  1. FX3U-ENET-ADP how to connect and read strings?

    From: FX3U-ENET-ADP User's Manual - Up to 4 connections can be established and used at the same time in the Ethernet adapter.    
  2. SAIA PLC - Modbus TCP truncates 32 bit value

    Right, I thought you might have created some since your post. Check you PM, I sent a small program.
  3. SAIA PLC - Modbus TCP truncates 32 bit value

    Interesting. What about the byte order? The next day. Years ago I wrote some routines to covert to/from FFP - 754. I went and looked at the code and while it has some bit shifting it is not only shifting. For example the exponent is biased differently. If you have some working code that converts both directions, is only shifting and maybe an and/or or two, I would really like to see and test the code.  
  4. SAIA PLC - Modbus TCP truncates 32 bit value

    IIRC, the PLC provides routines to convert from/to SAIA native Motorola FFP and IEEE 754.
  5. SAIA PLC - Modbus TCP truncates 32 bit value

    Hello, Or perhaps you could use a program, like PeakHMI, that can access the SAIA PLC using native SAIA protocol. FYI, SAIA uses the "Motorola Fast Floating Point", FFP for floats.
  6. QJ71E71 UDP Communication Protocol

    Very good. I suspect the port number was OK, you can test it. Setting up the send and receive fixed buffer.
  7. QJ71E71 UDP Communication Protocol

    Using PeakHMI or your code?  
  8. QJ71E71 UDP Communication Protocol

    I looked at the settings for an FX project. Here is a screen capture.  
  9. QJ71E71 UDP Communication Protocol

    Zip up the GXWorks project and post it here or PM me
  10. QJ71E71 UDP Communication Protocol

    Hello, There is configuration that is required. See my first response in this thread: https://forums.mrplc.com/index.php?/topic/41731-fx3ge-communication-with-kepserverex-via-udp-protocol/#comment-190141 It might help.
  11.   I had the same results, 4003 bytes.  
  12. His original post had MODBUS and the point about using Wireshark is 100% spot on.
  13. Hi, PeakHMI could work for you.
  14. HOSTLink read multiple DMs

    I read the manual portion (MULTIPLE MEMORY AREA READ) and yes that does what you want if your PLC supports "C" series commands. Nice find.
  15. Extracting Digits of a Number

    You could convert to string and process each character to a number. Or  you could divide by 10,  multiple the remainder by 10. Then subtract the remainder from the divide result and repeat the above line until a single digit remains.  
  16. PLC & HMI communication

    In this instance, "Finger pointing" is when X points at Y and says it is not our problem it is Y's problem and Y points at X and says it is X's problem and you are in the middle, possibly with no assistance from either. Finger-pointing: a situation in which someone is blamed for something that goes wrong
  17. FX3GE communication with KEPServerEX via UDP protocol

    Of course I would say "Switch to PeakHMI", it has OPC DA server included. As to Kepware, I have only looked at the trail versions and each time it worked as expected.  I have not trialed Kepware with FX3.
  18. FX3GE communication with KEPServerEX via UDP protocol

    You can download the trial version of PeakHMI and try the FX3 UDP port for verification. I do recall configuring the controller for UDP was interesting. Something like this:
  19. Comunication

    Using online translation he wrote: are you having problems with the extended module of PLC fx3u 32 MR-ES.? Specifically, what. X0-X7 sequence. X10-X17. The X20-X27, Y0-Y27 is right?   Me: Is your 485 terminated properly? I ask because you have not provided much information on the problem. Error codes? How is it wired? Tried another expansion module? Does the 485 bus work with any device? etc.    
  20. Comunicação

    And if English is not a language for you, you can use a free online translator. Create the message in Portuguese, use a translator, and paste the result here. I used Bing's translator for this message. E se o inglês não é um idioma para você, você pode usar um tradutor online gratuito. Crie a mensagem em português, use um tradutor e cole o resultado aqui. Usei o tradutor do Bing para esta mensagem.
  21. Reading inputs using FINS/TCP from a PC

    Hello, Download the trial/demo version of PeakHMI and use it for generating request to the PLC. Use WireShark to capture and analyze the request/response packets.
  22. Negative sign in HMI

    Did you enable the "Show Plus Sign" checkbox/property?
  23. Mitsubishi FX3U firmware...

    Thanks
  24. Mitsubishi FX3U firmware...

    Hello, Is it correct the firmware of an FX3U PLC cannot be updated?
  25. Hello, Is it possible to have a FX3U-ENET module on the right side of the PLC and a FX3U-ENET-ADP on the left side? If possible, how to specify the module number in FX Configurator-EN? Regards, Mark
