Ethernet Communications Q series to Multiple FX3G

6 posts in this topic

I have a line that I'm integrating that requires the main machine (Q13UDVCPU) to communicate via the built in Ethernet port with 3 different up and downstream machines using FX3G controllers with FX3U-ENET modules.    We are using GX Works 2 software.

So far I'm having no luck with the Mitsubishi documentation, or online.  Some (old) sources say it is not possible, I hope that is not the case.

What I could really use is a working example program to look at and dissect.  But any help would be appreciated.

Well I can be quite easy if you have a new qnUDVCPU. The new types support Simple PLC communication.
Also your GX Works 2 should be up to date.

If not there FB available which you can use if the project has been made in structured mode

That sounds encouraging.   BUT, I should mention that I'm a Mitsubishi Noob.   I could set up comms on a Rockwell product with my eyes closed, but on Mitsubishi I don't know where to start.

Which version of GX Works 2 do you have ?

Or open you project. open the PLC parameters. Select the Built-in ethernet TAB.

Now look if in there is a button called Simple PLC communication in the bottom Left of this Tab.

As for getting up to speed with Mitsubishi:

My GX Works 2 is Version 1.550Y which appears to be a few revs old. 

That may explain why I don't have a Simple PLC Communication button on the Built-in Ethernet Tab  :(
