EtherCAT, EoE Routing

CODESYS
1

Can you provide an updated guide for connecting with an EtherCAT drive through CODESYS, then use EoE for configuration on a 752-8303?

I have successfully connected the drive, as it shows up as a connected device under my EtherCAT Master, but I have not been able to get the EoE routing successful for configuration (Control Techniques Digitax M753, attempting to use the Connect software).

I have been able to set X1 as my ethernet network, and have tried a couple of configurations on X2, both as 0.0.0.0 and as 192.168.2.1 (for routing). The M753 is set in the EoE as 192.168.2.2. I found a document that describes setting up a networking file in CC100 PLC to configure a TAP, but I don’t see that available in my setup.

When the X2 was set as 192.168.2.1 I was able to ping that with a response, but was not able to get a response from 192.168.2.2.

EoE is configured the same way on a 752-8303/8000-0002 as it is on a CC100 with a tap, so it sounds like you’re on the right track.

I did a quick test on my 752-8303 running firmware version 30, and it works as expected.

When you type “ifconfig tap0” in the controller’s CLI, does it look similar to the output below?

If it does, then verify the EoE setup in CODESYS.

Also, the CODESYS program needs to be in RUN mode for EoE to work.

I don’t have the same result when checking tap0:

I also don’t have the “networking” file to modify as shown in the CC100 documentation. How shall I set up the tap0?

I tracked it down.

cd /etc/init.d

That takes you to the directory where the networking file is.

Or the user can just use

nano /etc/init.d/networking

To edit the correct file.
