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

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??

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.

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/

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?

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.

Here's an example. Can anyone have a more elegant solution? forums.mrplc.com.gx3

Is this what you want?

Throw off please projects, too lazy to type yourself.
