    Just by looking at it, it seams to that simple bit(s) shifting...

    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.

    I read in a manual (W227E12_FINS_Commands_Reference_Manual.pdf) that there seems to be a command capable of doing such task.

    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.

    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.

    ooh i see, but what do you mean with "finger pointing"?

    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

    Thanks for the support. The verification was successful with the tool [PeakHMI] mentioned above.

    Still I am unable to connect KEPServer to PLC with same config. If there's anything you have tried, please so share.

    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.

    Hi friend! Please,

    I can't read your message.

    You can write in English?

    Thanks!

    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.

    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.

    Who could help me ? What is wrong ?

    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.
