Hi,

I have a project which I have upgraded from V3.5.6. When I compile the project, the compilation is successful. However, when I download the project to the PLC, the error in the attached photo appears.
Runtime is: 3.5.16.10
IDE: 3.5.16.10
Device in project is: 3.5.16.10

Please advise,
Thank you!

Hi,
you need to install the CODESYS network driver under windows and add the component to the RTE
configuation.

Thank you!
I have added the component in the RTE and it is working now.
But how can I upgrade the Codesys network adapter in windows (from version 3.5.4 to the latest)? Where can I find the driver file?

And last, What is the difference between EtherCAT master and EtherCat master softmotion?

Hi,
1. this is just an error that version shows 3.5.4 usually the setup should update the drivers too.
You could check the date of these drivers in /Windows/System32/drivers/Cmp... they should all have the date from the release.
2. the only difference is that the ethercat frames will be send out on the before the iec task to have less jitter in sending the frames. ( Some drives react sensitive on sending them after the iec cycle)
