    Hello. I will be very grateful for your help!


    There is a MELSEC-L controller (GX Works2), it is necessary to implement PID controllers.

    Question:
    Is it possible to work with 33 or more PID controllers at the same time?

    Why I have this question:
    1) There is a 
    dl.mitsubishielectric.com : MELSEC-Q/L/QnA Programming Manual (PID Control Instructions)
    On page №16, there is a table that says "Number of PID control loops: 32 loops (maximum)".

    2) In the

    dl.mitsubishielectric.com : MELSEC-Q/L Programming Manual (Common Instruction)

    On page №737, there is a description of the "PID" function block, where there is no limit on the number of uses. I saw a note about the CPU serial number.

    3) On the Mitsubishi website there is a library fb-cpu-pid_v110l_e.zip
    www.mitsubishielectric.co.jp : fb-cpu-pid_v110l_e.zip

    I can't figure out if there's a limit to how many PID controllers can work at the same time in a program. What is the difference between PID controllers (from the points above)?

    p.s. I liked the pid regulator from point №2 the most.

    It's an end of life product.

    I can provie you with the latest installer if you have a installation code for it.

    Or you can ask Mitsubishi Europe

    Please share, I have a key. I do not know from which specific version (key). But I think that it will fit the latest version of the program.

    I can't find the IEC Developer licensed installer anywhere.
    I checked the global, European and Japanese Mitsubishi sites.

    Why isn't he there? Can someone suggest where to find it?

    Hi Neverov,

    you can find this manual at

    https://dl.mitsubishielectric.com/dl/fa/document/manual/plc/sh080040/sh080040s.pdf

    for a list of other manuals for L-Series:

    https://www.mitsubishielectric.com/app/fa/download/search.do?kisyu=/plcl&mode=manual

     

     

    The problem is that everywhere in the manuals there was no PID function that does everything with one function. They are complex and fragmented. I was only able to find a description of it here:

    Hi Neverov

    There is a separate manual for PID.

    See attached pic. I can send it to you via email

    Thanks Neverov.Aleks@gmail.com

    Can't find it in search. By this name I constantly stumble upon another instruction, as in the e-Manual Viewer.

    Hello. I have worked with PID controller in IQ-R and IQ-F series. It took to apply in MELSEC-L. I found the same function block, but I can't find the documentation for it anywhere. In the "e-Manual Viewer" it finds a combination of PIDRUN, PIDINT and the like, but there is no description for the "PID" function block.
    Help find a description.

    you're program creation was for just ladder. You should create a program in structured instead and read out the program againhttp://.

    That is, before reading the project, create an empty project ? And only then read?

    Immediately after opening the program (without creating a new project), I clicked to read the project.

    A working controller FX3 on factory. It was necessary to subtract the project (using GX Works2) to save it in case of a PLC breakdown. Never faced such warnings before. What could it be because of? How to make sure that the read project can be used in the event of a PLC breakdown?

    Dear All,

    I have iQ-R R08ENCPU and I declare variables as var_global_retain but they are not actually retained

    The battery is OK, is particular, the PLC clock is OK

    Need strongly any ideas, where am I incoirrect

    Thanx.

    Become familiar with the following concepts: 

    - Latch (1)

    - Latch (2)

    Thank you in advance for answering my question.

    but I haven't been able to solve the problem.

    I'm very happy if you can show me how in detail so that "2 WORD" becomes "1 FLOAT"

    for example if D0 = 0X0002, and D1 = 0X23FF. I want the output to be D2 = 0X000223FF.

    I'm still really a beginner in the PLC world

    Here's an example.
    Can anyone have a more elegant solution?

    Hello all. First time post in this forum.

    I am hoping someone here can offer some advice or a solution to a problem I am having.

    I have a Modbus water meter from chinese that connected to my FX5U with ADPRW Instruction, but i have a problem. The cumulative flow from water meter is a 4-byte hexadecimal number, with the high bit first and the low bit last.

    I want the output from the PLC is real number FLOAT. can someone in this forum help me to combine 2 different WORD and create a single FLOAT.

    Here I Attached document from water meter.

     

    Thank you,

    Привет, ребята, я использую HMI GT2107-wtsd и ПЛК FX5U-32M с gx works3 и designer3, я установил простой код релейной диаграммы, чтобы проверить, что все работает, но я не могу открыть нормально закрытый контакт, когда я нажимаю кнопку на HMI и выключить свет? на скриншоте ниже показан код и кнопки HMI, когда вы просто смотрите на экран HMI, все индикаторы должны быть выключены, за исключением индикатора номер 2, поскольку он подключен к нормально замкнутому контакту, и я хочу, чтобы он открывался, когда я нажимаю кнопку на HMI рядом с LT2 (индикатор 2). Кажется, я не могу заставить его работать ...

    пожалуйста, помогите, спасибо.

    I had a look through all those links thank you for the help but what these are showing is how to simulate them together but I am looking to actually physically use the HMI to control the PLC if that makes sense

    GS2107 differs from Gt2107 with stripped-down functionality. Everything else is the same.

    When writing a project to the panel, select USB instead of Ethernet

    Привет, ребята, я просто ищу помощь, если возможно, я пытаюсь настроить HMI (2107-wtsd), но в GT Designer3 нет этой модели и нет моделей 2107 в раскрывающемся списке типа GOT. Как я могу показать свою модель? Я попытался установить тип GOT как G2105 и GT softGOT2000, и это не сработало, HMI отображается на белом экране с данными установочного пакета, но я не могу этого сделать, если он не находится в раскрывающемся списке GOT, правильно?
    Я приложил несколько фотографий, чтобы показать.
    HMI подключен к PLC через Ethernet, а ноутбук подключен к HMI через usb
    Я очень новичок в этом, поэтому мы используем испытательные стенды, поэтому, если что-то выглядит не так, мне очень жаль

    Probably an old version of the program ??

    I am newer to GT designer. Ive used it a couple times years ago but I cannot figure out how to create a 3 position switch and cant really find any info on it? Is there a special way to set a switch up so that eveytime the operator hits it it changes the state or picture of the switch from left to up then to right and back? im sure its probably just something that im not seeing in the properties menu but any input would be greatly appreciated. 

    SWITCH.PNG

    Take out the light bulb first.
    Then on top of it a transparent button.
    But in the plc or in the panel scripts, you need to reset the switch counter. Because the button will count until it overflows in a circle.

    Or hang up the M register on the button.
    And in the PLC program, add or subtract the number of lamp output to the screen.

    I don’t know any other options.

    In any unclear situation, reinstall Windows   ;)

    The length of the path to the executable file must not exceed (I don't remember how many) the number of characters. Copy the installation archive (folder) to the root of the C drive
