  1. Connecting to a OMRON PLC

    For Heaven's sake buy the correct cable for programming via the peripheral port. Don't even waste your time trying to make it. P/N is CS1W-CN226. Just google it and there are many resources to purchase the cable at reasonable cost. If your computer doesn't have a Serial Port then you will also need a USB to Serial converter. This model has never failed me with CJ1M PLC's. http://www.serialcomm.com/USB_adapters/USB_converters/usb_to_rs232_adapter/usb_to_rs232_adapter.product_general_info.aspx
  2. If you decide to use a CJ2M with an added MD21* for your motion application then this article in the downloads sections is very useful. Though written for a CJ1M it is still applicable to the CJ2M.

  3. Puls train.

    Your gonna spend a ton of bucks on the NC213 module vs. upgrading to the latest CJ2M CPU with CJ2M-MD21* Pulse I/O module. Mt 2 Cents.
  4. Relay Digital signals

    The CJ1M is an old unit. Replacing it with CJ2M-CPU and one or two CJ2M-MD21* Pulse IO Modules is a far better option for High-Speed counters and Pulse control outputs. IMHO you are going to waste a ton of time messing with the CJ1M for your application. My 2 Cents.
  5. CX-Programmer Unable to Open File

    If the porgram was created in your version 9.50 or earlier then an update probably won't fix your problem. First try a full auto update and see if that fixes your issue. Failing that a complete uninstall followed by Clean CXOne, then a complete reinstall and a complete auto update is probably your only solution. Very tedious and time consuming but as a last resort should ultimately fix your problem.
  6. CX-Programmer Unable to Open File

    Opens fine for me in CX-Programmer V9.65
  7. How to retain value in timer (TIML) on power off

    It's in the PLC instruction manual. Increment ++/++L Decrement --/--L Remember to use a rising edge LD instuction ahead of the Decrement instruction.
  8. APR AND SCL instruction problem

    The CP1E N20 will NOT handle any analog signals or expansion models. The CP1E NA20 does have TWO analog adjuster inputs built-in.
  9. APR AND SCL instruction problem

    My personal preference is to use the APR instruction vs. SCL. http://forums.mrplc.com/index.php?/topic/30950-proble-with-scale-function-in-cp1l/#comment-145675
  10. Count how many words are being used

    Personally prefer to use IR pointer vs SRCH (181). Faster scan time, Attached is update program. Note that D0 to D2000 is 2001 loops.   Count result of data memory >0 is in D2100   Word Search Greater than D0-D2000.cxpWord Search Greater than D0-D2000.cxpWord Search Greater than D0-D2000.cxps.  
  11. Count how many words are being used

    Use a FOR/NEXT loop with Index Register. See attached example:- At rising edge of W0. Searches 10 words D0-D9 for value greater than 0. Place result in D100. Word Search Greater than 0.cxp
  12. CP 1E NA ANALOG INPUT PROBLEM

    Have you configured the PLC settings correctly AND ternsferred them to the PLC AND performed a power cycle. Analog input data for AD CH0 should appear in CIO 90.
  13. Just tried opening Sysmac Studio for a new project and I get this message. Any ideas how to work around this issue. VERY FRUSTRATING!    
  14. Wipe memory from PLC

    Yes that works, but in my opinion much cleaner to have all memory areas cleared when starting a new project.
  15. Auto Assign Addresses To Symbols?

    NOT AUTOMATICALLY that I know of. The method I use is to copy desired addresses from CX Programmer Symbols and paste into EXCEL. Edit EXCEL spreadsheet to add/change desired name then paste back into CX Programmer. A few words of caution:- There is some conflict with WORD and BIT addresses you need to be aware of. For example CIO Word 0 and CIO Bit 0.0 will both appear as 0 in your spreasheet.
