Everything will be fine. When you use the ModBus TCP protocol, the device is identified by the IP address and this identifier is not used in ModBus TCP and requires 255 by default. It is needed if you have a ModBus TCP <-> ModBus RTU convector. The convector receives a ModBus packet via IP and then sends it to the RS-485 network using addressing to the device using this ID.

Slave ID adress 255. The parameters that I changed after resetting to the factory settings and the result of the ModBus TCP exchange. FR-A840 parametr (ModBus TCP - Only Read).frc2

Also the first time I had a problem with the address of the registers. This postscript is hard to spot.

After changing the settings, you need to reboot the power. Looks like it looks right. But I don't remember exactly (it was long ago). It seems that the parameters are also important: 79, 340, 550, 551. p.s. Another common recommendation is to reset to factory settings before starting the setup. Because someone before you could have changed something.

Modbus RTU ??? If nothing gets in the way, then on Monday in the office I will turn on the Inverter and copy the parameters. for modbus TCP. Or someone will be able to answer your question earlier.

Depends on which base controller you are using. You can check your build in the online configurator. https://www.mitsubishielectric.com/fa/ssl/products/cnt/plc_fx/ex/select/fseltool/fseltool.html I cannot answer the second part of the question.

Never worked with these controllers. If I understand your question correctly, check out these dedicated relays. melsec-a-series-the-service-group-разблокирован.pdf

The GT simulator seems to work only with the GX simulator. In a similar situation I installed GT SoftGOT2000 to communicate with a real PLC

I decided to post the instructions, for those who have a similar situation 1) We create "Window screen". We take out the standard keyboard. 2) Handle each key. I in google found the Unicode table Russian language. 3) In the settings, we specify the custom keyboard. And we indicate the number of the screen on which it is located. p.s. I don’t understand why Mitsubishi didn’t add keyboard options for all languages to the library ?

Good evening. There are a couple of questions (GS2110): 1) 32 symbol (unicode) = 32 word ??? OR 64 ??? 2) Is it possible to make full-sized keyboard ?? I've heard or seen somewhere that is possible. But I don't know where to start. 3) You can use other languages for the name of the recipes (Russian for example)? The site gives an error when trying to attach an image. Therefore, I had to use a third-party resource. https://pastenow.ru/79a0b07623d709cb9c072a9a0989077b https://pastenow.ru/61c3cee7fb3390944049c01e02340096 https://pastenow.ru/74fa625986a0336dce91c858a76bf064  

Check software version. Check PLC parameters.   https://forums.mrplc.com/index.php?/topic/13068-converting-from-fx2-to-fx3u-6402-memory-capacity-setting-error/

Sorry I didn't one zero. Drop 4. Look at registers 46-49. If you are reading DWORD register. It happens that LOW WORD and High WORD are reversed. An example from the manual on INVERTER FR-A800 https://pastenow.ru/ab746a0c4d9d4980d928e7944c390553   p.s. Sorry, but the site still does not allow image attachments.

https://pastenow.ru/09832ace3d720f810070bbd3ef6623e8 If these addresses are empty, check that in registers 46-49. If these addresses are empty, check that in registers 46-49. Somewhere I have seen this that they write 40,000+ and in fact 0+.

What does this have to do with Mitsubishi ?  Like a forum thread on Mitsubishi products. Sorry, I'm not familiar with Nexgene 2000. And I don't work for codesys.

Since the initial data is scarce. Maybe fit function block SP_ECPRTCL and Predefined Protocol Support Function.

Works !! Thank you so much. It seems that I tried all such blocks. Apparently I missed something. For two days I was looking for different options, I could not find.

Hello. Need help. If it is possible to copy a set of bits from DWORD to REAL. Without using direct addressing in D(W) register? Maybe there is a solution in ST ? The program for some reason swears at bit addressing.

Yes.   https://forums.mrplc.com/index.php?/topic/36347-dword-to-floating-point-problem/&do=findComment&comment=169549    CopyDwordToReal, Probably like this. Only necessary for FX5U (GX Works 3).    

550, 551 - Installed. 1434 - A typo in the inverter wrote correctly. 1449..1454 - I thought that I correctly set the range of IP addresses from which you can give commands. Thank you very much. Has earned !!!

Hello. There is a controller FX5U-32MP in the presence, the inscription "CC-Link IE Field Basic" and the Inverter (FR-A840-00170-E2-60) near the connector, the inscription "CC-Link IE Field Basic" on the front panel. I set up both devices according to the instructions. It turns out to read the state of the inverter (state, frequency). And I can not manage from the controller. Already all the settings that could have changed. Can you scribble what is wrong? p.s. Sorry for the bad english.

Does not work. Here is the list of parameters that are involved (most of them are by default). I will be grateful if you look and tell me what's wrong. 1.pdf
