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.

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?
-
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.

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: https://dl.mitsubishielectric.com/dl/fa/document/manual/plc/sh080809eng/sh080809engx.pdf

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.

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.

The only place where it is told about the PID controller, but there is no "PID" function block. Or am I blind (( Or MELSEC-L does not support such a function??

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?
-
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.

Unfortunately I am not familiar with Node Js. Reading from writing differs only by the function code inside the ModBus message. I always look at this cheat sheet when working with ModBus. https://ipc2u.com/articles/knowledge-base/detailed-description-of-the-modbus-tcp-protocol-with-command-examples/
-
FX5U have ModBus TCP (slave/Master). Maybe it will be easier on it? For ModBus TCP (slave) it is not necessary to write a program inside the PLC. In the "Enable" settings and you're done.

Become familiar with the following concepts: - Latch (1) - Latch (2)

Need more CapsLock.

I don't have a GT2107, but these projects should work. forums.mrplc.com - FX5U.gx3 forums.mrplc.com - GT2107.gx3.GTX -

https://www.youtube.com/watch?v=q7O7EeNBTZA 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 -

Probably an old version of the program ?? https://www.mitsubishielectric.com/fa/download/software/hmi/got/index.html

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

Try clearing / formatting the CPU memory. And upload a clean project. With default settings. If it does not help, wait for a response from more experienced users.
