Fx5-U Connection Issues

[programlayan]

Hello, I tried to connect FX-5U with mcprotocol. (With default ethernet configuration) Connected but timeout occured. (Port 1280 used) When I try to add SLMP and port 1281 connection refused. What can I do for connection? thank you.

I think the only way this will work with your CPU is if we add support for 3E frames. (Or another type, but 3E looks like it would support the most additional CPU types). I would be willing to do a bit of work on this but I don't have a test CPU other than an FX3U so I think the only way we could make this work is if someone else had some time and a test CPU to help get it working. I will see what I can do in the next week or two.

[programlayan]

Hello, Thank you for your response, I can test, also if you want to test too, I can send a remote connection for testing purposes too. Thank you.

[plcpeople]

OK I pushed a new version to the repository (but not to npm), and it seems to send the right packet in both ASCII and binary to read device memory. To activate the new code add connection options frame: '3E' and it would help if you added debug: true as well.

Use care in testing on a real PLC. I've tried to be careful but I have no way of testing these frames on a real CPU.

Hello, Thank you, I will try it, but Covid-19 reasons I am out of office since 6 April.

[plcpeople]

OK, let me know. COVID-19 is the reason I had time to work on this. Hopefully by 6 April things are better everywhere.

Try adding frame: '3E' and debug: true in the same object where you specify the port and IP address. It is still sending the same 1E frames as before without the frame option.

[programlayan]

Hello, I added SLMP by PLC, set its Protocol TCP and port 1281. There is no debug option here. (Please copy and paste the URL: https://ibb.co/L1wYTRm ) On the node side, I assigned debuglevel 99 and frame 3E. The current value of D100 is 26.

Ok, please try the latest commit.

Also, if that doesn't work, or if you want more features even if it does, check out this fork at https://github.com/Steve-Mcl/mcprotocol - you should be able to test the file in that version, with frame: '3E' and it should work. We're discussing merging those changes into this project.

I think you loaded the wrong file when updating as I can tell you're back to 1E frames there.

Hello I tried Steve-Mcl fork, it is working. Thank you.

Does it work with ethernet comm based fx5u and Q/L or R series plc?

Is Cc-Link supported?
