Here you have it!

Vinha_1Cuba represents LOGO1, and Vinha_2Cuba represents LOGO2. Both programs are in LAD.

I also added the network to the .zip file, with both programs in FBD. I have no idea why LOGO 2 isn't recognizing the information from LOGO 1.

EDIT: I hadn't updated the network, it had some errors. Now it should be correct, but still not working as desired.

Ideally I'd have a second flowrate to test on LOGO 2, but I'm still waiting for some material to arrive.

I can't read VW2 (VB2 + VB3 = analog input from flowrate sensor) on LOGO 2, and VW4 and VW6 aren't being received by LOGO 2 as well.

EDIT: I've updated the ZIP file in the previous post, LOGO 2 had some errors that I didn't update yesterday on the network, sorry.

I see, I had to define them as server and client in Ethernet Connections. I converted the files to FBD instead of LAD, and I was able to convert the words as you said, thanks!

By the way, is LOGO1 defined as the client because it will provide information to the server, which in turn only receives information?
