  1. CP1L-EM30 - Analog inputs built in on board

    Have you either set DIPSWITCH 4 or 5 ON for position of Analog module OR Configured module setup in PLC settings? See section 10-3-2 in manual W516-E1-04 Link here:-
  2. CX-One AUTO UPDATE topic

    We have a 3 User License for CX-One V2.01 only one license is installed on laptop. Ran an auto update yesterday on the laptop which upgraded the following:- CX-Programmer from V7.1 to V 7.2 CX-Designer from V2.0 to V2.1 Performed NEW installation on desktop and ran auto-updater for all available updates. Installed all new files just fine BUT it only gets as far as CX-Programmer V7.1 and CX-Designer V2.0. We now have two PC's with different versions. How do we update the desktop??? Is there some kind of delay [wait an hour, a day, a week???] before the auto update "searches" for the next latest version? Have tried restarting computer but still no success!! The auto update website show a message:- Auto-update service for CX-One newest version is available from 22 August 2007 16:00 GMT. Sorry for putting the inconvenience. but does not appear to have installed it OR found the latest upgrades!!! This is a real PITA. One computer ugrades just fine and the other does NOT!!! Any suggestion as to what the problem may be???
  3. Learn CX-Programmer

    Manuals here:- Youtube videos:- OMRON Downloads on this site:-  
  4. About Function Block Variables

    All explained in manuals and quickstart guides.
  5. Sysmac Cj2m Cpu35

    The red error lights on the CPU and some of the I/O modules indicate that SIOU refreshing is not being accomplished. Have you made any changes to the PLC settings? Do you have a copy of the program? Do any of the units have check marks [see attached picture]? This error occurs if SIOU refresh has been disabled in the PLC settings and the program logic fails to perform an SIOU refresh for more than 11 seconds.  
  6. Suggest you review the STEP/SNXT instructions for your program. What model PLC are you using?
  7. Indeed the CJ1M is old and the the CJ2 series is the current PLC offering. I use around 30 CJ2 series PLC's/Year on multiple projects with CX Programmer. The NX/NJ series Machine Automation Controllers with Sysmac Studio are the latest product offering, but I am not aware that OMRON PLC products with CX Programmer are being phased out or at end of life cycle. Unless you know something I don't??
  8. Capture snapshot of I/O data for simulation

    Yes I agree. IMHO turning on/off I/O manually is BEST approach. Just trying offer a possible solution.
  9. Capture snapshot of I/O data for simulation

    Add code to running PLC using the XFER instruction to copy the CIO areas you wish to keep to unused DM location. Save the D memory to file. In simulation mode add a oneshot instruction to XFER the saved D memory back to CIO.
  10. CPU load memory

    Select "View" and in pulldown "Memory_View".
  11. Task control? scan priority

    Set the Task Properties as a Cyclic task but with Operation start unchecked. Then only call the task from your main program with a oneshot [rising edge bit] to trigger a TKON instruction. At the very last rung of the called task place use LD CF113 [always on] followed by a TKOF. Task will only run once when called from main program. Picture shows Cyclic Task 01 with Operation Start unchecked.  
  12. mx2 control with modbus

    Congrats mate! You didn't give up. Can you enlighten us how you got it working after initial problems?
  13. Controlling mx2 inverter without modbus

    Always good to get updates from forum posters. Keep plugging away and good luck mate!
  14. Controlling mx2 inverter without modbus

    Don't give up so quick. One of these [or similar product] would easily solve your problem.
  15. Controlling mx2 inverter without modbus

    Looking at the RP input in the MX2 schematic it would appear that it only accepts a Sinking input signal. To work with a CP1L-EL it must have Sinking Transistor outputs i.e. CL1L-EM**DT-D Providing you have a Sinking Transistor model, you have wiring correct between PLC output and MX2 and high speed output is pulsing you should be able to monitor this signal on the MX2.  
  16. Controlling mx2 inverter without modbus

    Those instructions are typicallu used for positioing. If you are just controlling speed use a combination of Continuous Mode [Speed Control] instructions SPED, ACC and INI. See Section 7-2-4 in manual W516. Pin RP = Pulse input on MX2
  17. Controlling mx2 inverter without modbus

    Use standard outputs from the PLC for Start/Stop/Reverse signals to the MX2. Use a High speed pulse train output from the PLC to the RP Pulse Input on the MX2 to control speed.
  18. CX Programmer Problem. Willing to pay via money transfer!!

    St Patrick's Day and copious amounts of Guinness must have fuddled your brain! Sober up and try working it out for yourself. We are here to help those that help themselves. OTHERWISE send me $25 per step of code. Approx $25K total and I'll do it for you!!
  19. Using PTO's to control multiple stepper motors?

    AND read this article. Though written for a CJ1M the principles are similar to your model.
  20. Trouble connecting from PC to CP1H-XA

  21. Limit

    This isn't an AB test of how they DO THINGS. Rather OMRON has a unique [yet different approach]. IMHO much easier to use. For example:- A simple oneshot up differentiation condition requires NO stupid extra bits to manage, just a change in the examination of the bit with an upward symbol. See here:-
  22. D memory data not moving into instructions

    Try setting the PLC properties to "Execute_Timer/Counter as Binary". You must first send new settings to PLC and then perform power cycle.
  23. D memory data not moving into instructions

    Hint!! If you need to initialize D memory values at power up it is much simpler to define a TASK that runs once on first scan to write necessary values to D memory. So each time PLC is powered up the required values are initialized. Create a new task named FIRST_SCAN. I would suggest Cyclic Task 00 (Startup). The last instruction of this task should use the always ON flag CF113 followed by TKOF 0. Everything in this task will then be written to desired memory only once. So stop messing with LCD board and use tasks to initiate values you need in your program.
  24. D memory data not moving into instructions

    Are you bothering to read the manual?   CP1W-DAM01 Pages from W462.pdf
