  1. Helllo everyone I need to connect multiple HMI-GP Pro (each HMI control different PLC) via ethernet. May anyone show me how to set up the connection, please.
  2. Connecting to Multiple HMI-GP Pro

    It is interlock signal. I prefer HMI than wiring
  3. Connecting to Multiple HMI-GP Pro

    HMI observes some signal of PLC which it controls. Then I will use D-Script function to inform for another HMI (if they can communicate via ethernet)
  4. Connecting to Multiple HMI-GP Pro

    I'm sorry for post it in Omron. I can connect PLC with HMI via ethernet. But I alos want to  connect those HMI via ethernet (not master -slave relation) so that I can transfer value from PLC to PLC. I search in GP Pro manual, but there are only 2 method: connect one PLC to multiple HMI or connect one HMI to multiple PLC
  5. Hello everyone, I'm looking to use a timer with a 10ms interval in a function block. However, I'm unsure about how to create it, as all the timers I've declared so far are set to 100ms. Could someone please provide assistance? Thank you.
  6. How to adjust the resolution of a timer on FB

    Thanks, but I want to create a TIMER_VAR not a fix address timer.
  7. How to adjust the resolution of a timer on FB

    I use FX3U PLC.
  8. Improve the accuracy of RPM measurement.

    This is code I wrote to do that code.txt
  9. Hello all. I have a problem with RPM measurement for a spindle. I hope someone can help me. My company's machine uses a disk with two pinholes to measure the speed.In the current program, it uses the following instruction to measure the speed:  SPD X0 K3000 D1 The issue is that we only receive 2 pulses per revolution, which requires using a longer sampling time for accurate results. Unfortunately, this leads to a delay in the response time. I am considering trying a different method for measurement. Would using a PID controller be a good idea?  
  10. Improve the accuracy of RPM measurement.

    I intend to use it to optimize the sampling time in order to ensure both response time and accuracy.
  11. I still don't understand the role of the "number of pulses" parameter in position control mode. Why is it necessary when the distance varies depending on the position deviation? In Mr Configurator 2 software, the value of the "number of pulses" parameter is fixed and determined by the value of the electronic gear.
  12. Hello all,  I don't understand therelationship between of Number of command input pulse and  pulse train in positon control mode of Mitsubishi servo. May anyone explain for me.
  13. So, number of command input pulses does not affect to speed, does it? Do you know what affect to speed of servo in position control mode. I read the manual, but it doesn't  mention about it.
  14. Dear all I have an Omron NB  pkg file of  China machines. But I can decompile it, I guess it due to the China font is not supported anymore in my current software NB designer. I'm so appreciate if anyone can help me to decompile it. https://1drv.ms/u/s!AjZ-DZZV347AgeIP6hsZ3fEijAp99g
  15. Compare two PLC programs in GX Work2

    Thanks @sczotI got it.
  16. Hello everyone, When using compare function in GX Works to search the different between two programs, in the result window I must scroll the mouse to see the difference. Is there another way to see the diffrence fast and exactly.  
  17. Hello everyone, I'm changing a PLC program from using Q173D into QD77MS. In Q173D, I have a SFC program which uses M codes in 3 point positions. It means after positioning one point, the M code output signal need to be changed from OFF-ON -OFF to jump to the next positon, I want to keep this feature in QD77MS with continous path positioning mode. But I don't  know how to do it. With continous path positioning mode, if I keep M code output signal on, after  positioning one point complete, it will still jump to next point positioning. May any one help me,please
  18. Continous path positioning with M code in QD77MS

    Thanks @AndreasW, I can't use  positioning complete mode because I need the speed keep constant (not return 0 after singgle point positioning completes). Because in Q173D, the speed doesn't return 0  single point positioning completes if I turn on and off the FIN signal soon enough so I want to keep this feature in QD77MS.   
  19. Timer IC

    Hello all I am sorry for posting this question in the forum, because I don't know where is suitable for posting it. I need an IC that is small, and can set timer in it. I means after setting a timer in it from a trigger, when timer on it will output in pin. Do you know which IC  have that ability. Thanks so much.
  20. Timer IC

    I can't set a timer in 555 IC without adding a new circuit. I want an IC which already has a timer.
  21. Using many controllers in MotoSim

    Hello all, Is there any one know how to simulate many controllers at same time  in MotoSIM EG-VRC of Yaskawa. Thanks in advance
  22. Hello every one  I got a trouble with Omron Servo, when I write instruction MC_Move Absolute in sysmac studio . an error appear to say "negative limit input was on". Do you know what is "negative limit input" and how I can find it. Thank you
  23. Thanks @Joe E., I finally found it. It is exactly what you wrote. https://www.youtube.com/watch?v=Cf64oco88S8&list=PL7BAkmD1dytiKRUTJTYTGD_uQX7UpbzdW&index=4
  24. Hello, I would be really thankful if someone could help me . Recently, I start using Allen Bradley PLC and HMI.  Before, I used most of . I have difficulty in seeking some similar Mitsubishi functions  in Allen Bradley. - First, I don't know how to switch HMI screen by using instruction in Allen Bradley PLC.In Mitsubishi PLC, I can do that by move a number to base screen register D0. But I can't find the similar register/tag in Allen Bradley. - Second, I don't know which bit, relay, timer, counter, register will latch it's value when power turn off. In Mitsubishi, I can know that by looking at FX parameter. May anyone give me favour, thanks.
