  1. Connect FX3G-40M to proface HMI GP-4301TM

    Hi kdshaw87, The PLC 8-pin front port (MiniDIN 8) is RS-422 (4-wire), not RS-232. Appearently your HMI is set for RS-232, what seems incorrect. Another important point is the protocol. Does Proface driver for Mitsubishi mentions which protocol it does use? The PLC front port only accepts programming protocol, not MC Protocol in any format. The front port is "CH0" so, the serial port parameters you sent does not apply to front port, only to extension ports, what is not your case. Regards!

    Simone, Ciao! Could you please, send your project here or to me by email? Saluti!
  3. Hello RedViper, According to your description, it looks OK the procedure you did. To ensure that the program was correctly loaded in the PLC, you may open GX Developer, go to "Online" > "Read from PLC" and try to read the program again. The best way to check if the program is really running accordingly is to monitor the program that is in PLC memory. I checked your program and, apparently, you have 2 units 1PG installed, in positions K0 and K1. As I could realize from the program, 1PG modules are working in "Interrupt Single Speed Position Mode". In this mode, the servo movement is started by bit 9 of BFM #25, in speed mode first. I could detect that your program uses bits M9 and M209 respectively for modules K0 and K1, for starting the servomotor movement. These bits seem to be turned ON by interruptions: in the case of M9, interruptions I10 and I20. These interruptions are triggered by two high-speed counter comparison instructions HSCS, connected to counters C235 and C236. Long story short, my recommendation: 1- First things first: I know it may be obvious but make sure your PLC is really running (RUN LED is solid lit). Sometimes we neglect the simplest thing and this may be the problem. Check also if 1PG module is not in error (ERR LED in 1PG module is not lit). If 1PG is in error, you must check BFM #29 and see what is the error. Follow the potential error causes; 2- Monitor counters C235 and C236 while the encoders (which may be mechanically linked to the conveyors you mentioned, check it!) shafts are spun. If those counters are incrementing while the conveyors run, it is a good sign; if it is not incrementing, you will want to start looking at what may be wrong with those encoders, including if X0 and X1 (encoder inputs for C235 and C236) inputs are blinking when spinning the encoders slowly; 3- If it is all OK with the encoders, look at HSCS instructions, if the HSCS setpoint registers (such as D316 in your program) have correct values for triggering the interrupts (the value must be one that the C235 may reach and trigger the interrupt); 4- If the HSCS setpoint (such as D316) is good for the C235 to reach it, and C235 is actually passing through it, so interruptions are probably being triggered. Check if D302 has a value different from zero. It is the pulse train speed to be sent to servo drive; Important to have the manuals to follow the steps above: FX2N CPU Programming Manual:  FX2N-1PG manual: Regards!
  4. Alarm display (System) with GT Desiger3

          Simone,       The system alarm on GT25-V will work just like GT27, the same way I explained in the video. If you still cannot see the current alarm in "System Alarm Display" when you add it to some screen, maybe it is missing to enable "Use System Alarm" on "System Alarm Observation", as in the picture attached to this message. It is a kind of a service that runs in the background capturing system occurrences.       Is there any specific system alarm that you are trying to catch on the screen and it is not working? If so, please let me know! Maybe I've passed through the same situation before.       Saluti!
  5. Alarm display (System) with GT Desiger3

    Hello Simone, I made a quick video about this subject, please check it out. It may help you! Don't hesitate to contact me if you have any further questions that I may help. Best Regards!
  6. S7-300 to GOT Simple

    As further as I know, DB inside data cannot be accessed by GOT Simple but I will check further with my colleagues to see if anyone found a way to do it easier than transfer data to/from %M type devices in S7-300 PLC and let you know! Best Regards!
  7. Alarm display (System) with GT Desiger3

    Usually, we create one alarm configuration and for displaying on the screen, we choose "history alarm" or "alarm display". Does it work for you? Do you need history and current alarm only for system alarms? If the above works for you, I can send you some print screens about how to do it! Best Regards!

    The FX3 programming port unfortunately has a proprietary protocol. The documentation is not disclosed by Mitsubishi Electric.
  9. About Fx3u-64ccl and how to config using two FX3U cpu's

         Vinícius,       Just adding a comment to Crossbow reply, currently 110 Ohms cable type is more common. I don't know if you already purchased the cable but, just in case, in Brazil you can find CC-Link compatible cable from Igus (Jundiaí) and Eurocabos.       If you need help in Portuguese, Mitsubishi Electric Brazil has a technical support address where you can send your doubts.        BR,        Thiago  
  10. GOT2000 Blinking lamp with signal off

        Bloggy,     You can make a lamp to blink by setting the option below. Click in the figure of the ON lamp and the configuration, shown below in green rectangle, will appear. You can select from slow (low) to fast (high) blinking.   BR, Thiago
  11. PID Loop Review

         Dear wbaumgartner,      I took a quick look and your program looks OK for me, as program structure. I ran it under simulator to check if any errors would appear (and, believe me, if you do something inconsistent for these QPLC PID instructions, you will sure get 4100 coded operation error) and no errors (I don't know if you tried to run your program under it, and more recently the GXW2 simulator is supporting PIDINIT/PIDCONT instructions).      As you may know, PID is very process-dependent control so it is difficult to really know if it will work but all-in-all it the program looks fine.      BR,      Thiago
  12. Mitsubishi PLC comparison function

    It's ANDed, so any of the conditions in your ladder line goes false, M3 goes false, as well. Regards!
  13. Mitsbishi FXxx Programmer-Port. via C# or VB

    I know it's not exactly what you're looking for but I recommend you add a FX3G-485BD and use computer link protocol that is open documented (like "MC Protocol C type, for serial"). I can send a link to you of this manual if you decide to use this option, just let me know.  Regards!
  14. Mitsbishi FXxx Programmer-Port. via C# or VB

    Sorry Bob, I can't help. This port only works with programming protocol which is Mitsubishi proprietary. Probably there's a specific protocol command to set baud rate in first communication cycle... I don't know! I don't have access or clearance to such as this information. Even D8118 and D8119 is undocumented in public manuals.

    Are you getting some alarm or problem?
