No the EL6021, modbus is usually RS-485 signalling. Not so different from RS-232 but differential signals.
Edit. The USB to RS-485 is a much better option in this case to avoid the vertical learning curve.

Thx for your help!
You mean the EL6001? The lasting question would be how to tell ethercat to send the modbus data via the module. As an absolute newbie to ethercat and Linuxcnc it seems to be a very steep learning curve.
