  1. 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.
  2. 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.
  3. CPU load memory

    Select "View" and in pulldown "Memory_View".
  4. 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.  
  5. mx2 control with modbus

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

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

    Don't give up so quick. One of these [or similar product] would easily solve your problem. https://www.asi-ez.com/member/~XNPNPNP.asp?
  8. 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.  
  9. 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
  10. 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.
  11. 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!!
  12. Using PTO's to control multiple stepper motors?

    AND read this article. Though written for a CJ1M the principles are similar to your model. http://forums.mrplc.com/index.php?/files/file/268-cj1m-motion-and-interupts-quickstart/
  13. Trouble connecting from PC to CP1H-XA

    DIPSWITCHES ON SW4 or SW5??
  14. 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:- http://www.plctalk.net/qanda/showthread.php?p=620324#post620324
  15. 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.
