EtherCat for PC

I need to Implement an EtherCat master interface (on a windows PC or laptop) to one device only - what do you recommed - ideally with an API to do our own packets etc


Are you asking if we have a device that acts as an EtherCat master, or how to test one of are devices that is an EtherCat slave on your computer without having a master device?

I want to test one device that is an EtherCat slave using my computer which has only a single ethernet port

Sadly we do not have a device or software that can act as an EtherCat Master. We only have EtherCat slave devices.
