Hi, I am trying to make running communication via ModbusTCP, EtherCAT and ProfiNet on 2 plcs, I have one vitual on my PC running and a second one on Raspberry pi with Codesys runtime, I was able to make Modbus run a simple communication but I am struggling with EtherCAT and ProfiNet. Both PLCs are in one project.
On ProfiNet I get a ErrorFindEthernet message, I even tried installing winpcap and I added "sysEthernet" to configuration file.
On EtherCAT I am clueless I dont even know if I have the right devices connected.
Hi,
EtherCAT is not possible without additional hardware.
You need a gateway device to connect the two masters ( Control Win on your PC and the Raspberry Pi)
->EL6692 device
Profinetnet is possible without additional hardware.
Here is an example project including 2 PI's as plc's. ( one is Profinet Controller the other Profinet Device)

Hi, thanks for your answer, I looked at the project you provided, and it seems I have everything configured correctly,
I had changed CODESYSControl_User.cfg on Raspberry and as I said I have winpcap installed and running.
But it seems I cant get my slave to run, I dont know if there is problem with Ethernet adapter(I havent add sysEthernet component to raspberry tho, i dont know if I have to). My profinet slave device cannot get Ethernet information, it seems. But Slave gets 0 errors in Log, its pretty frustrating already. I am attaching screen of my project.
Thanks for your help.

Yes, I did add those lines, and firewall is off, I think my Raspi did something because it started to create virtual interfaces for Ethernet, for my testing purposes, I started Codesys on another PC and didn't use Raspberry in the end.
Communication went fine, now I will proceed to EtherCAT.
Thanks again for answers.

Hi,
did you add on pn device side (Pi)
/etc/CODESYSControl_User.cfg
[SysSocket]
Adapter.0.Name="eth1"
Adapter.0.EnableSetIpAndMask=1
'eth1' or 'eth0'
and check if on Windows side the firewall is diabled.
