. Really simple for you guys

    To expand on that slightly, the ID number is used when using a handheld programming device (pendant) rather than using the software.  The programmer would press the FUN (function) key and then enter 325 and this instruction would be entered.
  9. Omron HMI NT20 Software

    If you have lost the program and do not have a saved copy, then it is gone.  Your only option is to try to get a copy from the original machine builder or to re-create your screens.  If you are just trying to upload or download your screen program and are trying to get to the system screen to put the HMI in transmit mode, touch any two corners of the display at the same time and the system menu will appear.
  10. I would set up a loop and a calculation unit to get this done.  This is the core of what I would do (showing averaging the area from a Gravity and Area tool): The conditional branch would do this: Note that the unit that would look for the end marker would be between 1 and 4 and is not shown.  Unit 4 would decide based upon this inspection whether to go back to 1 or continue on.  Also note that you may want to build a counter into the loop so that it does not get into an infinite looping situation.  This may require another conditional branch instruction prior to Unit 4 that says something like, if the number of samples exceeds 200 (or whatever is appropriate) don't keep looping.   The calculation unit does this: Unit 0 initializes the total area and number of samples and is only performed the first time that the inspection is run after switching to this scene: Hopefully I have conveyed enough information for you to understand what I am proposing here.  I have left out much of the code that would be required to do this, but have demonstrated the pieces that you are missing.  Let me know if this answers your question. 
  11. Help with structures

    Oh, I misunderstood.  I thought the question was, "Is there a way to map local variables to the HMI?"  My apologies.  Yes, as long as the variable that uses the structure data type is global, it can indeed be mapped to the HMI.  My apologies.
  12. Help with structures

    No, there is not a way to do this.  To map a variable to the NA, the variable needs to be global (or a system variable).  
  13. Cannot Connect to CP1L-E

    Ah, yes, you are right....
  14. Cannot Connect to CP1L-E

    The CP1L-E only has ethernet.  
  15. NJ301-1200 -Servo Connection -EtherCAT

    Can you share which settings needed to be made so that others might not have to go through this?  A good rule of thumb might be to start with default settings and work from there.....
