CODESYS - the IEC 61131-3 automation software

Hello
You need to install 3.5.10.10 to get the necessary libraries.
1. Compiler version should be set to 3.5.10.10 (Project-->Project Settings)
2. Remove Visu references (not supported) and all the libs it brings in.
3. The EtherCAT task has got confused. Delete the EtherCAT task then Delete the Master, then 'Add Device' and add a 3.5.10.10 EtherCAT master. Don't try and manually add an EtherCAT task; it does it automatically. See screen shot.

4. Select NIC by network name rather than MAC ID

Hi ph0010421, I used to try convert it to 3.5.10.10 but it not work, the library is still the latest. I followed your step when add EtherCAT master but I don't know why he still outside the Maintask .
Here some file I save as 3.5.10.10. Sorry about late reply, I've been busy so far.
Btw, thanks for youe help, I very appreciate it.

You hadn't made any of the changes I suggested, so I guess you didn't install 3.5.10.10 either?
Attached is a .project. If you didn't install 3.5.10.10 it will be missing libraries, but these can be downloaded with the 'Download Missing Library' button in the library manager.

I don't have the Beckhoff Device descriptions, so add these devices to the EtherCAT master manually.

I've installed v3.5.10.10 but everything didn't change.

What does the log say now?
Does the browse show both NICs? Try selecting the other NIC and change to LAN B.
One this is downloaded, try a 'Scan for devices' from the etherCAT master context menu. What does that see?

Hi ph0010421,
I don't know why but today when I was going to run the project to capture some pictures, it worked perfectly for me. This is the best way to begin a week.
Thanks for your help, I very appreciate it. Hope you guys have a nice week.

Great news
