  1. Connecting to Multiple HMI-GP Pro

    It is interlock signal. I prefer HMI than wiring
  2. 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)
  3. 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
  4. 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.
  5. How to adjust the resolution of a timer on FB

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

    I use FX3U PLC.
  7. 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.
  8. Improve the accuracy of RPM measurement.

    This is code I wrote to do that code.txt
  9. 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.
  10. 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?  
  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. 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.
  13. 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.
  14. Compare two PLC programs in GX Work2

    Thanks @sczotI got it.
